Experimental Study on the Mobility of Lightweight Vehicles on SandWorley, Marilyn Elizabeth 15 August 2007 (has links)
This study focuses on developing a better comprehension of the mobility of lightweight autonomous vehicles with varying locomotion platforms on sand. This research involves four segments.
The first segment is a review of military criteria for the development of lightweight unmanned ground vehicles, followed by a review a review of current methodologies for evaluating the terramechanic (vehicle-ground interaction) mobility measures of heavyweight wheeled and tracked vehicles, and ending with a review of the defining properties of deformable terrain with specific emphasis on sand. These present a basis for understanding what currently defines mobility and how mobility is quantified for traditional heavyweight wheeled and tracked vehicles, as well as an understanding of the environment of operation (sandy terrain) for the lightweight vehicles in this study.
The second segment involves the identification of key properties associated with the mobility and operation of lightweight vehicles on sand as related to given mission criteria, so as to form a quantitative assessment system to compare lightweight vehicles of varying locomotion platforms. A table based on the House of Quality shows the relationships—high, low, or adverse—between mission profile requirements and general performance measures and geometries of vehicles under consideration for use. This table, when combined with known values for vehicle metrics, provides information for an index formula used to quantitatively compare the mobility of a user-chosen set of vehicles, regardless of their methods of locomotion. This table identifies several important or fundamental terramechanics properties that necessitate model development for robots with novel locomotion platforms and testing for lightweight wheeled and tracked vehicles so as to consider the adaptation of counterpart heavyweight terramechanics models for use.
The third segment is a study of robots utilizing novel forms of locomotion, emphasizing the kinematics of locomotion (gait and foot placement) and proposed starting points for the development of terramechanics models so as to compare their mobility and performance with more traditional wheeled and tracked vehicles. In this study several new autonomous vehicles—bipedal, self-excited dynamic tripedal, active spoke-wheel—that are currently under development are explored.
The final segment involves experimentation of several lightweight vehicles and robots on sand. A preliminary experimentation was performed evaluating a lightweight autonomous tracked vehicle for its performance and operation on sand. A bipedal robot was then tested to study the foot-ground interaction with and sinkage into a medium-grade sand, utilizing a one of the first-developed walking gaits. Finally, a comprehensive set of experiments was performed on a lightweight wheeled vehicle. While the terramechanics properties of wheeled and tracked vehicles, such as the contact patch pressure distribution, have been understood and models have been developed for heavy vehicles, the feasibility of extrapolating them to the analysis of light vehicles is still under analysis. A wheeled all-terrain vehicle was tested for effects of sand gradation, vehicle speed, and vehicle payload on measures of pressure and sinkage in the contact patch, and preliminary analysis is presented on the sinkage of the wheeled all-terrain vehicle.
These four segments—review of properties of sandy terrain and measures of and criteria for the mobility of lightweight vehicles operating on sandy terrain, the development of the comparison matrix and indexing function, modeling and development of novel forms of locomotion, and physical experimentation of lightweight tracked and wheeled vehicles as well as a bipedal robot—combine to give an overall picture of mobility that spans across different forms of locomotion. / Master of Science

Tamaño de mercado, crecimiento del pbi per cápita y políticas públicas como factores internos del perú que influenciaron las estrategias y modalidades de ingreso de las marcas chinas del sector automotriz de vehículos livianos en el mercado peruano en el período 2006 - 2019Núñez del Prado Anzardo, María José, Sayan Bernal, Renzo Enrique 28 March 2022 (has links)
El proceso de internacionalización es complejo y demanda el análisis de abundantes variables que pueden evaluarse desde una perspectiva externa o interna, sin embargo, existen algunas variables que por su importancia deben ser estudiadas cuidadosamente. La presente investigación pretende contribuir en ese sentido teniendo como objetivo, comprender cómo ciertos factores internos del Perú han influenciado en las estrategias y modalidades de ingreso de las marcas chinas del Sector Automotriz de vehículos livianos en el mercado peruano en el periodo 2006 - 2019, lo que nos permitirá entender, cómo ha evolucionado las relaciones comerciales en el sector automotriz con la República China y la importancia que dichos factores internos propuestos en la investigación tales como: El tamaño de mercado, el crecimiento del PBI per cápita y las políticas públicas, han contribuido con la evolución de las relaciones comerciales entre ambos países, a partir de la cual podremos hacer inferencias sobre el futuro de la evolución de las relaciones comerciales. Su importancia radica, entre otras, en que, una vez verificadas las hipótesis, y finalmente definidas las conclusiones, el estudio se configure en un material de consulta que establezca una ruta adecuada para consolidar objetivos a través de la simbiosis que se debe lograr en los términos de intercambio. Por un lado, el estudio pretende ayudar a los analistas en la toma de decisiones específicamente en el proceso de internacionalización de las marcas chinas al momento de ingresar al país de una forma más rápida, eficaz y eficiente, y por el otro, al entender este mecanismo; que el Estado pueda desarrollar políticas públicas que permitan modernizar el mercado automotriz peruano y, a su vez, se cumplan con los compromisos internacionales relacionados con la reducción de emisiones, entre otros.
De la revisión de los antecedentes se ha hecho evidente que el tema materia de investigación tiene mayor número de antecedentes internacionales, lo que nos permite evidenciar que en el ámbito nacional es un tema poco estudiado, y en la mayoría de los casos se han estudiado variables dispersas, sin embargo, los factores internos considerados en el presente estudio siempre han estado presentes; por esa razón, el problema central de la investigación es determinar cómo esos factores internos que han venido apareciendo de manera recurrente en los antecedentes, han influenciado en el proceso de internacionalización de las empresas chinas de vehículos ligeros.
Así mismo, esta investigación pretende servir como referencia para futuras investigaciones, tanto de enfoque cualitativo como cuantitativo, orientadas a las estrategias y modalidades de ingreso de las marcas chinas al mercado peruano. En la presente investigación se empleó la metodología cualitativa; además un alcance descriptivo – exploratorio, con un método de recolección de datos de entrevistas a profundidad. Las conclusiones obtenidas en esta investigación servirán de guía para profundizar en otros estudios que coadyuven a orientar a los estrategas, sobre las estrategias y modalidades de ingreso teniendo en cuenta las oportunidades de mercado, en contraste con la realidad específica de su empresa. / The process of internationalization is complex and requires the analysis of many variables that can be evaluated from an external or internal perspective. However, there are some variables that, because of their importance, must be studied carefully. The aim of this research is to understand how certain internal factors in Peru have influenced the strategies and modalities of entry of Chinese brands in the Automotive Sector of light vehicles in the Peruvian market in the period 2006 – 2019, which will allow us to understand how the commercial relations in the automotive sector with the Republic of China have evolved and the importance that these internal factors proposed in the Market size, per capita GDP growth and public policies have all contributed to the development of trade relations between the two countries, from which we can draw inferences about the future development of trade relations. Its importance lies, among other things, in the fact that once the hypotheses have been verified and the conclusions finally defined, the study is configured as a reference material that establishes an appropriate path for consolidating objectives through the symbiosis that must be achieved in the terms of trade. On the one hand, the study aims to help analysts make decisions specifically in the process of internationalization of Chinese brands when entering the country more quickly, effectively and efficiently, and on the other hand, to understand this mechanism; on the other hand, to enable the State to develop public policies to modernize the Peruvian automotive market and, at the same time, to comply with international commitments related to the reduction of emissions, among others.
From the review of the background, it has become clear that the subject of research has a greater number of international backgrounds, which allows us to show that at the national level it is a subject little studied, and in most cases scattered variables have been studied. However, the internal factors considered in this study have always been present; for this reason, the central problem of the research is to determine how these internal factors, which have been recurring in the background, have influenced the process of internationalization of Chinese light vehicle companies.
Likewise, this research aims to serve as a reference for future research, both qualitative and quantitative, oriented to the strategies and modalities of entry of Chinese brands to the Peruvian market. In this research, qualitative methodology was used with a descriptive and exploratory scope and in-depth interviews were used as a method of data collection. The findings of this research will serve as a guide to further studies that help to guide strategists on the strategies and modalities of income considering market opportunities, as opposed to the specific reality of their company. / Tesis
