Modeling and design of an electric all-terrain vehicleChevrefils, Adam R. 15 January 2009 (has links)
This thesis describes and evaluates the conversion of a conventional gasoline powered all-terrain vehicle (ATV) to an electric ATV. Preliminary studies are performed to obtain initial power and torque requirements for the vehicle. A detailed simulation model of the mechanical load is written and compared to manufacturer supplied data. The load model is then combined with a comprehensive electronic drive and motor simulation using an electromagnetic transient simulation program (PSCAD). A prototype of the vehicle is constructed by selecting the main components, an electric traction motor, batteries and a custom motor drive, using the simulation results. The results of both the simulation and prototypes are compared and evaluated. / February 2009

Taiwan Motorcycle Industry of Competitive Strategy - A Case Study of All Terrain Vehicle industry.Wu, Chun-Chieh 26 June 2007 (has links)
Abstract
The main core of this study is ATV industry in Taiwan to look for new development field. Basic on this point of view and Taiwan experience, this study analyses the ATV industry and market strategy for Taiwan manufacturer. From understanding the ATV industry further to analyses the currently development situation in Europe, American and Japanese market and the operating situation of main manufacturer assist with SOWT and Five Forces Framework analysis to help the manufacturer have more competition opportunity and offer the future development suggestion.
The conclusion is as below:
1. The competition strategy of Taiwan ATV industry exist competition price and non-competition price strategy. The manufacturer must be in leading position of the new vehicles development in order to be the leader in this market.
2. As the market grow, the manufacturer must take difference strategy to win the customer confidence, and the quick changing of the out looking will be the key trend of the market. So to own the tooling development and production ability will make the products in great use.
3. The ATVs are mostly used on risky environments so the production liability are more important than others feature. In some countries, the end users form ATV club and in this way " brand reputation" is going to be important part.
4. The new manufacturer of ATV must take price strategy to win one place in the market.
5. The completive price is a short - term strategy, only the products difference can make the profit in long - term.
6. The future completion of Taiwan ATV industry decides on new technology and brand value increasing, not on price.

Design of Steering Mechanisms of All-Terrain VehiclesChang, Ming-Chu 19 June 2001 (has links)
All-Terrain Vehicles, usually called ATVs, are a popular product in the leisure sport market. The steering mechanisms is one of the important components of ATVs to obtain better maneuverability. The purpose of this work is to develop a systematic design procedure for the steering mechanisms of ATVs. First, the particularities and the requirements of ATVs are investigated to induce the basic characteristics. Second, to carry out the creative design of steering mechanisms by using the systematic procedure of creative mechanism design. Third, to deduce the analytic theory of angle displacement, torque and stability for the design of steering mechanisms. Then a computer aided analysis program are written. Finally, to establish the quantitative design specification of the steering mechanisms of ATVs. Then the dimension synthesis and the steering mechanism to integrate with body of ATVs are illustrated with an example.

CHARACTERISTICS OF ALL-TERRAIN VEHICLES AND THEIR OPERATORS ON KENTUCKY FARMSWilson, Jessica L. 01 January 2012 (has links)
All-terrain vehicles (ATVs) were first developed and marketed in the U.S. in the 1970s. They have soared in popularity for occupational and recreational uses since that time. In 2008, there were approximately 10.2 million all-terrain vehicles (ATVs) in use in the United States. In 2001, it was estimated that 23 million Americans rode ATVs; 69% were adults and 31% children (CPSC, 2003). Deaths and injuries from ATVs have increased over time. According to the U.S. Consumer Product Safety Commission, Kentucky led the nation for ATV deaths from 2002-2006, with increasing numbers of fatalities annually.
ATV use on farms is increasing across the country because the vehicles provide an efficient and reliable replacement for horses and tractors for farm work, such as checking livestock, feeding, or fence repair. Aging farmers and farmers with physical disabilities can often increase their productivity by using ATVs for their transportation needs on the farm. ATVs also serve as an inexpensive and popular recreational vehicle used by families especially in rural areas.
In 2001, there were an estimated 481 ATVs per 1,000 (CI95% ± 27) farms in the southern region of the U.S. A literature review and a descriptive cross-sectional study were conducted. The specific aims of this dissertation were to:
1. Critically analyze the state of the science on ATV-related injury risk factors and explore recreational and occupational use of ATVs on farms.
2. Describe individual characteristics and demographic factors that are associated with ATV ownership and ridership among adult farmers.
3. Describe individual characteristics and environmental factors that are associated with ATV injury on farms.
4. Test models for predicting ATV ownership, ATV ridership, and ATV injury risk factors among adult farmers.

STATISTICAL ANALYSIS OF INJURY DATA AND THE CONCEPTUAL DESIGN OF A ROLLOVER PROTECTIVE STRUCTURE FOR AN ALL-TERRAIN VEHICLEParvathareddy, Bhavana 01 January 2005 (has links)
The rising statistics of fatal and non-fatal injuries involving an all-terrain vehicle has called for an analysis of the accumulated data from the past years. The analysis has led to the conclusion that in the past years, the fatal and non-fatal injuries have been rising rapidly in spite of the consent decrees which were brought into effect from 1988-1998 by the consumer product safety commission. A necessity to provide increased safety while riding an all-terrain vehicle is recognized. Rollover protective structures which were used with successful results in curbing the injuries on agricultural tractors have been identified as having a potential to serve the purpose. A conceptual design of an automatically deployable rollover protective structure has been dealt with, in the thesis.
