An investigation into the promotional activities employed by the motorcycle businesses in the Nelson Mandela Metropolitan area

Gouws, Aldo January 2004 (has links)
The motorcycle industry is well established in South Africa, but has not nearly reached its full potential. This study investigates how this situation can be improved by enhancing the promotions of motorcycles in the Nelson Mandela Metropolitan Municipality (NMMM) area under investigation. Motorcycle businesses in this area currently compete with a disadvantage in the transportation market. Motor vehicles are assembled in this area whereas motorcycles are not, and this creates various work opportunities and brand loyalty for the motor industry. The Government also offers import rebates to motor vehicle exports. The cost, prejudicial attitudes and road safety of motorcycles contribute toward the difficulties faced by the motorcycle industry, which prevent the growth of this market. This market usually requires potential customers to have a passion for motorcycles to turn them into actual customers. To overcome these difficulties an investigation was conducted to determine which promotional activities the motorcycle businesses in the NMMM area employ. This study identifies the motorcycle businesses’ promotional shortcomings and makes suggestions for improvement. Promotional activities are vital since motorcycles are at a disadvantage when compared to motor vehicles in the NMMM area. One of the best ways the motorcycle businesses can successfully compete in the transportation market is to make use of promotions to make potential customers aware and enhance their support of the motorcycle businesses. For this reason the promotional variables (advertising, direct marketing, personal selling, sales promotions and public relations) should be exploited to its fullest to enhance potential customers’ support of motorcycles. This process can also create brand loyalty and equity, which will retain customers over the long term. Communication with a market is essential to achieve this and to inform and remind potential customers about the products available.

Towards Safer Rides: Measuring Motorcycle Dynamics with Smartphones

Stanglmayr, Maximilian, Bäumler, Maximilian 26 October 2020 (has links)
Motorradfahrer gehören zu den am meisten gefährdeten Verkehrsteilnehmern im Straßenverkehr. Häufig ist die Unfallursache ein Kontrollverlust auf Landstraßen, der durch Ausnutzung des physikalischen Potenzials in Form von größeren Schräglagenwinkeln vermieden werden könnte. Gleichzeitig sind in der Realität gefahrene Schräglagen über eine größere Gruppe von Fahrern und eine längere Strecke unbekannt, was vor allem auf die erforderliche spezielle Messtechnik zurückzuführen ist. Der Schwerpunkt liegt daher auf der Entwicklung eines kostengünstigen Messverfahrens zur Messung der Schräglagenwinkel von Motorrädern. Smartphones zeichnen sich in der Regel durch integrierte Inertialsensoren aus, die für die Erfassung der Fahrdynamik von Motorrädern geeignet sind. Mit Hilfe einer auf die Anforderungen zugeschnittenen Smartphone-App zur Erfassung von Messdaten auf dem Motorrad werden die Daten der Sensoren aufgezeichnet. Anschließend werden mittels einer Offline-Auswertung die Drehwinkel zwischen dem Smartphone und dem Motorrad-Koordinatensystem bestimmt, die inertialen Messdaten transformiert und der Schräglagenwinkel berechnet. Ein wesentlicher Bestandteil ist die Validierung der entwickelten Messkette durch einen Vergleich der Ergebnisse mit einem hochpräzisen Messsystem. Dieser wurde auf verschiedenen Strecken zur Bestimmung der Datenqualität durchgeführt. Als Machbarkeitsstudie diente eine Probandenstudie, die die Praxistauglichkeit der Messkette bestätigte. Die Studienergebnisse werden zusätzlich auszugsweise dargestellt und diskutiert. Die erfolgreiche Validierung auf verschiedenen Strecken, die Praxistauglichkeit der Datenerfassung und die Genauigkeit des Messsystems ermutigen dazu, die Smartphone-App auf ein größeres Panel von Testpersonen auszurollen und damit Daten über ein größeres Fahrerkollektiv zu erheben.:Introduction, State of Research, Methods, Measurement Chain Verification, Results and Discussion, Conclusion / Motorcyclists are among the most vulnerable road users in road traffic. Often, the cause of accidents is a loss of control on rural roads which could be averted by making use of the physical potential in terms of larger lean angles. At the same time, in reality driven lean angles over a larger group of riders and a longer route are unknown which is mainly due to the special measuring technology required. The focus is therefore on the development of a low-cost measurement method for measuring the lean angles of motorcycles. Smartphones are usually characterized by integrated inertial sensors, which are suitable for the acquisition of motorcycle driving dynamics. Employing a smartphone app tailored to the requirements for collecting measurement data on the motorcycle, the data of the sensors are recorded. During the offline evaluation, the rotation angles between the smartphone and the motorcycle coordinate system are determined, the inertial measurement data are transformed and the roll angle is calculated. An essential part is the alignment of the developed measurement chain with a high-precision measurement system. This was carried out on different routes and thus the data quality was determined. As a feasibility study, a test person study with several participants was carried out, which confirmed the practical suitability of the measurement chain. Hence, the study outcomes are briefly shown and discussed. The successful validation on different routes, the practical suitability of the data acquisition and the accuracy of the measurement system encourage to roll out the smartphone app to a larger panel of test persons and thus to collect data on a larger driver collective.:Introduction, State of Research, Methods, Measurement Chain Verification, Results and Discussion, Conclusion

Úprava přední vidlice motocyklu / Modification of the front fork of the motorcycle

Smolka, Josef January 2017 (has links)
The aim of this thesis is to investigate the force loading of the front telescopic fork girder of the motorcycle and its impact on the structure of the girders. The force effect in fork storage is solved by a mathematical model in Adams View based on calculated and experimentally determined parameters. Managed to gather a series of data and parameters of the Triumph Daytona 955i. The created model achieves high accuracy in terms of motorcycle kinematics. The benefit of this work is to get an overview of the forces acting in the suspension of the front wheel of the motorcycle.

Systém odpružení a tlumení motocyklu / Motorcycle Springing and Damping System

Filka, Tomáš January 2019 (has links)
This thesis consists of theoretical overview about motorcycle chassis and suspension systems as well as information about springs and dampers. It is also focused on practical usage of multibody simulation for motorcycle suspension testing which leads to the development of series of virtual riding tests built within MSC Adams View software environment. Then the results are further discussed together with suggestions for future improvement of this model.

Analýza měřených dynamických stavů motocyklů / Analysis of measured dynamic states of motorcycles

Tobiáš, Martin January 2019 (has links)
This thesis, within a long-term project at the Institute of automotive engineering at FME BUT, aspires to prepare a motorcycle for analysis of its dynamic riding behavior. A multi-body model of a motorcycle is created based on the measured parameters and a system for measuring driving conditions is designed. The necessary motorcycle parameters were measured using a 3D scanner and through experiments aided by computer technology and CAD software. This laid the foundation for the follow-up research and development work.
