Driving Dynamics of ATV vehicle 6x6
Juhász, Vojtěch ; Hejtmánek, Petr (referee) ; Blaťák, Ondřej (advisor)
This thesis focuses on the analysis of the driving dynamics and suspension of six-axle ATVs, which are increasingly used by armies for transporting cargo and assisting troops in various combat situations. Due to the unique design of the three-axle, equal wheelbase chassis, the vehicle's suspension behavior presents a significant challenge. The objective of this work is to build a multibody vehicle model using MSC Adams software, analyze the vehicle's handling characteristics in rough terrain and other driving maneuvers, and optimize the suspension and damping characteristics of each axle to improve the vehicle's handling characteristics. The results of this work will provide useful information for the design and development of more efficient and safer solutions for military and civilian applications.
Progressive conception of off-road vehicles with respect to traction properties
Michal, Jakub ; Prikner, Patrik (advisor) ; Jindra, Petr (referee)
The aim of bachelor thesis was compile a summary of meaningful traction and construction chassis parameters containing fundamental principles of contemporary off-road trial race cars. The introduction part showed a short presentation of off-road car trial races. The aim of the work, it was necessary establishing basic parameters of off-road trial race cars as a basis for the design of best race trial cars. Firstly, the parameters were used as stoned to a best off-road trial car design. These parameters have been arranged into two chapters Static, design parameters and Dynamic, traction properties. Then subparameters of off-road trial car have been determined as a specific example in the thesis. The analysis of these outputs confirmed close relationship and dependence fully. Finally, methods have been specified using a fundamental terramechanics approaches implemented in calculation of required driving torque under specific terrain conditions.
