In passive safety of vehicle in transport, it is important to study vehicle crash process. This paper shows a model that a SUV car collides in front of a wall, using finite element method and digital simulation. We analyze vehicle structure and crash response signals to determine crash impulse and passengers’ deformation. In the results, 2 parameters are determined including: maximum acceleration ...Show More
The fuel consumption of a car is affected by the technical parameters of the car, the road surface and complex operating conditions. In determining the fuel consumption, it is necessary to choose specific criteria that can be determined quantitatively such as the vehicle's running cycle, vehicle speed or vehicle mass, which are the kinematic parameters of the car. Using the Matlab Simulink softwar...Show More
This paper focuses on analyzing the relationship of gear's surface roughness and dimensions to friction moment in drive differental of car when the gear pairs rotate around a symmetry axis. The simulation has determined the relationship of tooth surface contact roughness and cylinder radius on the ratio of input acting load and frictional moment helps to determine mechanical efficiency of gear tra...Show More
This paper presents the dynamics simulation of the Cardan shaft in Automotive using the Jeffcott model. The simulation is implemented in Matlab Simulink. The input of the model is the mass of balanced. Bending and torsional vibrations of the Cardan shaft are analyzed. The simulation is created based on the condition of an automotive operating at a constant velocity of 60 km/h. The result of the si...Show More
