The Simulation Of Vehicle Vibration

Taking account of the automobile vertical direction vibration, transferred the actual vehicle into reasonable and easier model, established a 10-DOF-Model of the vehicle vibration, given damping matrix, rigidity matrix and the quality matrix of the model.Based on vibration theories and the analysis of the model , using main vibration shape and the natural frequency ,defined the concept of parameter sensitivity ,and got its formula .Based on this foundation, defined the concept of the appraisement coefficient of adjustment automobile rigidity parameter, and give the calculation equation.Got the transfer function of the vehicle, and theoretically got responds of the vehicle . When joined the inputs of road surface data in the future, it can simulate the moving of a vehicle.Using Matlab with VC, the simulating software of vehicle-vibration-analysis is made. This software interface is easy to use. Especially, it can run independently under Windows. The software can complete mode analysis, sensitivity analysis and parameter adjustment appraisement coefficient .it also can draw transfer function. All results are saved as file. Those files can be opened by other software, such as word board...
