Abstract:

Pseudo excitation method of stationary random vibration in time domain is summarized and analyzed， the pseudo excitation method of non-stationary random vibration in space domain is established. Based on the transformation relationship of variables and their derivatives between time domain and space domain， the vehicle vibration model in space domain is derived from the vehicle vibration model in time domain， and the spatial frequency response characteristics of vehicle vibration and acceleration in time domain are built. According to the two degree of freedom single wheel model of vehicle vibration， the expressions of virtual road roughness， virtual vibration response variables and statistical characteristics of vibration response variables are determined. The parameters of a car and a typical driving condition are used to analyze the variation law of statistical characteristics of vibration response variables. The results show that the method presented is suitable for solving the statistical characteristics of the vehicle non-stationary random vibration response variables.

Key words: vehicle engineering, non-stationary random vibration, pseudo excitation method, space domain, spatial frequency response characteristics
