Quantitative Research on Contribution Degree of Vibration Affecting Factors of Vehicle Suspension System Based on Robustness Analysis

Abstract

Suspension system is the key component affecting vehicle ride comfort and finding out the main factors affecting suspension system vibration is the precondition of controlling suspension system vibration and improving vehicle comfort. Based on the principle of robustness analysis, the robustness analysis process of suspension system vibration influencing factors is constructed, in order to solve the problem, the three levels of front suspension stiffness, front suspension damping, rear suspension stiffness and rear suspension damping are selected, the experiment design scheme is adopted, power Spectrum of Class A road is used as input excitation source for suspension system simulation, the weighted acceleration root mean square simulation experiment of suspension system vibration under the influence of multiple factors is carried out.

Influence of the Hook Position on the Vertical Vibrations of an Automobile Exhaust System: Application of the Robust Optimization Design

“…Iyer et al [16] compared the finite element analysis mode with the experimental analysis mode to obtain the influence trend of the specific frequency band on the natural frequency. Xiong et al [17] utilized the robustness analysis method to study the vehicle suspension system. Through the analysis of the experimental data, the quantitative data of the contribution of the changes of suspension damping and stiffness to the vibration of the suspension system were obtained.…”
