Analytical Matching Method and Experimental Application of Inertial Suspension Damping Ratio
摘要
Abstract
Facing the shortage of efficient and practical damping ratio analytical matching methods in the selection,matching,and experimental data analysis of hydraulic shock absorbers in automotive inertial suspension systems,a golden-section-based analytical matching method for the optimal damping ratio of such systems is proposed.Firstly,based on the dynamical model of the automotive inertial suspension system and random vibration theory,the analytical expressions of the vehicle body's vertical vibration acceleration,wheel dynamic load,and the root mean square responses of suspension dynamic deflection are derived.Secondly,considering safety and comfort of vehicle,the damping ratio formulas are deduced.Then,the golden-section-based method is used to develop the matching method.Finally,its effectiveness is verified by comparing example design with numerical optimization.The results indicate that the relative deviation between this method and the numerical optimization results is less than 5％,demonstrating high accuracy and practicality.This method offers simple and practical formulas,clarifying the relationship between vehicle parameters and the optimal damping ratio,avoiding numerical complexity for easy engineering use and experimental and training.关键词
