摘要：
谐振式悬架检测台是目前被广泛使用的悬架检测设备，现有关谐振式悬架检测所建模型反映的检测参数不够全面，该文建立基于整轴结构的谐振式汽车悬架检测模型，对谐振式悬架检测模型进行Matlab/Simulink仿真分析和实验研究，通过对检测设备、仿真模型以及人为因素的角度分析悬架检测过程中对悬架吸收率的影响。仿真分析及实验研究表明：设计合理的谐振式悬架检测设备对检测结果影响不大，整轴结构模型中未被检测侧悬架减振器、弹簧发生故障时对检测侧的悬架吸收率干涉较小，人为因素中被检测车轮与台面中心线在y轴方向上的偏移量对检测结果影响非常明显。

Abstract: Resonant suspension test bed is currently widely used for suspension test. As existing model established for resonant suspension test does not have comprehensive testing parameters, this paper established a model for resonant suspension test based on whole shaft structure. The paper conducted Matlab/Simulink simulation analysis and experiment for the resonant suspension test model and analyzes the influences to suspension absorption rate in suspension test process from the aspects of testing equipment, simulation model and personnel. Simulation analysis and experiment results show that reasonably designed resonant suspension test device has little effect on the test results, and the suspension shock absorber and spring at the untested side of whole shaft structure model has small interference on the suspension absorption rate at the tested side in case of faults while the offset of the tested wheel and the offset of bed center line in y-axis direction have obvious influences on test results.
