摘要
汽车悬架性能测试是机动车安全运行检测中的一个重要项目。本文在建立检测车辆悬架振动力学模型和运动方程的基础上,分析并确定了悬架性能的评价指标。针对汽车悬架测试台的基本结构和受力过程,设计了高精度力传感器和速度传感器输出信号的调理模块。采用工业控制计算机直接采集车轮垂直接地力与激振台面频率,提高了测试系统的精度和实时性。实测证明,该系统完全能够满足汽车悬架性能测试时的动态要求,具有较高的可靠性。
The suspension performance test for automobiles is an important item in safety operating detection for power driven vehicles. Based on test vehicle suspension vibration mechanics model and motion equation, suspension performance evaluation index were analyzed and ascertained. In accordance with the basic structure and features of forcing process of automotive suspension tester, the high precise conditioning module for outputs of force sensor and velocity sensor was designed. By using IPC （Industrial Personal Computer）, the vertical wheel contact force and the excited vibrant platform frequency are directly collected. The accuracy and the real time performance of the test system are enhanced. The test proves that the dynamic demand of automotive suspension performance test is fully satisfied and the system offers high reliability.
