某型空气弹簧关键特性试验分析

Experimental Analysis of Key Characteristics for a Type of Air Spring

为获得准确可靠的橡胶空气弹簧产品试验数据,首先通过构建空气弹簧特性试验分析系统,进行该产品性能测试试验方案设计,利用绘图软件对弹性特性试验数据进行整合及归一化处理,再采用MATLAB拟合出产品的刚度特性曲线,最后通过气密性试验和台架寿命试验。试验结果表明,该试验方法为空气弹簧匹配悬架系统提供较好的选择区间,具有提高产品在实际工作状态中的可靠性。

In order to obtain accurate and reliable test data of rubber air spring products,firstly,an air spring characteristic test analysis system is constructed to design the performance test plan,and the drawing software is used to integrate and normalize the elastic characteristic test data,and then Using MATLAB to fit the stiffness characteristic curve of the product,and finally passed the air tightness test and bench life test.The test results show that the test method provides a better selection interval for the air spring matching suspension system,and has improved the reliability of the product in the actual working state.
