摘要
通过试验对PU衬垫的硬度及在不同变形量下的比压进行了测试,对测试结果经曲线拟合和回归分析,建立了PU衬垫硬度与比压的关系式。
The test of PU lining hardness was introduced, the test of PU lining stress under different strain was illustrated. Testing data was processed with the method of curve fitting .Regression analysis was made to testify the reliability of the result. A formula of relation of PU lining hardness between stress was established.
