轨道车辆空调送/回风口处橡胶密封条的压缩性能分析

Analysis on Compression Performances of Rubber Sealing Strips at Air Supply/Return Outlet of Railway Vehicle Air-conditioner

基于Mooney-Rivlin本构模型,对轨道车辆空调送/回风口处橡胶密封条(简称橡胶密封条)的压缩性能进行分析,并与橡胶密封条的单轴压缩试验(简称试验)测试的压缩性能进行对比。结果表明:橡胶密封条试样的仿真分析与试验测试的压缩量误差在整个压缩区间内均小于10%,采用Mooney-Rivlin本构模型分析橡胶密封条试样的压缩性能是可靠的;橡胶密封条的仿真分析与试验测试的压缩量误差在整个压缩区间内均小于10%,进一步验证了采用Mooney-Rivlin本构模型分析橡胶密封条的压缩性能的可靠性。本研究可为其他橡胶制品的非线性特性分析提供参考。

Based on the Mooney-Rivlin constitutive model,the compression performances of the rubber sealing strips at the air supply/return outlet of railway vehicle air-conditioner(referred to as rubber sealing strip)was analyzed,and compared with the experimental results by uniaxial compression test(referred to as the test).The results showed that,for both the rubber sealing strip sample and the rubber sealing strip,the errors between the compression values obtained from the simulation analysis and the test were less than 10%in the whole compression range,which indicated that it was reliable to use Mooney-Rivlin constitutive model to analyze the compression performance of the rubber sealing strip sample and the rubber sealing strip.The research outcome could also provide references for the analysis of nonlinear characteristics of other related rubber products.
