| 摘 要： | 建立了活塞、活塞环、活塞销和缸套的耦合模型，采用接触对、设定接触热阻的方法对耦合模型进行了二维和三维瞬态温度场的分析。对采用接触模型和粘贴方式模型的分析结果做了比较。对活塞组的机械负荷及热负荷做了耦合场静态分析。

Finite Element Analysis on a Coupled Model for Piston Assembly of a Diesel Engine |
| |
| Abstract: | The coupled models for piston,piston rings,piston pin and cylinder of a diesel engine are built,in which the contact pairs are defined and thermal contact resistances are determined Based on this,the 2D and 3D transient temperature fields are analyzed The static coupled analysis with both thermal and mechanical loads applied is also carried out |
