多场耦合下压缩机活塞杆失效分析
首发时间:2018-04-20
摘要:在Pro/E中建立了某往复式压缩机曲柄、曲轴、活塞杆、活塞、缸体的三维模型,装配并同步到有限元软件Comsol Multiphysics模型的几何节点中,结合多物理场耦合理论,建立了温度场、流场、应力场的数学模型,通过理想气体状态方程实现物理场之间的耦合。结果表明,多物理场耦合作用较单物理场作用在活塞杆失效分析问题上优势明显,流-固-热三场耦合作用是活塞杆失效的主要原因,为活塞杆的可靠性研究提供了一种新的思路。

A Failure analysis on the piston rod of a compressor under multi-field coupling
Abstract:Build the 3D models of components of a reciprocating compressor in Pro/E, such as crank, crankshaft, piston rod, piston and cylinder, assemble and convert the assembly into the geometry node of the FEM software Comsol Multiphysics. And then combine the Multi-field Coupling theory, establish the mathematical models of the temperature field, the flow field and the stress field, make the three-fields coupling come true through the Ideal Gas Law. The results show that the multi-physical field coupling is superior to the single physical field in the failure analysis of the piston rod,thefluid-solid-heat three field coupling effect is the main reason for piston rod failure. which provides a new idea for the reliability research of the piston rod.
