摘要
以某天然气发动机为研究对象,利用Ansys有限元软件对活塞温度场进行了数值模拟,并对活塞在各种载荷下的应力与变形进行了分析与对比,为深入了解天然气发动机活塞应力分布、活塞与缸套的变形匹配提供了一定的理论依据。
For a NG engine, the temperature field of piston was simulated with ANSYS FE software, and the stress and strain of piston under different loads were analyzed and compared. The simulation brought some theoretical reference for understand- ing NG engine piston stress distribution and the piston and liner matching.
