有限元法用于缸套振动问题的研究

Application of Finite Element Method to Diesel Engine Cylinder Liner Vibration

本文讨论了用有限元法计算缸套振动的方法,并以12V180ZL 高速柴油机缸套为例,对缸套的自由振动、活塞横向冲击引起的缸套强迫振动、以及缸套壁厚和活塞横向冲击力的大小对缸套强迫振动的影响等方面进行了计算分析。本文的实际工作证明有限元法是研究缸套振动的一种有效方法,本文给出的计算结果对分析180柴油机缸套穴蚀有一定参考价值。

The free vibration of Type 12V180ZL engine cylinder liner and itsforced vibration c(?)used by piston clap ware calculated by use of finiteelement method,and the effects of liner thickness and piston clap force onliner vibration are discussed.It is proved that the finite element methodis effective for investigating liner vibration and the results obtained areapplicable for analyzing the liner cavitation of Type 180 diesel engine.
