摘要：

船用低速二冲程柴油机正不断向长冲程,高爆压,高自动化,高智能化,低能耗,低排放的方向发展.MAN公司为满足市场的新要求,研发设计了ME-B系列柴油机.活塞头作为柴油机内重要的部件之一,其热负荷一直是科研人员研究的重点.ME-B系列柴油机活塞头与以前型号的活塞头相比,结构,尺寸改变较大.使用ANSYS有限元分析软件,以最新型6S50ME-B柴油机活塞头为分析对象,在建立活塞头三维实体模型后求出活塞头在稳态工况下的温度场分布.以求得的温度场为边界条件,求出6S50ME-B活塞头的热应力场,找出活塞头的薄弱点,为进一步优化提供理论支持.

关键词: 柴油机, 活塞头, 温度场, 热应力场

Abstract:

The low speed two-stroke marine diesel engine is developing continuously towards long stroke, high pressure, high automation, high intelligence, low consumption and low emission. MAN Company designs new ME-B type diesel engine to meet these requirements. Piston crown are one of the most important components of the engine and thermal load analysis is always the focus of research. ME-B piston crown is modified significantly in structure and dimension compared with old design. Finite element analysis is carried out for piston crown of the latest 6S50ME-B diesel engine by using ANSYS software. The three-dimensional model of piston crown is established and the temperature field is obtained. Using the temperature field as the boundary conditions, the thermal stress field and the weak point on the piston crown are found, which may offer theoretical support for further optimization.

Key words: diesel engine, piston crown, temperature field, thermal stress field
