%X 为了降低活塞的表面温度，提高活塞结构的质量以及耐久性能，本文以船用柴油机CZ380活塞作为研究对象，对活塞进行尺寸计算以及确定活塞的温度、换热条件。再通过CATIA软件建立活塞三维模型，分析活塞的结构和材料等因素对活塞温度场、变形的影响，从而对活塞的结构进行改进。本文的仿真结果较为合理地反映了柴油机稳态工作的情况。对柴油机活塞的分析优化，为进一步的研究提供了有力的指导意义。<br />
In order to lower the surface temperature of the piston and improve the quality and durability of its structure, this paper takes the piston of marine diesel engine CZ380 as the research object. Thus the temperature and heat transfer conditions of the piston can be finally determined after measuring the piston size. Then, a three-dimensional model of the piston is established in CATIA software to analyze the influence of the structure and material of the piston on the temperature field and deformation, so as to improve the structure of the piston. The simulation results in this paper reflect the steady state operation of diesel engine reasonably. The analysis and optimization of diesel engine piston provides strong guiding significance for the research of diesel engine piston.
