摘要
在微机上对ＺＨ１１０５Ｗ型非对称柴油机活塞进行三维稳态温度场的有限元分析．规模为４９１１个节点、３４９８个８节点六面体等参元，通过调整活塞表面对流换热系数和环境温度的分布，使１２个测点温度与计算温度场中对应点温度差控制在一定范围内．调整的最后结果，拟合误差在１％以内．根据最后计算结果绘出不同截面的等温线，还进行了温度分布分析．
On a micro-computer the finite element analysis was made on 3-D temperaturefield of mode ZH1105W unsymmetrical diesel engine piston with 4 911 nodes and 3 498 8-nodehexahedron isoparametric elements. By modifying the convection coefficients and environmenttemperature, the difference between the measured values and calculated values of 12 points in thepiston boundary fit can be limited in a satisfied range. The final modified results show that thefitting error is lower than 1%. According to the final numerical results, the iso-temperature graphsof some sections were drawn.
