| 摘 要： | 研究活塞冷却油腔位置改变对活塞温度场的影响.采用Pro/E软件建立德国1015型柴油机活塞的有限元模型(FEM).在性能计算的基础上确定了活塞顶等部位的热边界条件.利用ANSYS软件研究活塞振荡冷却油腔位置改变后,活塞各关键部位温度的变化规律及其对冷却油腔位置的敏感程度.结果表明,冷却油腔位置对活塞各部位温度的影响规律有较大的差别.冷却油腔位置改变对活塞第一环槽影响最大,不仅温度的变化速度有极值点,而且通过移动冷却油腔可以使第一环槽的温度降低约30℃.

| Abstract: | Studies the effect upon piston temperature field from changes in positions of the cooling gallery.A FEM piston model for a model 1015 engine was developed on Pro/E and thermal simulations achieved through ANSYS.Rigorous simulations were performed to find the temperature change rules and the sensitivity of piston temperature field with regard to the cooling gallery position.The results demonstrated that the position of cooling gallery has various effects upon the piston temperature.The temperature of top-ring groove can be reduced by 30 degree centigrade by moving the cooling gallery upward.The velocity of temperature change in the top-ring groove attained a global maximum. |
