Numerical Computation and Analysis for Temperature Field of Track Propulsion Device of Tank

为掌握坦克履带行驶装置的温度状况,建立了三维温度场数学模型,应用ANSYS软件进行了有限元数值计算,得到了负重轮、主动轮、诱导轮和履带环的详细温度分布。研究了坦克行驶速度、外界环境温度、太阳辐射能量、地面状况和坦克载荷等因素对负重轮温度的影响,敏感性分析显示坦克载荷的影响最大,地面状况的影响最小。研制了负重轮温度实车测试系统并进行了试验,有限元计算结果与试验值符合较好。

For grasping the temperature status of track propulsion device of tank, the mathematical model for 3-D temperature field was constructed, the FEA computation was carried out by ANSYS software to obtain the detailedtemperature distributions for road wheels, drive wheels, idle wheels and track. The effects of tank speed, environment temperature, sun radiant energy, ground status and tank load on temperature of road wheels were studied, the sensitivity of road wheel temperature was analyzed. The results show that the effect of tank load on the sensitivity is most, and the effect of ground status on it is least. The temperature testing system for road wheel of practical tank was developed, in which the experiment was implemented. The computed results accord well with the experimental values.
