坦克液力机械传动装置热分析

摘要

综合考虑液力机械传动装置中各系统间相互作用以及润滑油,动力舱空气和车体对传热的影响,建立了坦克液力机械传动装置的整体热分析模型.模型由传动箱、液力变矩器、变速器、侧减速器的产热模型和热网络传热模型组成.对坦克机械传动工况和液力传动工况进行了热分析,得到了传动装置产热量、传热量和部件温度的详细分布.给出了温度分析值与试验值的对比.结果表明.热分析温度值与实车行驶测试值对比最大相对误差小于10%.%Considering comprehensively interference among the components in hydrodynamic mechanical transmission and influences of lubricating oil,the air in powerplant compartment and hull on the transfered heat,a whole thermal analysis model was established,which consists of the generated heat models and the transfered heat model of the components such as gearbox,hydrodynamic torque converter,transmission and final gearbox.The thermal analysis was accomplished for tank mechanical drive and hydraulic drive work conditions,and heat generation quantity and heat transfer quantity for transmission device and detailed temperature distribution for components were obtained.The comparison between the analyzed and the tested temperature values was carried out.The analyzed results show that the maximum relative error of temperatures between the thermo-analyzed and the tested is less than 10%.
