建立了汽车变速箱轴系和齿轮的有限元分析网格模型.基于热网络法求出变速箱在实际工况下各节点的稳态温升来确定边界条件,获得了轴系和齿轮的温度场分布状况,从而根据实际工况对齿轮装置从整体到局部的热分布作了详细的描述.
The finite element analysis grid model of automobile transmission shaft and gear is established. Based on the thermal network method, the steady-state temperature rise of each node of the gearbox under actual operating conditions is obtained to determine the boundary conditions, and the temperature field distribution of the shaft system and the gear is obtained. According to the actual operating conditions, the gear unit from the whole to the part The heat distribution is described in detail.
