摘　　要：为解决液力机械综合传动装置低温环境下的快速起动问题,需要对其在低温域的传动特性进行试验测试。进行了液力机械综合传动装置和单一旋转件在低温环境下的运行阻力矩特性测试和流场分析。研究结果表明:在特定温度段液力机械综合传动装置的运行阻力矩随转速的升高而降低,单一旋转件测试进一步验证了这一规律;对比不同温度下的流场发现,润滑油液的非牛顿流体特性在该规律中起主要作用。To address the challenge of fast starting of the hydro-mechanical comprehensive transmission device(HMCTD)in low temperature conditions,the transmission characteristics should be tested within a low-temperature range.This study focuses on the resistance torque characteristics of the HMCTD and a single rotating part,both subjected to low-temperature conditions,through running resistance torque characteristic test and flow field analysis.The results show that the resistance torque of the HMCTD decreases with increasing input rotating speed,which is further validated through the single rotating part test.By comparing the flow field at different temperatures,it is concluded that the non-Newtonian behavior of the oil plays a significant role.
