摘　　要：为了对粘性限滑差速器的工作原理及其对车辆性能的影响有深入了解,在建立的限滑差速器剪切转矩传递模型的基础上,以7自由度整车模型为例,进行汽车装粘性限滑差速器与装普通差速器的操纵稳定性对比分析。仿真结果表明,限滑差速器不仅能有效改善车辆的操纵稳定性,还可以明显提高车辆的动力性和通过性。In order to in-depth understand the work mechanism of viscous limited-slip differential and its influence to vehicle performances,based on the establishment of limited-slip differential torque transfer model and take 7 degrees of freedom vehicle model as an example,the comparative analysis of vehicles installed with viscous limited-slip differential or ordinary differential have been done.The simulation results show that,limited-slip differential can not only effectively improve vehicle handling and stability,but also significantly improve vehicle power performance and traffic ability.
