摘要
车辆差速器锁止机构自动控制系统(Vehicle Differential Lock System,VDLS)提高了越野汽车在坏路及无路情况下的地面通过性,阐述了VDLS关键部件套合器(Dogclutch)的工作原理、结构特点和设计方法;并运用Pro/E和ANSYS联合建模技术,建立了套合器的三维有限元模型,对套合器进行应力分析,计算得到套合器的应力及应变,并能够准确地揭示受力状态和最大应力发生部位,为套合器齿形设计和强度计算提供了可靠的依据。
The vehicle differential lock system improves the vehicles’Toff-road capability.It present the operation principle,structure characteristic and devise method of the key component dog clutch for VDLS,A 3-D finite element model of the dog clutch is developed with the commercial software of Pro/E and ANSYS.It is aimed at the strain analysis of the dog clutch With the finite element analysis（FEA）.The computations and analyses show the stress distribution and the place of the most stress.The results of FEA will provide a valuable reference for the structure design and the strength calculation in future research.
