Abstract For the current situation of difficulty in dismantling heavy wheel and the complexity of existing dismounting machine， a pendulum rod removable device for heavy wheel was designed. The structural concept and working principle were introduced; the method of geometric analysis was used to determine the four limiting locations of the wheel center; kinematics simulation of the device was taken in Pro/Engineer software， the track area of wheel center was achieved， and the respective impact of the pendulum rod length and two sidebracket on the track area were analyzed， also， the ratio of left-right span to up-down span of the track area were defined when the adjustment range of device was optimal. It is indicated that device has many characteristics through on-site applications， such as high rate for centering， convenient to dismounting， stability， safe and reliable， and easy for vehicle carrying and field using．

摆杆式重型车轮拆装装置的设计与动态仿真
针对重型车轮拆装困难和现有拆装机械复杂的现状，设计了一种摆杆式重型车轮拆装装置.介绍了其结构方案和工作原理；利用几何分析法，确定了车轮中心的4个极限位置；利用Pro/E软件进行了运动学仿真，得到了车轮中心的轨迹区域，并分别分析了装置的摆杆长和侧支架间距对轨迹区域的影响，确定了装置在最佳调整范围时，轨迹区域左右跨度和上下跨度的比值.通过现场应用，表明装置具有对中率高、拆装方便、稳定性强、安全可靠、便于车载和野外使用的特点.
