摘　　要：为实现升降装置升起时使其中的顶架杆达到期望位置,课题组提出了一种针对升降装置的多连杆机构。基于解析几何法对多连杆机构进行运动学描述;利用四连杆解析法对多连杆机构进行优化设计,建立了其顶架杆运动方程;在此基础上,依据MATLAB与SolidWorks,进行了运动学方程求解与建模仿真,将运动学方程求解与建模仿真进行对照。结果表明:该装置升起后,其顶架杆达到期望位置,验证了运动方程的正确性。多连杆机构解决了升降装置实现期望位置的问题。In order to achieve the desired position of the top fame rod when the lifing device is lifted,a multi-link mechanism for the lifting device was proposed.Based on the analytic geometry method,the kinematics of the multi-link mechanism was described.The four-link analytical method was used to optimize the design of the multi-link mechanism,and the kinematics equation of the top frame rd was established.On this basis,according to MATLAB and SolidWorks,the kinematics equation solution and modeling simulation were carried out,and the kinematics equation solution and modeling simu lation were compared.The results show that after the device is lifted,the top frame rod reaches the desired position,which verifies the correctness of the kinematics equation.The multi-link mechanism solves the problem that the lifting device can achieve the desired position.
