Kinematics Simulation and Mechanical Analysis of Rotary Multi-Directional Combination Mechanism

针对一种可旋转架设门桥的新型多向组合连接装置,基于Solidworks软件构架机构的模型,进行了旋转架设机构的运动学与力学仿真。对不同架设速度下架设机构的速度-时间关系、加速度-时间关系进行了探究和对旋转架设期间几种典型情况下旋转架设机构的受力情况进行了计算和分析,发现旋转架设时间的选定对旋转油缸有较大影响。运动仿真结果表明,旋转组合机构能按照预定轨迹进行门桥架设且可满足门桥结构功能要求。

Aiming at a new type of multi-directional combined connection device for rotating portal bridge,kinematics and mechanics simulation of the rotating mechanism were carried out based on the model of Solidworks software framework mechanism.Emphasis was laid on exploring the velocity-time relationship and acceleration-time relationship of the erection mechanism under different erecting speeds,and calculating and analyzing the stress of the rotating erecting mechanism under several typical conditions during the erecting period.It is found that the selection of rotating erection time has a great influence on the rotating cylinder.The simulation results show that according to the predetermined trajectory,the portal bridge can be erected by the rotating combination mechanism,and the functional requirements of the portal bridge structure can be fulfilled.
