建立了集装箱正面吊运机的MSC.ADAMS运动学分析模型,考虑了4种典型起吊位置和4种起吊载荷工况,得到了俯仰液压缸和伸缩液压缸随时间变化的位移、速度、加速度和受力曲线以及基本臂与车架体铰点的约束力随时间变化的仿真曲线,并与采用MSC.NASTRAN软件进行有限元计算的结果做了对比分析。相对误差在0.19%～8.88%之间,验证了ADAMS仿真结果的正确性。得出的结果可为集装箱正面吊运机的俯仰液压缸、伸缩液压缸以及臂架的设计提供理论依据。
The MSC.ADAMS kinematic analysis model of the frontal container hoisting machine is established. Considering four typical lifting positions and four lifting load conditions, the displacement, velocity and acceleration of the hydraulic cylinder and the telescopic cylinder over time are obtained Force curves and the simulation curves of the binding force of the hinge between the basic arm and the frame body over time were compared with the results of the finite element calculation using MSC.NASTRAN software. The relative error is between 0.19% and 8.88%, which verifies the correctness of ADAMS simulation results. The obtained results can provide the theoretical basis for the design of tilt cylinder, telescopic hydraulic cylinder and boom of the container front hoisting machine.
