基于ADAMS的伸缩臂叉装车工作装置运动学与动力学仿真

ADAMS-based kinematics and dynamics simulation for working device of telescopic boom fork truck

以伸缩臂叉装车的工作装置——伸缩臂为研究对象,建立了其ADAMS仿真模型。在不同伸缩长度、不同承载条件下,对变幅机构进行了运动学与动力学特性仿真。在最大负载、吊臂处于不同变幅角度条件下,对属具调平机构进行了动力学特性仿真。在吊臂处于水平、承载1 500 kg负载状态下进行了伸缩机构动力学仿真。得出了伸缩臂叉装车工作装置各部件的运动规律以及关键部件和关键受力位置的受力变化规律,对伸缩臂叉车的设计和优化具有重要的参考价值。

With the working device of telescopic boom fork truck -telescopic boom as a study object , ADAMS simu-lation model is built.Under the condition of different expansions and different loads , the kinematics and dynamics simula-tion is performed for the luffing mechanism.In case of maximum load , when the suspended arm is in different luffing an-gles, the dynamic characteristic simulation is performed for the luffing mechanism ; under the condition of the suspended arm in horizontal condition , the dynamic simulation is performed for expansion mechanism under 1500 kg-loading state.The movement rules of each part of working device of telescopic boom fork truck , and force change rules of critical parts and forced positions are worked out , which can provide significant value for design and optimization of telescopic boom fork truck.
