套缸式高空作业车摆臂机构机构综合分析

为选择机构的合理结构形式、运动副类型、数目及合理的尺寸搭配,对一种高空作业车摆臂机构进行分析.在已知连杆铰接点的起始位置、连架杆的对应转角及机架长度的平面综合连杆机构的各设计变量间关系的条件下,根据给定的运动学或动力学要求,进行了机构综合.对六杆运动链连杆类配方案进行选择,组合生成六连杆4种形式,在此基础上再生运动链,形成新的机构形式,给出机构多种可能的构型,完成摆臂机构的型综合.对不同方案进行比较,得出了满足运动学及动力学要求的最优解.

Mechanism analysis of the swing arm of telescopic cylindrical type aerial platform truck

To propose a rational construction,pair type,numbers and suitable size assortment,a kind of swing arm of an aerial platform truck was analyzed.The synthesis of mechanism was done to the starting position of connecting rod hinge point,corresponding corner of side links and length of the rack of the planar integrated linkage according to the kinematics or dynamics given requirements.The link combination types for six-bar linkage were selected and four combining forms were generated,then based on the forms,kinematic chain was regenerated and new mechanisms was produced,which gave a variety of possible configurations and completed the structural synthesis for the arm institution.The optimal solution is finally given after comparing the different schemes.
