摘　　要：小型履带式搬运车工作装置是一种由约束双平行四杆机构构成的装置,该工作装置可保证装卸过程中货物始终保持平动,使工作安全可靠。由于工作装置由两个平行四杆机构串联组成,利用导轨约束其运动轨迹,机构受力复杂。采用静力学方法,对工作装置进行了受力分析,建立主臂液压缸和举升臂液压缸力学方程,基于MATLAB编程分别对自装卸过程的主臂液压缸和举升过程的举升臂液压缸的力学性能进行了仿真分析。研究内容为该类型工作装置设计提供了理论基础。How a reach handler is stressed and analyzed.Dual parallelism is used in the operational system of the compact crawler type reach handler that the parallelism system is mutually restricted and has to be rectified to keep a stable and reliable handling operation.Therefore,we had to utilize static processes to formulate mechanical equations for the boom cylinders and the lift arm cylinders so as to stress analyze the working attachment before simulation analyses of mechanical functions of the cylinders during their operation.What we have done in our study can be a theoretical basis for design of similar handling attachments.
