链式挖沟机挖沟器的动态特性研究

Study on the dynamic characteristics for trenching implement of chain-type trencher

根据链式挖沟机挖沟器的结构和工作原理,利用ADAMS/Engine模块建立了挖沟器的虚拟样机模型。利用该模型对其动态特性进行了仿真分析,得出链齿在工作过程中受到的张紧力和碰撞力变化情况,同时获得了各链轮轴承处受到的冲击力以及驱动链轮需要的驱动力矩。为挖沟器的设计奠定了理论依据。

According to the structure and working principle of trenching implement of chain- type trencher, the virtual prototype of trenching implement is established using software ADAMS/Engine, and the simulation is also processed. The curve of intension force and impact force of chain is drawn during working process of the trenching implement, while it is drawn the curve of impact force acted on every chain wheel and the driving moment of the driving wheel is calculated. It established the theoretical base for the design of trenching implement.
