Through comparison and analyses, literature information and characteristics tracks and exten sions of sweep arm and direct arm smasling were discussed.

Optimization design on the pulling arm system of garbage transportation vehicle based on ADAMS;

Taking the big arm of excavator working device as an example,the 3D model of working mechanism was established by CAE software Pro/E,then using finite element analysis software ANSYS to analyze the stiffness,strength of working equipment.

Dynamic Analysis of Hooklift Working Device Based on Virtual Prototype

The calculation result shows that the campari son with common hooklift,not only the pressure of hydraulic cylinder but also th e tilting angle of container of Rotating Hooklift is reduced,the synthetical cap ability is improved greatly.

Rotating hooklift is a large-capacity garbage truck,in this paper mathematical model is established and optimization is used firstly, in which the maximal force and the smooth movement of the mechanism are used as objective function for it to improve its capability.
