Virtual Prototype Design Of Grab Excavating Equipment

As for Wuliansuhai lake's features , it has great significance to mine sediments for delaying marsh, 3D model software Pro/E and dynamic analysis software ADAMS were used for developing the virtual prototype design of excavator. The structural size of grab was optimized by using the penalty function, parameter model and finite element analysis were conducted for optimized grab by using Pro/E, the actual movement of grab when working have been simulated and interference test has been done after assembling their components. Using special connection Mechanism/Pro between Pro/E and ADAM, Pro/E 3D model has been transferred directly into ADAMS to avoid data loss by the "seamless link" technology , the unit, density, rigid body and option of transforming have been solved when model was transferred. Real movement has been imitated after adding complicated constraints, load, friction. The opening angle curve of the open struggle,pressure changes curve of the hydraulic cylinder,pressure changes curve of the main hydraulic cylinder, which provide a theoretical basis for the design and manufacture have been analyzed and mapped out by ADAMS/processor.
