Study of CAD/CAE/CAM-based design method for crank-connecting rod mechanism

Based on CAD/CAM/CAE technology, the design method and process for crank-connecting rod mechanism are discussed in this paper. First, the crank-connecting rod mechanism is modeled and virtual assembled to establish a model. Then, using the virtual assembling model, the kinematics and dynamics simulation is completed and the analysis results is used to complete finite element analysis of the connecting rod. Finally, NC manufacture simulating of connecting rod is done. The result show that by use of CAD/CAE/CAM technology of the crank-connecting rod mechanism, the development period can be shorten and the cost for the development can be cut down.
