Kinematic Analysis of Dual-elbow-bar Mechanism Using Vector Representation and Optimization

This paper presents a kinematic model for the dual-elbow-bar mechanism by using the vector representation.With the proposed model,the kinematic expression of the discussed mechanism is derived and a simulation is conducted by Matlab codes.The perfect match between the simulation results and the ADAMS results proves the validation of the kinematic model.The simulation results also reveal that the moving platform works in an oscillating movement.An optimization model is presented on the bases of kinematic analysis.The whirling angle of the moving platform of the mechanism is dedicatedly chosen as the objective function and the linkage lengths as the variables.By simulation results reveal that after the optimization,the performance of mechanism is improved.
