Dynamic analysis for main mechanism of 3-RRC multi-DIM vibration absorber

A new method for dynamic analysis of parallel mechanism is presented,which combines(d′Alembert) principle with principles of virtual displacements.Explicit expression of inertia forces of all parts are obtained by using d′Alembert principle.Based on principles of virtual displacements,driving forces of the parallel mechanism are obtained using the first influence coefficients.The theoretical calculation verified the correctness of the dynamic model.By using ADAMS simulation,it shows that the method is very practical and effective.multi-DIM vibration absorber;parallel mechanism;dynamics;d′Alembert principle;principles of virtual displacements
