Kinematics Analysis and Parameter Optimization of a Hybrid Input Mechanical Press

Abstract

Abstract:

This paper established the principles of hybrid input mechanism. Kinematic analysis on the mechanism was carried out under the condition of the given law of output. The variation laws of position,speed and acceleration of auxiliary driven were obtained. The simulation analysis and parameter optimization of this mechanism were completed with the aid of ADAMS parametric module，thus the kinematic performance of this mechanism is improved，and the quality of parts and life of dies are improved too.Then a reference basis is provided for the applications in engineering project of hybrid input mechanical press.

Key words: hybrid input, press, kinematics, ADAMS, parameter optimization
