Analysis And Synthesis For Hybrid Input Five-bar Mechanism

In this paper, take the hybrid input five-bar mechanism for double crank based on link-rack ram and linkage as subject investigated. This research is mainly around this mechanism. Research content is focused on the followings.Firstly, set out from the assembly conditions, the mobility of this mechanism was analyzed, the existence condition of this mechanism was determined.Secondly, by analyzing the conditions of singularity, this paper conclude the styles of existing the two kinds of singularity.Thirdly, analyse based on forward kinematics and inverse kinematics, some examples verify the existence of the mechanism and the correctness of formula deduction.Finally, this paper presents the optimal synthesis of crank-linkage mechanism. Regard two different style as the goal, set up different optimal synthesis model on the base of forward kinematics and inverse kinematics analyses. Offered the theory method for the optimal shnthesis of hybrid-driven and controlled mechanism. The results of optimal synthesis examples verifies the institution performance have a great improvement after optimization.
