Dynamics Models and Transmission Performances of a Crank Slide-Way Mechanism

A crank slide-way mechanism is a kind of mechanisms between crank slide mechanisms and crank rocker mechanisms, the main difference is that: in the same case of taking uniform speed as input, the output is neither linear displacement nor the arc path, but a specifically curve. So in some cases, A complex output path can be realized when kinematical curves with special shapes have been accepted. The kinematics and dynamics mathematical models based on closed loop vector equations and Newtonian mechanics principles are established in terms of structural forms and characteristics of the crank slide-way mechanism. A new simulation method for the kinematics and dynamics of the crank slide-way mechanism is put forward. Driving moments and restrained forces at different positions in one period have been indicated in the case of simulation to a real structure. Compared to the existing discrete point analysis, the method is very feasible and efficient due to its characteristics such that strict solve progress, less workload and high precision. It provides a useful feasible measurement for carrying out kinematics and dynamics characteristics of mechanisms like this; similarly it can be applied to other kinds of relevant rod mechanisms.
