Abstract:

The slider-crank mechanism is a transmission mechanism extensively used in engineering practice. It is necessary to use the control system for getting a satisfactory trajectory. So the mechanism design is composed of two parts, structural design and control design. These two parts impact each other and are tightly coupled, and the separate design can not obtain the best performance. Hence integrated design is imperative. By making use of the Lyapunov function, an integrated design considering stability is proposed in this paper, seeing that stability is the most basic requirements of a closed-loop system. Simulation results show that this method can effectively carry out the mechanism design, reduce the body weight, optimize mechanism performance and save the design cost simultaneously.

Key words: slider-crank mechanism, structure system, control system, stability, integrated design
