A hybrid five bar mechanism is a typical planar parallel robot. It is a configuration that combines the motions of two characteristically different motors by means of a five bar mechanism to produce programmable output. Hybrid five bar mechanism is the most representative one of hybrid mechanism. In this paper, considering the bond graph can provide a compact and versatile representation for kinematics and dynamics of hybrid mechanism, the dynamics analysis for a hybrid five-bar mechanism based on power bond graph theory is introduced. Then an optimization design of hybrid mechanism is performed with reference to dynamic objective function. By the use of the properties of global search of genetic algorithm (GA), an improved GA algorithm is proposed based on real-code. Optimum dimensions are obtained assuming there are no dimensional tolerances or clearances. Finally, a numerical example is carried out, and the simulation result shows that the optimization method is feasible and satisfactory in the design of hybrid mechanism.

Assessment Procedures

Dynamic response is an important criterion of quality for many hydraulic control systems. It is suggested that power flow modeling procedures, and in particular the recent development of power bond graph techniques, provide the designer-analyst of hydraulic control systems with a particularly relevant means for investigating dynamic performance as he designs a proposed system. The bond graph modeling technique followed by digital simulation of the model is applied to a hydraulic system proposed for a particular task. Predicted response and subsequently measured response are given, compared, and discussed. Only generally available data and parameter assessment procedures were used for the prediction.

It makes certain reference to the design of the hydraulic system in which the load changes large.
