| The main topic of this paper'is research the relationship between crank-rocker mechanism performance parameters and institutional dimensions, draws mechanical properties mutuality map, analyze relationship between mechanism properties parameters and mechanical body size, summarize the mechanical body size and parameters performance the design rule. Planar pivot four-bar mechanism is widely used in century project. Planar pivot four-bar mechanism is the base of planar multi-bar linkage, so planar pivot four-bar mechanism's Design Research is very important.This thesis through establishing the planar linkage assembly, instead of using the relative dimension of the actual dimension, which simplifies the dimension of type, establish the full dimension plane four-bar linkage type and spatial points of the correspondence.There always get a range use mutuality map analysis, to solve practical problems, to meet the practical needs, and makes the design dimension bar work performance, the article adopt analysis constraint functions, establish multi-objective function of the mathematical model, According to different working conditions on the four-bar linkage of the mechanical performance requirements of different focus, adjust the weighting factors control values, make the sub-objective function have important varying degrees, to achieve the optimized design results, and get the final design.There always get a range use mutuality map analysis, to solve practical problems, to meet the practical needs, and makes the design dimension bar work performance, the article adopt analysis constraint functions, establish multi-objective function of the mathematical model, According to different working conditions on the four-bar linkage of the mechanical performance requirements of different focus, adjust the weighting factors control values, make the sub-objective function have important varying degrees. |
