Abstract


The main subject of crank rocker mechanism performance parameters and institutional dimensions related to map drawing mechanical properties , the relationship between the analysis of the mechanical properties of parameters and institutional dimensions , summed agency size and performance parameters , design rules . Four institutions plane hinge four institutions in engineering practice a wide range of applications, graphic plane multi - bar mechanism and space bar mechanism based on the design of the flat- four institutions has a very important significance . Planar linkage space model , instead of the actual size of the relative size , thus simplifying the size type , and to establish the corresponding relationship between the size of the four agencies of all plane - space point position . The size of the rod on pattern analysis often results in a range , to adapt to the real work to make the link design size performance ideal for solving practical problems, the paper uses the analysis of constraint functions , the establishment of a mathematical model for multi- objective function , according to the different conditions on the mechanical performance requirements of the crank-rocker mechanism different focus control to adjust the value of the weighting factor , the degree of importance of the objective function of each sub to achieve design optimization of the results , and draw the final design . The thesis describes how to draw the the parameter plane interval corresponding to the size of any agency relationship between the map and study the performance parameters of the crank-rocker mechanism and institutional dimensions , the parameter value of institutional types and parameters reasonable judgment problem and the establishment of a multi- objective function a mathematical model to achieve the optimization of the design results , design agencies design more convenient design results more in line with the actual work , the results of crank-rocker mechanism designed to provide a theoretical basis .
