Optimistic experiment methods of dimension synthesis of plane four-bar mechanism;

The Research of a Spatial Rolling-walk Mobile Mechanism Based on Four-bar Mechanism;

The ant colony algorithm was used to carry on optimization design of four-bar mechanism for food machinery,analyzing and building the geometric relation between the linkage.

Optimization of four-rod mechanism based on fuzzy set theory;

By way of analyzing the action mechanism of toys which can walk by two or four foots,the characteristics and points for attention in design of four-rod mechanisms were expounded.

On the condition that the axes of two chain wheels are in the same horizontal plane, the paper considers that the mesh drive of chain and chain wheel is equal to single small angle movement of four-rod mechanism every time on tight side.

Analysis on influence of synthetic accuracy for track of four-bar linkage affected by manufacturing error;

Research on dynamic behavior of flexible four-bar linkage;

The vibration test of finishing lapping machine for ball bearing outer race shows that vibration becomes more and more serious with the increasing of rotation speed of crank,which is excited by four-bar linkage.

The paper gives a example to show a new method of analysis and design of four bar linkage using the popular software,Microsoft Excel,which can perform mumerical calculations and creating charts quickly and accurately It shows the new method makes the analysis and design more understandable,simple and accurate In particular,needn t make any program will raise the designer s productivity highl

An application example, in which the varible length four bar linkage is used in beam pumping unit s design, is given to demonstrate the practical effect.

The singular positions of planar four bar linkage with special sizes are analyzed.

This paper presents the special application to half-angle rotating method,which belongs to four bar mechanism synthesis method,in the design of wraping execute mechanism.

If the connecting rods locating length and four kinematic positions are known,the optimum design of plane four bar mechanism can be made by the optimization methods.

In the design process of plane four bar mechanism, because the traditional method could generate low accuracy and low efficiency,we use Bee Evolutionary Genetic Algorithm to take the place of traditional graphical method or analytic method.
