The Structural Optimal Design And Motion Characteristic Analysis Of The Buffer Damping-Vibration Over-loading Security Clutch

The Buffer Damping-vibration Over-loading Security Clutch is a new kind of steel ball security clutch. It has the characteristics of less contact-impact, damp vibration, powerful transmitting torque, small volume, high load bearing capacity , combining and separating rapidly, automatic protective when over loading and so on, so it has a good application prospect. Base on the fully understanding and analysis of structural characteristics and working principle of security clutch, this paper according to the need of corporation and combine actual topic, using MATLAB software to carry on the modern optimization design for security clutch. Then, the clutch after the optimization design is carried out the assemblage and simulation of virtual prototype in use of ADAMS software and study and analysis of the motion characteristics.In the structure optimization of security clutch: First, according to the structure characteristics of the clutch and the working process, find out the mechanical relation between structures and established mechanics model of the clutch. Then base on the optimization function format of MATLAB optimal toolbox, establish the optimization mathematics model that the optimization object is the size of clutch is minimize and meet the key performance requirements of the clutch, compile the optimization procedures to optimize and obtain main dimensions of the clutch after optimizing .In the virtual simulation of the security clutch: First,according to the main dimensions of clutch after optimizing the clutch , establish CAD model in the UG modeling environment. And then exchanged by ADAMS graphical interfaces into ADAMS software, set the system environment parameters and add constraints. Finally, the virtual prototype of security clutch is simulated in the rated load movement and in the overload protection movement , obtain important parameter curves and important parameter.
