Elastic Dynamic Modeling And Simulation Of The Motor-Elastic Linkage Mechanism System With Links Fabricated From Composite Materials

The development of mechanology has a close connection with the invention and application of new materials, and the research on the application of new materials is very important in the domain of modern mechanology. It is one of the valid strategies improving the elastodynamic properties of mechanical systems to exploit the high strength-to-weight ratios and damping properties of advanced composite materials that are superior to the conventional metals. However, some exceptional phenomena often emerge in the operation of these high-speed mechanisms with links fabricated from advanced composite materials, and sometimes the malfunctions are serious. For example, these high-speed and light-mass mechanism produce intense vibration caused by magnetic resonance of the driving motor, critical speed of the system may varies with the circulation parameter of the electromotor, and so on. The main reason is that the dynamic properties of the mechanism with links fabricated from composite materials still have not been studied deeply.Since 1980, people have begun to research the problems that composite laminates were applied into mechanisms. And then, the mechanisms with links fabricated from composite laminates have been applied gradually into many fields such as high-speed production lines and the industrial robots, and it is shown that these mechanisms have some advantages in engineering practice such as lightweight and short residual vibration's time. However, when people established the model of these kinds of mechanisms, the dynamic analytic model...
