The Dynamic Optimization and a New Structure of the Nursing Bed Robot

Abstract:

In line with the principle of ergonomics and mechanism and based on bar linkage ,this thesis puts forward a nursing bed robot with the introduction of its structure and working principle. According to the many-body system dynamics theory and by the application of the simulation software ADAMS of mechanical system dynamics ,we first set up the pattern of the virtual model machine which posses a nursing bed with the combined linkage of sitting up straight with its knees bent. And second we successfully optimized the dimensions of the structural parts of the nursing bed robot by realizing the design goal of minimizing the maxi force intensity borne by the linear motor .Finally following the result of optimization and the optimal scheme which satisfies the design requirements, we made the model machine of the nursing bed robot.
