Research on the Motion Reliability of Nursing Bed Mechanism Based on Response Surface Method

Abstract To study the analysis and optimization of motion reliability multifunctional nursing bed mechanism, ADAMS software platform was chosen to simulate parametric modeling with consideration dimensional clearance errors. Taking back-raising mechanism as an example, we verify accuracy model by comparing experimental data. Based on effect error, a response surface motor end hinge clearance, push rod back support pivot plate influencing factors angular velocity acceleration values, were established, significance values obtained using ANOVA. target each factor, simulation experiments conducted that error result method 1.64%. It shows prediction is more accurate feasible for analysis.
