Abstract

According to working principle of the deploying and retracing mast, this paper presents that the mast needs to be stiffened by a root stiffness mechanism. The double-slider mechanism with a spring is designed as the root stiffness mechanism. Then motion of the root stiffness mechanism is studied to set up vibrating equation of slider 2 based on the Lagrange equation. Displacement and velocity expression of slider 2 are obtained. At last, the Matlab program is used to check correctness of theory analysis. Elastic coefficient of spring and length of bars are selected by the program.
