In view of the disadvantages of the present modeling methods for parachutes (suspension) systems, a novel method based on static equilibrium of the middle points is presented.

Analyses reason that suspension system of electrical vibration convey coal machine is breaked under cleek coal store, changes suspension system into supporting system, that dispel effect of sector.

The model is comprised of the general rigid-body equations considering apparent mass and the modeling method of suspension system based on the assumption of "equilibrium points".
