In order to solve the most commonly used classic problem of the inclined conveyor belt in our daily life, we provide an effective correlation algorithm. The shortcut fang'b inclined conveyor belt model generally includes two problems: 1. Dynamics problem (involving multi-process variable speed movement); 2. Energy problems. Compulsory 1 covers only the first question. We regard the friction between the object and the conveyor belt as an internal force, and according to whether the object is subjected to external force, it can be divided into transmission without external force and conveyor belt with external force.
