Abstract: The function of the towed road sweeper is suitable for the cleaning operation conditions of the road outside the city, and it has good maneuverability and obvious energy saving effect. The roller brush system with mechanical step-variable speed and hydraulic stepless speed regulation is taken as the research object. The brushing trajectory simulation and cleaning ability simulation of the roller brushing were carried out based on ADAMS. Through orthogonal experiment, the influence rule of the movement trajectory of garbage particles i...
