Abstract


With the construction of cities and the increase in highway mileage in China, sweeper is playing an increasingly important role. The rear rolling drum-type sweeper have been independent research and development in recent years, which is aim at the mechanical sweepers that had been used a wide range in the domestic market. It greatly improved the cleaning performance of the mechanical sweeper. Compared with Vacuum Sweeper, the rear rolling drum-type sweeper is more suitable for actual road conditions in the domestic, and has the advantages of a simple structure and low energy consumption. It is in line with national policies of energy saving and has important research significance.In this paper, the working device of Rear Rolling Drum-Type Sweeper was analyzed and simulated. The movement of waste particles was researched in the working process. Firstly, theoretical model of waste particle trajectories was established in the working process of the working device, and was programmed by using MATLAB software. The trajectory theory of waste particle was simulated and optimized by changing the parameters. Next, simplified solid model of the working device was build with UG software. Finally, the solid model was loaded into ADAMS, and the flexible features of brush of the working device was considered, the virtual prototype model of flexible coupling of the working device was established by using ADAMS to simulate. The trajectory of waste particle and the contact with the components was analyzed during movement. It further verified the correctness of the theoretical model.Through theoretical analysis, the main parameters affect the cleaning performance was achieved. The vehicle cleaning performance depends on the ratio of vehicle driving speed and roller rotation speed. Trajectory of waste particles is related to maximum deformation of brush, the separation angle between the Front bezel and the ground, upload angle of under brush and throw angle of upper brush. A part of the main parameters were validated by the simulation research. The main parameters on cleaning performance was further confirmed.
