Simulation Analysis of Rolling Brush Performance of Towed Road Sweeper Based on ADAMS

摘要: 拖曳式公路清扫机的功能适应了城区外公路的清扫作业工况，且机动性好、节能效果明显。本文以可进行机械有级变速及液压无级调速的滚刷系统为研究对象，基于ADAMS进行了刷苗轨迹仿真及清扫能力仿真。通过正交试验，揭示了滚刷转速、作业行驶车速及滚刷中心离地高度三个工作参数对垃圾颗粒运动轨迹的影响规律，优选出了各作业行驶车速下的参数组合，为变工况条件下的作业标准化、工程精准化提供了控制策略。

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 is revealed by three working parameters including rolling brush speed, working speed and height of roller brushing center, and the parameter combinations under the driving speed of each operation are selected, providing the control strategy for standardization and energy precision under the variable working condition.
