基于RecurDyn的丘陵作业平台坡地稳定性研究
Research on Slope Stability of Hilly Work Platform Based on RecurDyn
摘要
Abstract
This paper studied the slope stability of a centroid-adjustable working platform to address the issue of poor sta-bility and tipping of agricultural machinery during operations on hilly terrain.The working platform needed to lift and low-er its working device according to the operational requirements.However,when the working device had a significant mass,it greatly affects the stability on slope,leading to tipping during longitudinal and lateral driving and obstacle cross-ing.This study established stability analysis models for conventional longitudinal and lateral driving and obstacle-crossing under different working conditions of the working platform.The study also analyzed the adjustment capability of the centroid-adjustment device on the stability of the whole machine during longitudinal and transverse driving and obstacle crossing.The theoretical analysis was validated through a combination of Recurdyn preliminary simulations and compre-hensive experimental analysis using a test platform.The experimental results on the test platform indicated that by adjus-ting the position of the working device reasonably,the maximum slope angle of the working platform in different working conditions could be increased by approximately 6°.The maximum obstacle crossing height during longitudinal and lateral driving on a common 15° slope was increased by approximately 40 mm and 120 mm,respectively,significantly enhanced the stability of slope driving.This verified the usability of the stability analysis models and provided theoretical references for the design of working platforms in hilly regions.关键词
