摘　　要：为现代化密植果园设计一款体积小巧、动作灵活、成本低廉的除草底盘结构.在介绍该底盘的整体结构和工作原理的基础上,设计了可自动升降的变割草高度机构;对底盘的转向性能、稳定性能和越障性能进行理论分析计算,使用有限元技术对底盘主体支撑框架进行分析仿真.分析结果表明:在满载四轮着地状态下,最大变形发生在支撑框架中间,共振发生起始频率为67 Hz;底盘可实现多种转弯半径转向和原地转向,最大越障高度为40.5 mm,可以在38°的坡面上稳定工作,具有实际场景应用价值.A small,flexible and low-cost mowing chassis structure has been designed for the modern orchard which adapts to mechanization and high density planting.The overall structure and working principle of the chassis are introduced,and a variable cutting height mechanism that can automatically rise and fall is designed;the steering performance,stability performance and obstacle crossing performance of the chassis are analyzed and calculated,and the finite element technology is used to carry out the main chassis frame.The analysis and simulation results show that the maximum deformation occurs in the middle of the frame when the four wheels are fully loaded on the ground,and the resonance frequency is 67 Hz;the chassis can realize multiple turning radius steering and in-situ steering functions,and the maximum obstacle crossing height is 40.5 mm,and the structure can work stably on a slope of 38°,which is of application value.
