果园小型履带式底盘设计与仿真分析OA

In hilly orchard terrain characterized by narrow spaces and complex road conditions,small mobile equipment often faces problems of insufficient trafficability and poor stability.To address this demand,a small triangular tracked chassis suitable for orchard operations in the Sichuan-Chongqing region was proposed.Through mechanical analysis and parameter design of the key components,a compact layout scheme tailored to orchard application scenarios was constructed,and dynamic models for typical operating conditions such as slope climbing,vertical obstacle crossing,and ditch crossing were established.Multi-scenario simulation verifications were carried out in RecurDyn software on both soft soil and hard ground.The results showed that the chassis was able to maintain stable driving on a 30° slope,could surmount a vertical obstacle of approximately 130 mm,and was capable of crossing a ditch of about 400 mm;the variations in driving force and speed under different ground conditions exhibited good controllability and recoverability.The study indicates that this tracked chassis possesses strong terrain adaptability and can serve as a stable and reliable mobile platform foundation for automated orchard operation equipment.
