In view of the poor selfpropelled ability of the safflower picking mobile platform and the tilting of the position when working on uneven field ground, a safflower picking mobile platform was designed, and the overall performance of the mobile platform was analyzed theoretically to determine the rationality of the structural design of the mobile platform. The displacement and equivalent force of the mobile platform under bending and torsion conditions were simulated by ANSYS static analysis, the maximum deformation of the mobile platform was 2.95mm, which occured at the right rear wheel position of the mobile platform, the maximum stress was 235.8 MPa, which occurred at the rear wheel frame connection position, the overall displacement and strain was small, and the mobile platform structure met the requirements. The obstacle crossing and climbing performance test of the designed mobile platform was carried out, and the test results showed that the designed mobile platform could start smoothly and keep a certain speed to walk at a constant speed with good power performance, the ultimate overrun height was 61.2mm, the longitudinal ultimate tipping angle was equal to 19.7°, and the transverse ultimate tipping angle was 18.3°. The designed mobile platform has a good structure and performance, which can provide a comprehensive application platform for safflower picking machinery and can provide support for subsequent field trials.

针对红花采摘移动平台自走能力差，在不平整田间地面工作时位姿发生倾斜等问题，设计一种红花采摘移动平台，并对移动平台的整体性能进行理论分析，确定移动平台结构设计的合理性。通过ANSYS静力学分析模拟移动平台在弯曲、扭转工况下的位移量和等效应力，得到移动平台最大变形量为2.95 mm，发生在移动平台的右后轮位置；最大应力为235.8 MPa，发生在后轮车架连接位置；整体位移量和应变较小，移动平台结构满足要求。对设计的移动平台进行越障与爬坡性能试验，试验结果表明：移动平台可以顺利启动并保持一定速度匀速行走，动力性能良好，极限越障高度为61.2 mm，纵向极限倾翻角等于19.7°，横向极限倾翻角为18.3°。设计的移动平台具有较好的结构和性能，可为红花采摘作业机械提供综合应用平台并可为后续的实地田间试验提供支撑。
