| 摘 要： | 针对我国目前山地甘蔗收割困难、缺乏适用收获装备的问题,设计了三角履带式甘蔗联合收割机转向系统,主要包括后桥、轮桥连接架的设计和转向油缸行程确定。针对关键部件转向后桥和轮桥连接架进行了受力计算与有限元应力分析,对转弯半径进行了计算,并进行了相应的试验。关键零件应力测试试验结果表明:转向后桥的最大静应力为43. 67MPa,动态稳定应力约50MPa,仿真误差为12. 66%;轮桥连接架转向最大静应力158.59 MPa,动态应力为176 MPa,仿真的误差为9. 89%,仿真与实际基本一致。转弯半径试验结果表明:理论转弯半径为6.4m,实际测试时由于车速不同,转弯半径在6.127～6.5m范围内,与理论最大误差4.27%,在可接受范围内,转向系统的设计达到了设计要求。

| Abstract: | In view of the difficulties in the harvesting of sugarcane in mountainous areas in China,the lack of the suitable harvest equipment,the steering system of the triangle track sugarcane combine harvester is designed.It mainly includes the rear axle,the wheel bridge connecting frame design and the steering oil cylinder stroke determination.The stress calculation and finite element stress analysis are carried out for the key components to the rear axle and the bridge connecting frame,and the turning radius is calculated and the corresponding experiment is carried out.The stress test results of the key parts show that the maximum static stress in the rear axle is 43.67MPa,the dynamic stability stress is about 50MPa,and the simulation error is 12.66%.The maximum static stress of the wheel bridge connecting frame is 158.59 MPa,the dynamic stress is 176MPa,the simulation error is 9.89%,and the simulation is basically the same as the actual one.The test results of turning radius show that the theoretical turning radius is 6.4m.In the actual test,due to different speed,the turning radius is within the range of 6.127m^6.5m,and the maximum error is 4.27%,which is within acceptable range.The design of the steering system meets the design requirements. |
