Tractor Chassis Optimization Design Based on Folding Technology

基于折叠技术的应用现状,系统分析了折叠技术的建模与分析方法。以拖拉机底盘为例,以提高自走式拖拉机底盘灵活性和可操作性为研究目标,使用折叠式框架和前平衡旋转轴,改进机械和工具在自行式底盘中心区的机械化挂接方式,构建一种当前轴以接近90°的角度转动时拖拉机围绕其中一个后轮原地转动的动态模型,以减少拖拉机悬挂农业机具转弯的阻力矩。研究结果表明:使用前旋转轴可以解决机具和工具在中心区的自动挂接问题,提高机动性,简化自走式拖拉机底盘的转向驱动,且在拖拉机田间运行过程中可以任意改变前轮轨道的理想转弯。田间运行颤振结果表明:使用旋转桥可以解决自动连接机具的问题,并确保桥的摆动,保持田间作业稳定性与可靠性。研究结果可为提升折叠技术在农业机械装备中的进一步应用提供技术参考与方案优化。

Based on the current application status of folding technology,this study systematically analyzes the modeling and sub-child method of folding technology,and takes the tractor chassis as the research target to improve the maneuverability of self-propelled tractor chassis,using the folding frame and front balanced rotating axle to improve the mechanized hook-up of machinery and tools in the center area of self-propelled chassis,and construct a kind of front axle rotating at an angle close to 90°when the The tractor is dynamically modeled to rotate in place around one of the rear wheels,and the use of a balanced front axle can greatly reduce the turning resistance moment.The results show that the use of the front swivel axle can solve the problem of automatic attachment of implements and tools in the central area,improve the mobility and simplify the steering drive of the self-propelled tractor chassis,and the ideal turn of the front wheel track can be changed arbitrarily during the tractor field operation.The field operation chatter results show that the use of the swivel axle can solve the problem of automatic attachment of implements and ensure the swing of the axle to maintain the field operation stability and reliability.The results of the study provide technical reference and optimization solutions for further application of upgrading folding technology in agricultural machinery and equipment.
