摘要
针对减少农田土壤机械压实的技术措施,在常规轮式行走机构的基础上,提出配备超低气压轮胎的农用全地形仿形行走底盘的解决方案。建立了超低气压轮胎的地面力学模型,研究了配备超低气压轮胎的农用全地形仿形行走底盘的地面力学特性,并与现有的四轮驱动拖拉机进行对比分析,结果表明,农用全地形仿形行走车能够有效减小土壤机械压实,且牵引性能良好,满足现代农业的发展需要。
According to the technical measures for reducing the mechanical soil compaction,all terrain adaptive locomotion chassis for farmland with ultra-low pressure tires was proposed as solution scheme based on the conventional wheeled locomotion mechanism.The mechanical model between the tire and ultra-low pressure was established.The terramechanics of all terrain adaptive locomotion chassis for farmland which used ultra-low pressure tires was anayled.At last,compared with the existing four-wheel drive tractor,it was proved that all terrain adaptive locomotion vehicles for farmland could reduce the mechanical soil compaction and met the modern agriculture's need with well performance and tractive effort.
