中文摘要：

传统的三点悬挂方式过于依赖生产经验,不能适应现代农业机具设计和开发的快速发展,为更好地保证犁耕的作业质量,必须在悬挂方式上进行合理的调整。本文对悬挂犁与拖拉机挂接的方式进行了重新设计,使悬挂犁和拖拉机三点悬挂构成挂接机组,犁的挂接点落在拖拉机的动力中心和犁的阻力中心的连线上,即三点构成一条直线,而将挂接机组上的牵引点做为虚牵引点。同时,结合南疆土壤特性,并利用Mat Lab软件优化了相关参数,最终各性能参数与悬挂犁标准参数更接近,充分证明了悬挂方式改进的合理性。

英文摘要：

The traditional three-point suspension way too dependent on experience, can not adapt to the rapid development of modern agriculture machinery design and development, in order to better ensure the quality of work of plowing, you must make reasonable adjustments in the suspension mode. The article on the suspension and tractor plow articulated manner has been redesigned to make the plow and tractor three-point suspension constituted suspension mount unit, plow mount point falls tractor and plow power center of resistance center connection, that is, three points form a straight line, but will mount tow point on the unit as a virtual traction point, combined with soil properties in southern Xinjiang , and the use of software to optimize the parameters, performance parameters and each final suspension plow closer to the stand- ard parameters, demonstrating ways to improve the susoension of rationality.
