拖拉机──犁耕机组悬挂杆件的优化设计

Optimal Design of the Hitch Linkage for Tractor-plough

在基于改善拖拉机悬挂机构提升速比的基础上，建立了优化犁耕机组悬挂杆件的数学模型。计算结果表明优化方案较理想。

A mathematical model predicting the behaviour of a tractor-plough is pre-sented by optimizing the geometry of the three points hitch and improving the lift speed ra-tio,Calculated results show the optimal schenies are good.
