一、牵引特性与牵引计算铲土运输机械的牵引特性是铲土运输机械最重要的使用特性,一般以牵引特性曲线表示。牵引特性曲线由4～7条曲线组成,分别为:有效牵引功率曲线N_(KP)=N_(KP)(P_(KP));牵引效率曲线η_(KP)=η_(KP)(P_(KP));有效耗油率曲线g_(KP)=g_(KP)(P_(KP));滑转率曲线δ=δ(P_(KP));实际行驶速度曲线U=U(P_(KP));发动机净功率曲线N_(ez)=N_(ez)(P_(KP));净耗油量曲线G_(ez)=G_(ez)(P_(KP))。P_(KP)为有效牵引力。牵引特性曲线根据绘制方法的不同,可分
1. Traction Characteristics and Traction Calculation The traction characteristics of the shovel transportation machine are the most important use characteristics of the shovel transportation machine, and are generally represented by the traction characteristic curve. Traction characteristics curve consists of 4 to 7 curves, which are: effective traction power curve N_(KP)=N_(KP)(P_(KP)); traction efficiency curve η_(KP)=η_(KP)(P_(KP )); effective fuel consumption curve g_ (KP) = g_ (KP) (P_ (KP)); slip rate curve δ = δ (P_ (KP)); actual speed curve U = U (P_ (KP) ); engine net power curve N_ (ez) = N_ (ez) (P_ (KP)); net fuel consumption curve G_ (ez) = G_ (ez) (P_ (KP)). P_(KP) is effective traction. Traction characteristics can be divided according to different drawing methods
