摘　　要：引入梯形中位线定理,以几何图形和胡克定律对各力之间关系,进行了清晰的阐述。提出了有效拉力释放系数Hα的概念,定义了常规因子K_(1),提供了一种最大有效拉力的计算方法,通过比例系数Xα证明了Hα的适用性和准确性。绘制了综合性能曲线图,探讨了紧边极限拉力F_(1)、松边极限拉力F_(2)、最大有效拉力F_(ec)、最大功率P_(0)等随带速v的变化规律。给出了最大应力与功率曲线图,阐明了最佳带速的选择方法、任意包角α0下最大功率P_(0)的计算方法,定义了安全系数S_(0)。By introducing the trapezoidal median line theorem,the relationship between forces is clearly expounded with geometric figures and Hooke’s law.The concept of effective tension release coefficient H_(α)is proposed,the conventional factor K_(1)is defined,and a calculation method of maximum effective tension is provided.The applicability and accuracy of Hαare proved by the proportional coefficient X_(α).The comprehensive performance curve is drawn.Under the change of belt-speed,the variation laws of tight edge limit tension F_(1),loose edge limit tension F_(2),maximum effective tension F_(ec)and maximum power P_(0)are discussed.The curve of maximum stress and power is given,the selection method of optimal belt-speed is clarified,the calculation method of maximum power P 0 under any envelope angleα_(0)is given,and the safety factor S_(0)is defined.
