摘要
从弹性动力学入手，研究了摩擦式提升机在加速、减速和紧急制动时的弹性振动特性，给出了提升容器的加、减速度及动张力的计算公式，研究了采用梯形加速度曲线的动张力限制设计方法。
The paper studies on the elastic vibration characteristics of a friction hoist when hoist is accelerating, reducing and emergently braking, and gives a calculation formula for a hoisting vessel in its acceleration, reduction and active tension. The design method is researched in the paper for limiting active tension while adopting trapezoidal acceleration curve.
