DYNAMIC TENSION CALCULATION AND DYNAMIC DESIGN OF STEEL ROPE OF MULTI-ROPE FRICTION HOIST

摘要

This paper gives viscoelastic oscillatory equation, displacement properties and dynamic tension calculation method of steel rope of multi-rope friction hoist; studies no-skid safety design method, controlled start and controlled stop design method; provides design theory and calculation method of limiting and eliminating steel rope' elastic vibration during the normal start and emergency stop. An example of emergency stop is presented for the calculation and comparision with experimental calculation results from England, and the difference is only 2%.
