【Abstract】 The dynamic mechanical model is set up with three masses and two freedom mass spring system; A set of equations are developed to describe the vibration of the system, and the dynamic responses of the system are obtained through modular analysis. The formulas are given to calculate the coefficient of hoisting mechanism.更多还原
