| Abstract: | By the theoretical deduction,the expression of displacement response from boom of a gantry crane excitated under the process of a cargo lifting off ground has been established.The relationship between vibration of the boom and sustaining time of the excitation is discussed deeply.For the lifting dynamic characteristics of the boom has been carried out,the theoretical foundation for the vibration controlling and determination of the dynamic load coefficient can be provided. |
