| Abstract: | In this paper, a method for analyzing the dynamic response of a structural system with variable mass, damping and stiffness is first presented. The dynamic equations of the structural system with variable mass annd stiffness are derived according to the whole working process of a grab unloader. In the end of the paper, an engineering example for analyzing the dynamic response of the whole working process of a bridge grab unloader and some conclusions are given. |
| Keywords: | dynamic response/ variable mass variable damping variable stiffness |
