Abstract:

To address the dynamic behavior of luffing jib tower crane under unloading impact conditions， a virtual prototype modeling method of a crane based on a non-parametric model and a crane anti-backward-tilting test method are proposed. Firstly， through the characteristic test of the hydraulic anti-backward-tilting device （HATD） and the unloading test of the unloader， a non-parametric model describing the damping characteristics of the HATD and the excitation function of the unloading load are established respectively. Then， the rigid-flexible coupling model of the tower crane and the non-parametric model established through the unit test are integrated into the virtual prototype model of the crane， and the virtual prototype simulations under a series of unloading conditions are carried out. The remote operation method is used to implement the anti-backward-tilting test of a luffing jib tower crane， and the validity of the simulation model is verified through a series of load tests. Finally， the dynamic response of the crane structure under extreme unloading conditions is predicted through simulation， which provides a quantitative basis for the design of the key structure of the crane.
