Abstract

This paper focuses on the special working condition-accidental loss of the effective load of sub-boom working conditions for combined lattice boom, establishes a rigid-flexible coupled model of the sub-boom system based on ANSYS and ADAMS, and applies multi-body dynamics analysis method to conduct theoretical modeling and numerical simulation of unexpected loss of effective load under the two limit working conditions-minimum radius but maximum capacity and maximum lifting moment. Also, the paper studies dynamic response of the structure under the action of vibration and impact excitations, and explores the influence rule of the dynamic performance of the sub-boom system when the effective load loses unexpectedly under different unloading time, lifting ratio and lifting acceleration time. The result of the research indicates that reasonably prolonging the unloading time and lifting acceleration time can contribute to improving the dynamic behavior and service life of the structure as well as properly increasing the lifting ratio.
