摘　　要：针对起重机在风载荷作用下的刹车制动过程,提出了一种动力子结构分析方法,该方法将实现以车轮组子结构代替整机结构进行制动仿真分析,并以简单子结构的测试结果反映整体结构的测试性能,完成对整体结构制动性能的评价。该研究基于Adams虚拟仿真平台上,对整机与子结构在风载荷作用下的制动过程分别进行动力学仿真,并在保证相同制动效果的前提下,得到制动过程中整机风载荷与子结构等效风载荷的相关联系,进而确保子结构可替代整机在风载荷下制动仿真的可行性。The paper proposes a dynamic substructure analysis method to study braking process of crane under wind load. With the method, wheel group substructure can replace the whole structure in braking simulation analysis, and test results of simple substructure can reflect test performance of the whole structure to evaluate the structure＇ s braking performance. Based on Adams virtual simulation platform, both the whole structure and substructure are subject to dynamic simulation of braking process under wind load, and the correlation between wind load of the whole structure and equivalent wind load of substructure during braking is obtained under the premise of the same braking effect to further ensure that replacing the whole structure with substructure for braking simulation under wind load is feasible.
