摘　　要：起重机抗风防滑分析缺少整体研究,文中基于多体动力学,建立了风载荷作用下的起重机-轮边制动器模型,采用Hertz理论建立了轮-轨道、制动器-轮的接触力,对制动器制动过程中起重机的运行状态进行了分析。利用该模型可从整体上对起重机抗风防滑性能进行分析,并对起重机抗风防滑装置的研究具有重要意义。Considering lack of overall research on wind and skid resistance of crane, a crane-wheel side brake model under wind load is established based on multi-body dynamics in the paper, and Hertz theory is used to establish wheel-rail and brake-wheel contact force to analyze crane running during braking. With the model, wind and skid resistance of the crane can be analyzed as a whole, and the research is of great significance to study wind-resistant and anti-skid device of crane.
