摘　　要：本文以桥门式起重机起升机构的能耗分析为研究对象,依据键合图理论建立了一种适用性广泛的键合图模型。归纳出相关零部件建模所需的键合图元,不同型号起重机机构进行参数替换后直接进行分析。同时本文还提出了一种对各阻性元件阻尼参数进行估算的方法,并经仿真实验证实了该方法的有效性。提出了桥门式起重机各零部件能效对整体能效的影响因数计算公式,得到起升机构各零部件对整体能效具体影响因数。The hoisting mechanism of bridge and gantry crane is taken as the research target in this paper. According to the bond graph theory, a bond graph model with wide applicability was established for researching the energy consumption in the hoisting mechanism. In this paper, the bonding primitives for modeling of various components were summarized, which can make different types of cranes directly simulate after parameter replacement. At the same time, this paper also proposes a method to estimate the damping parameters of each resistive element, and the simulation results show that the method is effective. Finally, the paper puts forward the calculation formula of the influence factor of the energy efficiency of each part of the bridge and gantry crane on the overall energy efficiency, and obtains the specific influence factors of the components of the hoisting mechanism on the overall energy efficiency.
