摘要
制动器的设计与选型是桥式起重机生产过程的重要环节,制动器的位置与布局关系起重机的运行平稳与安全。以10 t桥式起重机为设计对象,对起升机构进行动力学分析,建立了数学模型,计算了数学模型所需的转动惯量;并对制动器不同布置方案进行了计算与仿真,利用Matlab软件得到了制动器制动的最大力矩,分析得出了制动器设计的最优方案。
The design and selection of the brake is an important part during the process of bridge crane manufac- turing, the position and layout of brake are related to the stable operation and crane safety. In this paper, the ba- sic design parameter is weight of 10 tons bridge crane, the lifting mechanism for dynamic analysis and the mathe- matical modelsare established andthe rotational inertia of the mathematical model are evaluated. Different layout schemes of the brake are calculated and simulated, the maximum torque brakeis obtained by using Matlab soft- ware, and the optimal scheme of the brake design has been analyzed.
