摘　　要：为了确定深井提升机制动系统的振动特性,避免其在使用过程中发生共振现象,文章以TP1-150型矿井提升机制动器系统为研究对象,通过Solid Works软件建立制动器系统的的三维模型,利用ANSYS Workbench软件建立该制动系统的有限元模型,对制动器及制动系统进行模态分析,得到前10阶固有频率和主振型。为确保提升机制动系统结构能经受住不同频率下的各种正弦载荷,通过谐响应分析得到系统的振幅-频率曲线,并确定了该制动系统的危险频率范围和系统发生共振时可能产生的最大振动幅值。The hoist braking system is a key part of mine hoist and an important barrier to ensure the safe operation of hoists. In order to determine the vibration characteristics of the deep shaft hoist braking system and avoid the resonance phenomenon in the operation, we took the TP1-150 type mine hoisting mechanism system as the research object,established the 3 D model of the brake system through the Solid Works, and the finite element model using ANSYS Workbench. The first ten natural frequencies and the main vibration modes are obtained from the modal analysis. In addition,to ensure the hoist braking system configuration can withstand various sinusoidal loads at different frequencies,the amplitude frequency curve is obtained by the harmonic response analysis,which determines the range of dangerous frequency and the maximum vibration amplitude of the of the braking system when the system resonance occurs.
