摘要/Abstract

摘要： 为抑制矿井提升系统的纵向振动,设计了一种基于磁流变阻尼器的纵向振动减振悬挂装置。首先,建立了磁流变阻尼器力学模型,并对减振悬挂阻尼器进行了结构设计和磁路设计。其次,基于多物理场仿真软件COMSOL建立了磁流变阻尼器的多物理场耦合模型,在电磁场、流场的流-固耦合环境下分析了内部磁场、流场和压力分布状况,验证了机械结构和磁路分布设计的合理性。然后,通过耦合电磁场、流场和力场的动力学仿真,得到了磁流变阻尼器在正弦激励下的阻尼力F与位移x、频率f、振幅A、电流I和阻尼可调系数β之间的关系特性;仿真结果表明,在工作电流为0~1.4 A时,所设计阻尼器的最大阻尼力为4 993 N,最大阻尼可调系数为9.97。最后,试制样机验证了所设计的磁流变阻尼器可为减振悬挂装置提供所需的阻尼力,实现矿井提升系统纵向振动的抑制。

Abstract: In order to suppress the longitudinal vibration of the mine hoisting system,a longitudinal vibration-damping suspension device based on magnetorheological damper was designed. Firstly,a magnetorheological damper mechanical model was established,and the structural design and magnetic circuit design of the vibration-damping suspension damper were carried out; secondly,a multi-physical field coupling model of the magnetorheological damper was established based on the multi-physical field simulation software COMSOL,and the internal magnetic field,the flow field and the pressure distribution conditions were analyzed in the flow-solid coupling environment of the electromagnetic field and the flow field to validate the reasonableness of the design of the mechanical structure and the distribution of the magnetic circuit; and then,through the dynamic simulation of coupled electromagnetic field,flow field and force field,the relationship between the damping force F and displacement x,frequency f,amplitude A,current I and damping adjustable coefficient β under sinusoidal excitation of the magnetorheological damper was obtained; the simulation results show that,in the range of operating current from 0~1.4 A,the maximum damping force of the designed magnetorheological damper was 4 993 N,and the maximum damping adjustable coefficient was 9.97. Finally,the trial prototype verifies that the designed magnetorheological damper can provide the required damping force for the vibration-damping suspension device to achieve the suppression of longitudinal vibration of the mine hoisting system.
