【摘要】：为了保证低阻力永磁带式输送机的正常稳定运行,对随机载荷作用下输送机悬浮支撑装置的自适应特性进行仿真研究。在合理假设的基础上建立了悬浮支撑装置的纵向随机振动模型;经过三维实体造型,自适应控制系统建模,外部随机载荷的定义及边界条件的施加等环节,完成跨平台多软件联合仿真环境下的悬浮支撑装置虚拟样机,并进行仿真模拟。仿真结果表明,在随机载荷的作用下,输送带运行状态失稳;随着输送带悬浮气隙的变化,磁悬浮力进一步调整,从而能再次达到系统平衡,与试验结果相符。永磁悬浮带式输送机悬浮支撑装置具有自适应动态调整功能。
[Abstract]:In order to ensure the normal and stable operation of low resistance permanent magnet belt conveyor. The adaptive characteristics of suspension support device of conveyer under random load are simulated. The longitudinal random vibration model of suspension support device is established on the basis of reasonable assumptions. After 3D solid modeling, adaptive control system modeling, the definition of external random load and the application of boundary conditions, the virtual prototype of suspension support device under multi-platform and multi-software joint simulation environment is completed. The simulation results show that, under the action of random load, the running state of conveyor belt is unstable. With the change of the suspension air gap of the conveyor belt, the magnetic suspended buoyancy is further adjusted, so that the balance of the system can be achieved again, which is consistent with the test results. The suspension support device of the permanent magnetic suspension belt conveyor has the function of adaptive dynamic adjustment.

【正文快照】： 带式输送机作为世界上重要的散状物料连续输送设备之一,应用范围相当广泛[1]。普通带式输送机依靠托辊支撑输送带和物料,当整机较长时,其主要阻力主要由数量众多的托辊产生,能源耗费巨大[2]。永磁悬浮带式输送机是最近发展的一种新型低阻力带式输送机,它改变了传统的输送带支
