摘要: 建立了永磁悬浮带式输送机悬浮支撑系统三维模型，对不同磁性输送带形状、永磁体布置形式、永磁体形状、偏载条件下永磁悬浮支撑系统稳定性进行了仿真。结果表明：槽型磁性输送带稳定性优于平型、V型磁性输送带，且承载能力表现最稳定；永磁体采用槽型结构时磁性输送带稳定性和承载能力较好；偏载会加剧磁性输送带的跑偏。为有效解决磁性输送带跑偏问题，设计了一种槽型磁性输送带防跑偏装置，通过在槽型磁性输送带两侧安装辅助辊轮，能进一步提高永磁悬浮带式输送机悬浮支撑系统的稳定性。Abstract: A 3D model of suspension support system of permanent magnetic suspension belt conveyor was established. Stability of permanent magnetic suspension support system under different magnetic conveyor belt shape, permanent magnet arrangement, permanent magnet shape and partial load condition were simulated. The results show that stability of groove-type magnetic conveyor belt is better than that of flat-type and V-type magnetic conveyor belts with stable bearing capacity. Stability and bearing capacity of conveyor belt are better when permanent magnet has groove-type structure. Partial load will increase deviation of magnetic conveyor belt. In order to effectively solve deviation problem of magnetic conveyor belt, an anti-deviation device for groove-type magnetic conveyor belt was designed. By installing auxiliary rollers on both sides of the groove-type magnetic conveyor belt, stability of the suspension support system of permanent magnetic suspension belt conveyor can be further improved.
