中低速磁浮列车悬浮系统模糊综合评价与改进设计
Fuzzy Comprehensive Evaluation and Improved Design of Levitation System for Medium and Low Speed Maglev Trains
摘要
Abstract
To enhance the fault tolerance capability of the levitation system of a medium and low speed maglev train,a reliability analysis was conducted using Failure Mode,Effects,and Criticality Analysis(FMECA),identifying typical failure modes.A fuzzy comprehensive evaluation based on expert judgment was employed to quantify the indicators,reducing subjective bias,and avoiding duplication of hazard values.The analytic hierarchy process(AHP)was used to assign weights to different influencing factors,ensuring that the calculated comprehensive hazard levels of failure modes better reflect practical engineering needs.Furthermore,based on Markov theory,improvement measures were proposed for failure modes with high comprehensive hazard levels.A prototype was developed,and levitation and fault simulation tests were conducted on a single levitation test bench.The results indicate that the control board,interface board,and power module exhibit the highest comprehensive hazard levels,which are 6.314 7,5.484 1,and 5.653 4,respectively.After a fault occurs,the master-slave switching time is less than 100 μs,with the levitation gap root-mean-square error remaining below 0.1 mm and acceleration fluctuations within 0.6 m/s2.关键词
