based on fans fault system analysis, imbalance and unalignment two fault is carried out on gb4-73no . 8d test-bed . vibration test is carried out on vary rotate speed diffuser coupling and throttle . data file is analyzed by matlab function, then effect of imbalance and unalignment according to vary factor is found 根据对通风机故障的系统分析,决定在gb4-73no.8d通风机试验台上进行不平衡和不对中两种故障,在不同转速、不同导流器开度和不同节流锥阻力的各种工况下进行振动试验,用编写的matlab程序对数据文件进行分析,得到不同因素对不平衡和不对中故障的影响。
