摘　　要：加载试验台的可靠性是产品质量检验水平与能力的反映。新设计的功率1100 kW摇臂做加载试验时,试验台联接装置出现故障。通过拆解联接装置并分析产生的原因,提出改变润滑方式等改进措施,并重新进行试验验证,联接装置没有出现故障,温度合理。通过对联接装置的改进,大大提高了摇臂加载试验台的可靠性。The reliability of the loading test bench is a reflection of the product quality inspection level and capability.When the newly designed power 1100 kW ranging arm was used for the loading test,the connection device failed.Through the dismantling of the connection device and analysis of the reasons,the improvement measures such as the replacement of the lubrication method were proposed,and the test was verified again.The connection device has no fault and the temperature is reasonable.The reliability of the ranging arm loading test bench is greatly improved by the improvement of the connecting device.
