Abstract: |
Objective To solve the poor precision and low simulation degree of traditional test and verify the reliability of smart meter in random vibration. Methods In this paper, the equivalent random vibration test method based on fatigue damage spectrum was applied to the smart meter road transportation vibration test. Firstly, the concept of fatigue load spectrum and its acquisition method were proposed. The collected vibration data was processed to obtain the power spectral density used to accelerate the vibration test. Finally, the feasibility and advantages of applying the random vibration test method based on fatigue damage spectrum in simulation of road transport with smart meter were verified.. Results The cumulative fatigue damage error before and after the test is accelerated with this method was 6.4%. Conclusion This method can not only greatly reduce the test time, but also save a lot of manpower and material resources. |
