Detection for Operation Response Vibration Mode of Vans Back Door at Exciting with Fixed-frequency

摘要：

　　A type of PSV-400-B scanning laser vibrometer is used to obtain the operation response vibration mode(ORVM)of vans back door at exciting environment of fixed-frequency.According to the ORVM,the locations with largest deformation and second-largest deformation are found at vans back door.The difference between modal vibration mode and operation response vibration mode is analyzed.The vibration test principal about Laser-Doppler is offered.The detection scheme based on Laser-Doppler principle is established for ORVM of vans back door.The ORVM of vans back door is obtained and analyzed at the four frequency dots from base-frequency to third frequency.The result shows that the measurement to get ORVM of vans back door is with feasibility introduced in the paper.
