目前,振动测量技术在航空工业科研生产领域中的应用越来越广,无论在生产现场或试验室,均已配备了许多振动测试设备。因此,振动传感器的常规校准工作量逐渐增加。以前沿用的绝对校准法,由于设备投资大、技术要求高、校正时间长,显然已不能满足工程上常规校准的要求而为比较校准法所代替。 At present, the vibration measurement technology in the field of aviation industry research and application of more and more widely, both in the production site or laboratory, have been equipped with a number of vibration test equipment. Therefore, the conventional calibration workload of the vibration sensor gradually increases. The absolute calibration method used in the past was replaced by the comparative calibration method due to the large equipment investment, high technical requirements and long correction time, which obviously can not meet the requirements of conventional calibration in engineering.
