APPARATUS FOR MEASURING AND ANALYZING THE VIBRATION OF A CAR HANDLE

摘要

An apparatus for measuring and analyzing vibration of a steering wheel of a vehicle, comprising: a vibration detector comprising one accelerometer disposed at the left and right sides of the steering wheel in the same direction and an accelerometer disposed at opposite sides of the steering wheel; and a vibration signal for amplifying the vibration signal detected by the vibration detector. It is attached to an amplifier, a vibration signal separation detecting unit for separating the vibration signal amplified by the vibration signal amplifier into a digital signal by detecting the shimmy, shake and total vibration signal, and a slip ring installed to be rotatable with the axles of the front wheels. Vibration measurement of the steering wheel of the vehicle comprising a phase detector configured to attach an optical sensor and a rotary encoder to the adapter, and a detection signal processor formed of a computer, a monitor, and a peripheral device to process and display the separated detected vibration signal and the detected phase. And an analysis device.
