Title:
AUTOMOTIVE BODY VIBRATION CHARACTERISTIC TESTING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/038714
Kind Code:
A1
Abstract:
In an automotive body vibration characteristic testing method according to the present invention, vibration is input into an automotive body 100 and vibration characteristics of the automotive body are found. Said testing method includes an excitation step S1 for exciting the automotive body 100 by setting a plurality of vibration input locations 111 on the automotive body 100, which is supported by an air cushion 211, and inputting vibration into each of the plurality of vibration input locations 111 which have been set, and a vibration measurement step S3 for measuring data regarding the vibration characteristics of the automotive body 100 which has been excited. In the excitation step S1, vibration input waves input into some of the vibration input locations 111 on the automotive body 100 are more delayed than vibration input waves input into other vibration input locations 111.
