[Application Example] Noise Inspection for Electric Assist Bicycle Drive Unit

With the use of the abnormal sound inspection device, it is possible to quantitatively detect products that emit sounds different from normal ones!

Our "Abnormal Noise Inspection Device" utilizes an inspection algorithm based on the Maharano Vista Guchi method to automatically and quantitatively inspect the quality of sounds and vibrations. We would like to introduce a case where the "Abnormal Noise Inspection Device" was applied to the abnormal noise inspection of drive units for electric assist bicycles. Traditionally, after assembly, operators would listen to the sounds to make judgments, but by using this device, we can quantitatively detect products that emit sounds different from normal ones. 【Case Study】 ■ Issues - The occurrence of abnormal noises during use in electric assist bicycles significantly impacts product value and can lead to complaints. - Traditionally, operators would listen to sounds to make judgments after assembly. ■ Application Results - By using the abnormal noise inspection device, we can quantitatively detect products that emit sounds different from normal ones. *For more details, please refer to the PDF document or feel free to contact us.
