AI Technical Summary

Technical Problem

Existing vibration testing platforms cannot meet the requirements of high-frequency, low-amplitude, high-precision, and real-time closed-loop vibration characteristic testing for ultrasonic resonant tactile reproduction devices. They suffer from problems such as large measurement interference, poor ultrasonic frequency band adaptability, unadjustable excitation parameters, lagging data processing, low system integration, high energy consumption, and easy aging of components.

Method used

Employing a non-contact laser vibration measurement scheme and equipped with a programmable dual-parameter independently adjustable excitation system, it achieves fully automatic wideband frequency sweep and rapid resonant point identification from 25kHz to 40kHz, establishes an integrated real-time closed-loop test link, and builds a voltage segmented energy efficiency optimization model to meet the full-dimensional testing needs of ultrasonic tactile devices for micro-amplitude high-frequency vibration.

Benefits of technology

It achieves high-precision micro-amplitude vibration testing without additional interference, improves testing efficiency and system energy efficiency, extends device life, and is suitable for high-frequency vibration characteristic testing in the ultrasonic band.
