AI Technical Summary

Technical Problem

Existing tire dynamic balancing testing technology cannot effectively suppress low-frequency, high-energy impact vibration interference from nearby equipment during online testing, leading to measurement data drift. Furthermore, manual operation cannot be matched with automated equipment, affecting production cycle time and measurement accuracy.

Method used

By employing features such as automatic loading of permanent calibration parameters, phase-locked loop tracking and narrowband filtering, automatic marking, and directional presentation, a closed-loop detection link is constructed to track the spindle speed in real time, suppress interference, achieve high-precision phase calculation, and achieve seamless connection of double-sided operation through automatic flipping and directional presentation.

Benefits of technology

It improves the anti-interference capability, counterweight accuracy, and production cycle of online detection, enhances human-machine collaboration efficiency, and constructs a closed-loop quality traceability system from measurement to counterweight, ensuring a high-precision and efficient detection process.

Abstract

This invention relates to the field of vehicle testing technology, specifically to an online tire dynamic balancing testing method and system. It includes a parameter data loading unit, a signal acquisition unit, a phase angle calculation unit, an installation angle adjustment unit, and a flipping execution unit. This invention effectively solves the contradiction between measurement accuracy and efficiency in multi-specification line changes under strong interference environments in industrial settings by deeply coupling features such as automatic loading of permanent calibration parameters, narrowband filtering based on phase-locked loop tracking, automatic marking, directional presentation, and automatic flipping into a closed-loop testing link. Specifically, the narrowband filter center frequency tracks the spindle speed in real time, significantly suppressing low-frequency impact interference from nearby equipment and ensuring high-precision phase calculation; permanent calibration parameters are automatically recalled according to model after one calibration, reducing changeover time to milliseconds; automatic marking and directional rotation work together to eliminate the time-consuming manual positioning; and automatic flipping and reverse directional presentation achieve seamless integration of double-sided operations.
