AI Technical Summary

Technical Problem

Existing strength testing techniques for resin-bonded grinding wheels cannot simulate actual working conditions, especially coupled loading under high temperature, high speed, and dynamic lateral impact scenarios. This results in significant discrepancies between test results and actual safety performance, posing potential safety hazards.

Method used

A strength testing device for resin-bonded grinding wheels was designed, comprising a clamping and rotating assembly, an impact loading assembly, a temperature control assembly, and a PLC controller. It can simultaneously load high-speed centrifugal force field, temperature field, and lateral impact field under simulated actual working conditions. Through coordinated operation with the PLC controller, it can realize the reproduction of multiple scenarios and data acquisition.

Benefits of technology

It accurately reproduces the actual operating conditions of resin grinding wheels, provides real failure boundaries and safety performance data, reduces safety risks, and improves the relevance and accuracy of test results.
