AI Technical Summary

Technical Problem

Existing technologies are insufficient to effectively simulate and evaluate braking noise under low-temperature conditions, especially brake squeal, in the early stages of project development. This results in insufficient time to resolve the low-temperature noise problem, and bench testing cannot accurately simulate the actual vehicle usage conditions.

Method used

The low-temperature immersion chamber brake squeal evaluation method is adopted, including sample preparation, break-in, prototype preparation, low-temperature chamber setting and operation, and brake squeal evaluation. The braking squeal performance under user conditions is simulated through an inertia test bench and a low-temperature chamber, and objective data is collected.

Benefits of technology

It enables temperature-controlled low-temperature vehicle brake squeal testing in the early stages of project development, avoiding the impact of waiting for the cold season. It can quickly simulate the brake squeal performance after prolonged use by users, improving the accuracy and efficiency of the test.
