AI Technical Summary

Technical Problem

Existing pressure burst testing machines cannot reproduce the combined load on automotive air intake pipes under actual working conditions, resulting in significant discrepancies between laboratory test results and actual vehicle usage results, and thus failing to effectively verify the reliability of the product.

Method used

A pressure burst test machine for automotive intake pipes was designed. Through a combined loading structure of piston cylinder and solenoid valve, the basic pulsating pressure and transient impact load are applied synchronously. A variable frequency hot and cold circulating fan is used to simulate a hot and cold alternating environment to achieve combined loading of multiple physical fields.

Benefits of technology

It accurately reproduces the load conditions of the automotive intake pipe under actual working conditions, improves the accuracy and reliability of the test results, and avoids the problem of pipe bursting in real vehicles when laboratory-qualified products are used.
