AI Technical Summary

Technical Problem

Existing drop tests for automotive parts suffer from low efficiency, poor safety, and insufficient accuracy of test data, especially when testing the same site multiple times, site shifts are prone to occur.

Method used

The combination of a magnetic control module, a ball drop head assembly, and a positioning guide frame allows for precise release of the ball drop head assembly along the positioning guide frame. The ball drop head assembly then falls freely along the positioning guide frame and impacts the test piece, ensuring both safety and accuracy.

Benefits of technology

This technology enables the effective simulation of automotive parts impacted by ball heads at different energies, while ensuring safety and accuracy, thereby improving testing efficiency and data accuracy.
