AI Technical Summary

Technical Problem

Existing experimental methods cannot accurately simulate the ice damage process of mechanical structures under underwater submerged jets and mechanical impacts, making it difficult to study crack propagation and ice damage mechanisms, and the repeatability and accuracy of the experiments are insufficient.

Method used

The test method combines high-speed submerged jet and mechanical impact. Through a data acquisition system and servo electric cylinder to control the impact head, combined with laser displacement sensor and high-speed camera, the impact load, deformation and crack evolution data are collected simultaneously to achieve precise control and non-contact measurement.

Benefits of technology

This study enabled in-depth analysis of crack propagation and ice damage mechanisms, ensuring the repeatability and accuracy of the experiments and providing high-precision ice damage test data support.
