AI Technical Summary

Technical Problem

Existing equipment test benches lack stability and safety under high impact and high vibration environments. Commonly used reinforced concrete foundations have poor vibration damping effects, affecting equipment operation and the safety of surrounding facilities.

Method used

The foundation structure of the impact vibration test bench includes the foundation body and vibration isolation device. It utilizes concrete foundation, vibration damping device and vibration isolation trench, combined with rubber shock absorbers, hydraulic dampers and other components to form a multi-layer vibration reduction system to reduce the impact of shock waves on surrounding equipment.

Benefits of technology

It improves the stable operation and safety of the equipment test bench under impact and vibration conditions, reduces disturbance to surrounding facilities, and extends the service life of the equipment.

Abstract

This application relates to the field of embedded part construction technology, and provides a foundation structure for an impact vibration resistant equipment test bench, including a foundation body and a vibration isolation device. The foundation body includes multiple foundation components that maintain a certain distance from each other and connecting components that connect the foundation components. The foundation components include a concrete foundation and a vibration damping device. The vibration damping device is connected to the equipment test bench. The vibration isolation device includes an inner wall, an outer wall, and a first vibration damping device. The inner wall surrounds the perimeter of the foundation body, and the inner wall and the outer wall maintain a distance to form a vibration isolation trench. The first vibration damping device is installed in the vibration isolation trench. By using the vibration isolation device to reduce the horizontal and vertical shock waves of the foundation pit, the disturbance to the surrounding equipment pit can be reduced, ensuring the stable operation and safety of the equipment test bench under impact vibration conditions, while also extending the service life of the equipment.
