AI Technical Summary
Existing cross-fault tunnel simulation test equipment has problems such as excessive power device load, unsuitability for large-tonnage working conditions, excessively high power and structural strength requirements, and insufficient operational stability and safety, especially during large-tonnage vertical reciprocating motion, which is prone to impact and vibration.
The gravity balancing mechanism (including spring balancer and damping spring damper) is combined with the vertical displacement power mechanism. The gravity balancing mechanism shares the weight of the model box, so that the displacement simulation cylinder only needs to provide the driving force for vertical reciprocating motion. Combined with the sliding constant force clamping mechanism and reaction frame, the stable operation of the large-tonnage test system is achieved.
It significantly reduces the pressure on the hydraulic cylinder and its associated power source, lowers the drive power requirements and structural strength requirements, improves the operational stability and safety of the device, avoids problems such as insufficient drive power or structural fatigue, and extends the service life of the device.
