Abstract

The invention discloses a double-hydraulic-motor drive type large-displacement earthquake shaking simulation device and method. The device comprises a shake table body and a shake controller. The shake table body comprises a first horizontal guide rail, a first coupler, a first hydraulic motor, a first electro-hydraulic servo valve, a second horizontal guide rail, a second hydraulic motor, a second electro-hydraulic servo valve, a second coupler, a third horizontal guide rail, a base, a motion table top, a first ball screw, a first bearing block, a second ball screw, a second bearing block, an acceleration sensor and a displacement sensor. According to the device and method, a combined drive type structure of hydraulic motors and ball screws is adopted, and therefore low-frequency response and large-displacement motion control characters of earthquake simulation tests can be achieved; meanwhile, the earthquake shaking simulation device can have larger anti-overturning torque by adopting the horizontal guide rail structure, and therefore stability and reliability of the shake device in the working process can be guaranteed.

Description

technical field [0001] The invention relates to an earthquake simulation vibration device, in particular to a double hydraulic motor driven earthquake simulation vibration device and method. Background technique [0002] Earthquake simulation vibration devices are widely used in road simulation, building structure anti-seismic, civil engineering and other fields. In building structure anti-seismic experiments, it is often necessary to simulate real earthquake waveforms. During the earthquake process of high-rise building structures, their horizontal displacement range is very large, up to several meters , conventional seismic simulation vibration devices often use hydraulic cylinders to drive the vibration device, the movement range of the vibration device is limited by the length of the piston rod of the cylinder, it is difficult to achieve large displacement movement, which further limits the low-frequency characteristics of the earthquake simulation vibration device, there...
