Abstract
The controllable gas vibrating system includes one exciting barrel, one piston, one guide bar, two baffle plates separately on two ends of the exciting barrel to form one sealed space together with the exciting barrel, ball valves, two motors and one control system to control the rotation of the motors. The piston is set on the guide bar for sliding relatively to the guide bar and inside the sealed space to separate the sealed space into one right gas chamber and one left gas chamber with ball valve controlled gas inlet and gas outlet each. The controllable gas vibrating system has controllable vibrating frequency, low cost and use convenience.
Description
Technical field
The present invention relates to a kind of controllable gas vibrating system that is used for earthquake simulation shaking table.
Background technology
The research of earthquake simulation shaking table has the history of decades, wherein the used excitation system of earthquake simulation shaking table has gas vibrating system, liquid excitation system, electromagnetic exciting system, though yet the strength that the gas exciting produces is big, but be difficult to control, and liquid exciting, electromagnetic exciting cost height, and electromagnetic exciting also is subjected to the restriction of current power.
