Anti-impact device for switching equipment connecting modes

Abstract

The invention discloses an anti-impact device for switching equipment connecting modes. The anti-impact device comprises an elastic vibration isolator arranged between a hull foundation and marine power equipment, an acceleration sensor is arranged on the hull foundation and connected with a DSP controller, and the elastic vibration isolator is connected with the marine power equipment through a cylinder. The cylinder comprises a cylinder body, a piston and a piston rod, the piston rod stretches out of the upper end of the cylinder body and is fixedly connected with the marine power equipment, the lower end of the cylinder body is fixedly connected with the elastic vibration isolator, an air inflation hole and an exhaust hole are formed in the side wall of the lower portion of the cylinder body, and the exhaust hole is controlled to be opened and closed by a solenoid valve connected with the DSP controller. Whether a system is in a vibrating state or in an impacting state can be judged automatically, the anti-impact device has good impact resistance and vibration isolation performance, the impact acceleration amplitude of the equipment under the action of impact is effectively reduced, under the action of impact loads, relative displacement between the hull foundation and the isolated equipment can be reduced, response speed of the system is high, and the anti-impact device can resist to impact timely.

Description

technical field [0001] The invention relates to the field of anti-shock of ship equipment, in particular to an anti-shock device for switching equipment connection modes. Background technique [0002] Ships and ship equipment will inevitably face impact problems during their service, and the strength of the impact safety of ship equipment will directly affect the combat effectiveness and vitality of ships in war. With the development of modern military technology, the impact equivalent and impact duration of weapon explosions have increased significantly, and the threat to marine power equipment has become more serious. Even in peacetime, the collision impact caused by cruising may cause great harm to ships, especially to marine power equipment. In this context, improving the impact isolation performance of marine power equipment has become an urgent need to ensure the vitality of modern ships. [0003] The traditional design method is to carry out the vibration isolation ...

Problems solved by technology

However, due to structural constraints in the design, the vibration isolation performance of the vibration isolator is ideal, but the impact resistance performance often cannot meet the actual requirements.

At present, in order to improve the shock resistance of the vibration isolation system, the method of installing a limiter in the vibration isolation system is generally used in actual engineering, but at the same time a new problem is introduced: if the marine power equipment hits the limit when it is impacted A secondary impact will occur when the device is used, making the impact process a complex nonlinear problem, increasing the difficulty of research

[0004] In response to the above problems, there is no ideal anti-shock component in my country at present; it can satisfy both the absolute acceleration amplitude of the marine power equipment (absolute acceleration amplitude for short) and the relative displacement amplitude between the marine power equipment and the hull foundation ( Abbreviated as relative displacement amplitude) the anti-shock device is still in the blank stage
