The research of GS2 wire rope isolator maximum impact load
Various equipment always suffers impact damage widely when ships are subjected to the explosion.
The most efficient and convenient way to improve the ability of impact resistance for marine equipment is installing
shock absorber with good shock resistance between hull and equipment. However, the main mechanical equipment in China mainly takes common vibration isolators as
shock isolators and it focuses on vibration isolation function in usual when it is suffering impulse load, its impact energy will turn into potential energy with greater elasticity in a slower form.
At present, there is more extensive research about the vibration isolation performance parameters of the
anti vibration isolators while the research about impact performance is defective. Some data that is used for construction is always on the basis of its low dynamic behavior, so there is always big errors. Especially, the research about
wire rope isolators maximum impact load of marine is not enough, there is no systematic research basically in China.
At present, according to Ross vibration isolation element limit assessment standard, it adopts 15 times the amount of load or infinitesimal vibration isolators to stretch to 60 mm as element limit assessment standard. But this standard cannot reflect the performance of the isolation element impact roundly. For example, small deformation limit vibration isolation element with 15 times rated load means bad strong impact isolation effect, it may cause the damage to isolated equipment. 60 mm infinitesimal vibration isolators stretch under strong impact may have the tensile failure. Therefore, it is very important to judge the limit load of the vibration isolators reasonably.
