Vulcanize Rubber Ship Launching Airbags Customized Size High Strength
Vulcanize Rubber AirBag Dia and Length Customize Ship Lifting Marine Air bag
Ship lifting marine airbag is a high-strength plain surface airbag, which is widely used in moving large objects and marine salvage. It's made of outer rubber layer, synthetic-tyre-cord layers, inner rubber layer and metal end parts. The inner rubber layer is made separately and inflated during the whole production, therefore the air tightness is guaranteed.
Performance Calculation Principle of Airbags
The bearing capacity of marine rubber air bags was calculated based on the working pressure, contact area. Herein, working pressure was got upon the burst pressure and safety working factor.
Because of the flexibility of rubebr airbag the contact area will be affected by some terms which include the carried ship condition, the different position from gravity center during the process of ship launching and pulling. So the bearing capacity of air bags will vary as well as the contact area.
The approximate bearing capacity can be calculated as follows:
F=PS
S=π x (D1-D2)/2
Mark:
F: Bearing capacity
P: Inner pressure
S: Contact area
D1: Diameter of airbags when free of loat
D2: Working height of airbags when loaded
