A new shock factor of SWATH catamaran subjected to underwater explosion
چکیده انگلیسی
In order to measure the extreme degree of the impact environment on a SWATH (small waterplane area twin hull) catamaran subjected to an underwater explosion, this work defines a new type of shock factor based on shock wave energy. This new shock factor is used as a parameter to describe the response from this kind of ship, and it is divided into two categories according to characteristics of the SWATH catamaran structure. This research used finite element software to simulate and calculate the response of SWATH catamaran subjected to an underwater explosion. The validity of this new shock factor is proved in three categories, including total kinetic energy, total strain energy and shock spectrum. The results show that the responses of the SWATH catamaran structure are similar when the new shock factor is equal, and it is also appropriate for situations involving short explosive distances.
