Abstract

The invention discloses a method for quickly evaluating the sound insulation performance of a ship bulkhead structure. The method comprises the following steps: step 1, establishing a sound insulationperformance simulation test model; step 2, setting physical parameters of the bulkhead to be measured; and step 3, calculating the weighted sound insulation index of the bulkhead to be measured. According to the invention, a laboratory detection environment for cabin structure noise testing can be simulated. The sound insulation performance of the ship bulkhead structure is subjected to analoguesimulation to acquire the sound insulation performance index of the bulkhead structure. The method can be used for calculating the sound insulation indexes of the ship cabin combined wallboard and thecombined deck. Due to the fact that a bulkhead structure of any combination can be simulated, the defect that a manufacturer test report result is incomplete is overcome. Designers can find a sound insulation structure combination with the optimal cost performance. Design and manufacturing cost is reduced, and great significance is achieved for ship sound insulation calculation and bulkhead structure design.
