Abstract: Aiming at the problem of ships with air compressor vibration and noise and security issues, the design of the chassis was studied. Statics, dynamics and modal calculation were analyzed using modern computing tools to different type of structure design of the chassis of the marine environment, the ship under the condition of tilt, swing environmental public chassis of the change of the stress, strain, focuses on the design of the chassis and the request of structure strength should have enough stiffness. The chassis modal was adjusted through opening and reinforcement in the unit on the basis of structural strength to effectively reduce the vibration and noise of the units. Static G method was proposed as the check in the shock environment public chassis of feasibility of the design of the mounting holes and installing bolts, which will affect the impact resistant ability of the unit. The research results show that this method can make the ship air compressor noise reduction and further increasing the safety of the ship impact resistant with air compressor and other similar compressor design can refer to.
