Base chassis design of air compressor in warship

针对舰船用空气压缩机振动、噪声和安全性问题,对舰船用空气压缩机公共底架的设计进行了研究,利用现代计算工具对一型公共底架的结构设计进行了不同的舰船环境下静力学、动力学和模态计算,研究分析了舰船在倾斜、摇摆环境条件下公共底架的应力、应变的变化,强调公共底架的设计在满足强度要求的同时应具有足够的刚度,通过开孔、加筋在满足机组结构强度的基础上、调整公共底架的模态可以有效地减小机组的振动和噪声,提出了按静G法校核在冲击环境下公共底架的承受能力可行性,安装孔和安装螺栓的设计选型将直接影响到机组的抗冲击能力。研究结果表明,该方法能够使舰船空气压缩机噪声进一步降低和提高舰船用空气压缩机抗冲击安全性、其他类似的压缩机设计时可以参考。

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.
