摘　　要：空气压缩机广泛应用于人们的生活与工作中,其振动与噪声日益受到重视.文章以某型船用空气压缩机为研究对象,对其进行平衡机构设计及振动优化研究.在平衡轴的设计中,根据导致机体产生振动的不平衡激励力的计算公式,反推计算所需平衡力的大小,进行平衡轴参数设计计算,然后对曲柄连杆机构进行动力学仿真,旨在运用仿真的方法验证加装平衡机构的正确性和可行性.最后进行整机的瞬态响应分析.结果表明,平衡机构对整机减振效果明显.In this paper,a marine air compressor is taken as the research object,and its balance mechanism design and vibration optimization were studied.In the design of balance shaft,according to the calculation formula of unbalanced excitation force that causes the body to vibrate,the required balance force was back-calculated and then the balance shaft parameters were designed and calculated.Through the dynamic simulation of crank-link mechanism,the correctness and feasibility of adding balancing mechanism were verified Finally,the transient response of the whole machine was analyzed.The results show that the balancing mechanism has obvious damping effect on the whole machine.
