船舶压缩机往复惯性力计算分析与改进研究
Study on Reciprocating Inertia Force Calculation Analysis and Improvement of Marine Compressor

文章采用欧拉公式研究压缩机的振动、噪声问题并改进其计算结果。利用复变函数论推导出W型机器运转时一、二阶惯性力公式与图像、相位与幅值，从理论上揭示夹角γ、往复质量m对其合力的影响。针对具体的型式采用合适的平衡机构诸如行星齿轮机构来平衡一、二阶惯性力。分析结果表明，三列往复运动的机械结构(质量大小、夹角、转速、曲柄连杆比等)决定了其惯性力模式，而与转向无关。
In this paper, Euler formula is used to study the vibration and noise of compressors and improve its calculation results. The first- and second-order inertia force formulae and images, phases and amplitudes of W-type machines are derived by using complex variable function theory. The influence of angle γ and reciprocating mass m on resultant force is theoretically revealed. An appropriate balancing mechanism, such as planetary gear mechanism, is used to balance the first- and second-order inertial forces according to specific types. The analysis results show that the mechanical structure of the three-column reciprocating machinery (mass size, angle, speed, crank link ratio, etc.) determines its inertial force pattern, which is independent of the steering.
