To study the influence of rotary inertia on gear flowmeter natural frequency, keep damping and leakage coefficient as constant.

结果表明：与增大泄漏系数、阻尼系数相比，减小转动惯量可以明显的提高流量计的频率响应。

Secondly, the relationship between rotary inertia coefficient, torsional stiffness, transmission gearbox and torsional vibration frequency is analyzed on the basis of the design model.

其次，在双质量飞轮设计模型的基础上，分析了双质量飞轮转动惯量系数、扭转刚度、变速器与系统扭振频率的关系。
