摘要
从牛顿—欧拉方程出发建立了舰船机电设备抗冲隔振系统的非线性模型,并通过实例计算结果指出,该类隔振器具有良好的隔振效果。研究表明,由于转动角速度较小,在运动方程中的陀螺力项可以忽略,这对于隔振系统建模有重要意义。该结论对如何正确设计设备支撑保护系统提供了理论参考依据。
In this paper,a nonlinear model on anti-shock iso la tion system for marine equipment has been derived from Newton-Euler's equation .And the calculating results of a case-study have indicated that the isolator is of sound effectiveness on vibration isolation.It shows that in motion equat ions all gyroscopic items could be neglected because the rotational velocity is rather small.It is of important significance for model building of a isolatio n system.In conclusion,the theoretical basis is presented on how to correctly design equipment protection system.
