陀螺效应对发动机悬置系统TRA解耦的影响(英文)

Influence of Gyro Effect on Torque Roll Axis Decoupling of an Engine Mounting System

对扭矩轴(TRA)解耦方法进行了解释,并在理论上讨论、分析了发动机内旋转件的陀螺效应对TRA解耦的影响。通过算例研究了在比例、非比例两种阻尼情况下陀螺效应对TRA解耦的不同影响特性。结果表明,对于比例阻尼系统和一般的非比例阻尼系统而言,陀螺效应使得系统从TRA解耦变为耦合,而对于一类特殊的非比例阻尼系统陀螺效应对TRA解耦无影响。

The torque roll axis （TRA） decoupling method is described and the influence of gyro effect on the TRA decoupling method is also discussed and analyzed theoretically. The results show that the TRA decoupling may be influenced by gyro effect： gyro effect makes the proportional and the general nonproportional damping system change from TRA decoupling to coupling, but in special non-proportional damping case, gyro effect have no any effect on the TRA decoupling.
