    • The present invention provides a method of detecting shaft break in a shaft system comprising a shaft coupled between two masses. The method comprises a number of steps. Firstly, to define a time-dependent rotational speed equation for the shaft in terms of system inertia for an engine transient event. Then to discretize the rotational speed equation in terms of a discrete time constant in the discrete domain. Then to recursively define the discretized equation to give a recursive equation and to solve the recursive equation to determine the discrete time constant. Then to define a threshold as a function of engine power and then to set a shaft break signal to TRUE if the discrete time constant is greater than the threshold. A shaft break detection system is also provided by the present invention.
    • 本发明提供了一种检测轴系统中轴断裂的方法,该轴系统包括连接在两个质量块之间的轴。 该方法包括多个步骤。 首先,根据发动机瞬态事件的系统惯性来定义轴的时间相关旋转速度方程。 然后根据离散区域中的离散时间常数离散旋转速度方程。 然后递归地定义离散方程以给出递归方程并求解递归方程以确定离散时间常数。 然后,将阈值定义为发动机功率的函数,然后如果离散时间常数大于阈值,则将轴断裂信号设置为TRUE。 本发明还提供了一种轴断裂检测系统。
