查询词典 systems engineering

The generalized reliability of single failure mode component and unit structure under different kinds of uncertainty factors is treated perspicuously and classified. Combined with the three class fortify standard of aseismic design code,the conception of reliability vector of structures and systems with intermediate state before failure is put forward, and the calculation model of reliability vector with three stage working modes of "safety-intermediate-failure" and the operation rules of reliability vector of the simple aseismic engineering systems composed by structures are established.

The larger subharmonic component will be introduced into the system after the instability of system periodic motions, the motion of systems will be nonsynchronous precession and the amplitude of alternate stress in the rotor shaft is high. The long-term existence of instability will directly threaten the safe running of the rotor systems. Research on the influence of the change of system parameters on the system dynamical behaviors, the stability of system periodic solutions with the change of system rotational speed and the system motion after instability will have the theoretical and engineering-oriented significance for the long-term safe running of large-scale rotating machinery.

转子系统失稳后会产生较大的低频振动分量，系统运动出现非协调进动，系统转轴中会产生幅值很大的交变应力，转子失稳状态的存在直接影响系统的安全运行，因此研究转子系统自身参数的变化对系统动力稳定性的影响，研究系统周期解随工作转速的变化情况及其失稳后的运动规律，对大型旋转机械的安全稳定运行具有重要的理论意义和工程实用价值。
