  1. By the result of these experiments, acoustic emission ( ae ) was chosen to use in the research. at the same time, we analyse the phenomenon of acoustic emission at the base of theory, the characteristic signal of acoustic emission which comes from the faulty bearing at the angle of application, and the expression of the characteristic signal. contrast was also made on the data achieved separately from vibrational signal and ae signal, and it is proved that ae is feasible and available to the diagnosis to the fault of the rolling bearing

    主要工作有如下幾方面:對本段前期實驗室階段採用的振動幅值域處理進行了分析,並研製了現場所使用的滾動軸承故障檢測裝置,將參數診斷應用於段修現場,且做了大試驗;對于現場試驗中所出現的問題進行了分析,提出將聲發射的方用於軸承的在線故障診斷;從理論上分析了聲發射現象,從應用的角度分析故障軸承的聲發射信號的特徵以及聲發射信號特徵的,並在實驗室中,採用振動和聲發射實時檢測的實驗數據進行了對比和分析,證明了使用聲發射對軸承故障檢測的可行性和有效性。
  2. The problem is then fed to a nonlinear programming routine to solve for all parameters. the flight dynamics model with yawing motion of uh - 60a is given, scale factors of state variables and control variables are applied based on the consideration of algorithm convergence. then, the optimization of trajectories is expressed as optimal control problem with a performance index constrained by helicopter performance limits, faa regulation and so on

    首先,建立帶偏航運動的直升機點質模型,然後對狀態變和控制變進行處理,因為狀態變和控制變值相差較大,這使得優化演算收斂效果變差,所以需要選擇適當的縮放因子,最後把直升機單臺發動機停車后的飛行軌跡成一個最優控制問題,即在考慮直升機性能限制和far規范后,指定一個優化性能指標,選擇合適的路徑約束,然後再解最優控制問題。
  3. By analysis of frequency spectrum based on matlab platform, wavelet method in the application of cutting out a section of inputting earthquake wave was presented. in the process of pseudo dynamic test results, the method of non - dimensional representation and analytic representation of hysteretic curve was provided. the above two methods will help to compare dissipation energy capacity of this structure at the different acceleration peak value stage of pseudo dynamic test more precisely and comparably
