  1. Experimental investigation on vibration reduction of hull model by bubbly layer

    艦船結構氣幕減振的模型試驗研究
  2. The major work is as follows : 1 ) based on dry hull modal analysis of flexure - torsion coupling vibration of unsymmetrical ship structures about longitudinal centerline, a transfer matrix method to calculate the dynamic characteristics is adopted after the parameters of structures are specified. taken both shear effect and warping deformations into account, the point and field transfer matrices are derived, and the influence on dynamic characteristics is computed according to different damaged positions and areas

    其主要內容如下: 1 )通過薄壁梁理論求得結構參數后,採用遷移矩陣法,在考慮剪切效應、轉動慣量和翹曲影響下,推導出求解破損船體結構的動態特性公式系統的場遷移矩陣和點遷移矩陣,並著重分析了船體不同破損程度和翹曲變形對船體振動的動態特性的影響。
  3. This paper is aimed to provide a computational method of sound radiation from the pressure and non - pressure hulls of submarines subjected to harmonious point forces. it is significant for reducing vibration and sound radiation of the submarine hull, guiding the optimization design of submarine and enhancing its battle ability

    本文尋求潛艇耐壓和非耐壓船體結構受激振動輻射噪聲的計算方法,分析潛艇結構輻射噪聲的影響因素,對降低艇體振動和輻射的噪聲,以及潛艇結構進行隱身優化設計、提高其戰鬥力具有十分重要的理論指導意義。
  4. The element leading to problems could be extremely complicated, for instance, insufficient consideration during the model setup ; certain affecting elements vary with different types of ship, like the ship hull deformation, shaft vibration and reinforcing hardness and so on ; inadequate accuracy control and errors during the construction

    導致問題的因素相當復雜,有計算模型的建立過程考慮因素不周;也有一些影響因素的特定性,對于不同的船型而不同,如船體變形,軸系振動,支座剛度等;還有施工過程精度控制不夠或施工過程出現錯誤。
  5. If you add to this the effects of a sonar set mounted in the small nose of a torpedo rushing through the water at speeds up to 80 miles per hour with its consequence noise and vibration, plus hull borne vibrations from the power plant, it can be seen that only the most advanced electronic filtering gives any chance of success

    如果再加魚雷在水中以每個小時高達80海里的速度前進時所產生的噪聲和震動對安裝在小小雷頂聲納的作用,加之動力裝置所產生的殼體振動,就不難看出,只有最先進的電子濾波才可能有成功的機會。
