• 中文摘要： 本文?討船舶在不規則海面上行駛時，承受波浪衝擊力之統計動力分析。Ochi氏曾試驗及討論波浪衝擊力之自然性質及船舶承受波浪衝擊力之統計資料分析。本文以有限梁元素作?船舶結構之模擬，以正態振動模式函數來決定船舶之振動特性及動力反應。波浪衝擊力以不穩定過濾性包生過程來處理，則動力反應過程可以將此輸入過程通過船舶系統轉換求得或利用馬可夫過程，文中以525呎長美國標準散?貨輪"SS Gopher Mariner"?例，計算船舶承受波浪衝擊力之統計動力反應。
• 英文摘要： A stochastic theory of ship dynamics due to slamming impacts in random seas is presented. The nature of slamming impacts and the statistical characteristics of ship slamming have been extensively studied by Ochi. Finite-beam elements with lumped parameters are used to idealize the ship system. The vibration characteristics and the dynamic response can be determined by normal-mode approach. The slamming impacts as the input to the ship are treated as a nonsta-tionary filtered poisson process. The output (response) process can be determined by passing such a nonstationary process through the time-invariant ship system or using a Markov process. The 525 foot long "SS Gopher Mariner" is used as an example for the slamming response calculation.
