The theoretic of calculate the react force act on the launching way also be investigated 對74500噸散貨船下水時的滑道反力進行了實船計算。
The detail analysis of force act on hull and launching way are discussed for each stage in this report 對每個階段船體的受力情況和滑道壓力進行了分析,并對滑道壓力的理論計算方法進行了闡述。
In order to resolve the strength problem of 74500dwt bulk carrier on launching way , two aspects of problem are investigated in this report : 1 ) the analysis and calculation of the force act on the hull and the launching way when ship launching ; 2 ) the strength analysis and calculation of bottom structure in forward area during ship launching 為了解決74500噸散貨船下水時船體結(jié)構(gòu)的強度問題,本文主要對兩方面的內(nèi)容進行了研究: 1 )船舶縱向下水時的受力分析和滑道反力計算: 2 )艉浮時艏部區(qū)域底部結(jié)構(gòu)強度分析計算。
