内河船舶波浪载荷计算预报及规律

Prediction and Law of Wave Load Calculation of Inland Ship

利用内河波浪散布图和修订波浪谱对内河系列船舶进行波浪载荷计算预报,分析内河船舶波浪载荷的规律和特点,与俄罗斯内河登记局(RRR)和法国-德国船级社(B-G)有关内河规范载荷对应的等效模数要求进行比较,并结合实船测试结果进行分析。结果表明:波浪载荷变化规律与国外同类规范一致,预报波浪载荷水平与测试结果及国外同类规范要求相当;内河船舶波浪载荷预报应考虑航速和水深的影响,载荷预报结果可以作为制定内河波浪载荷公式的基础。

Using the inland wave scatter diagram and the mended wave spectrum, the series inland ship wave loads are calculated and predicted. The rules and characteristics of inland ship wave loads are analyzed. Comparing with the equivalent section modulus of inland rules by the Russian inland Registration Authority（RRR） and BV Bureau Veritas-GL Germanischer Lloyd（B-G）, and combining with the trial test results, the analysis is done. The result shows that the wave load variation is consistent similar with the foreign rules and the test results. The level of wave loads forecast and the test results are nearly equal to those of foreign rules requirements. The wave loads forecast of inland ship should consider the impact of ship speed and water depth. The prediction results can be used as the basis of study on inland ship wave loads formula.
