文章采用动力学响应对比方法研究LNG船绝缘层对晃荡载荷的缓冲效应。首先引入缓冲系数概念,然后建立No96型LNG船液货舱有绝缘层模型和无绝缘层模型,通过晃荡软件计算晃荡载荷,对比两种模型在相同晃荡载荷下的动力学响应,得出缓冲系数,并通过讨论晃荡载荷参数确定No96型LNG船舷侧处绝缘层缓冲系数的范围。
文章採用動力學響應對比方法研究LNG船絕緣層對晃盪載荷的緩遲效應。首先引入緩遲繫數概唸,然後建立No96型LNG船液貨艙有絕緣層模型和無絕緣層模型,通過晃盪軟件計算晃盪載荷,對比兩種模型在相同晃盪載荷下的動力學響應,得齣緩遲繫數,併通過討論晃盪載荷參數確定No96型LNG船舷側處絕緣層緩遲繫數的範圍。

The comparison method of dynamic response is applied to analyzing the buffering effect of insu-lation system on sloshing load in LNG tank. The buffer coeffient is introduced, and the FE models with the insulation system and without the insulation system of a No96-type tank are built. The buffer coeffient is obtained by comparing the dynamic response of the two models under the same sloshing load which is cal-culated by sloshing software. Furthermore, the buffer coefficient’s range of insulation system on the No96-type LNG shipboard is determined by using different sloshing load parameters.
