| 摘 要： | 针对全船结构强度直接计算中，波浪加载较为麻烦的问题，提出了一种ANSYS环境下的波浪压力自动加载的方法。该方法将三维水动力程序计算的船体表面的波浪压力经过插值算法转换到有限元结构单元上，压力数据文件读入ANSYS实现了自动加载。最后，利用该自动加载方法对一艘穿浪双体船进行加载。结果表明，该方法将波浪载荷计算和结构强度分...

| Abstract: | Since wave pressure loading in the direct calculation of overall ship structural strength is a time-consuming job,an automatic loading approach in the ANSYS environment was proposed.Using this method,wave pressure on ship surface calculated by 3D hydrodynamic program was transferred to Finite Element model by interpolation algorithm.The pressure data file was read into ANSYS to fulfill the automatic loading process.The automatic approach was applied to a wave piercing catamaran as an example.The results sho... |
