CSR和CSR-H的焊接系数研究

归纳和定性分析CSR和CSR-H的焊接系数,确定焊接系数的影响因素。提出焊接系数利用因子的有限元分析方法,确定焊缝强度的应力标准。进行了13艘CSR船舶船体结构焊缝应力的提取和焊接系数利用因子的计算,获得CSR船体结构各类角焊缝利用因子的统计结果。通过短柱和板条梁的焊缝强度试验,验证焊缝强度标准及焊缝应力公式的正确性和适用性。

Welding coefficients in common structural rules and harmonised common structural rules

Welding coefficients in common structural rules (CSR) and harmonised common structural rules (CSR-H) have been induced and qualitatively analyzed to determine the influence factors. FEM analysis method of utilization factors of welding coefficients is presented to set up the stress standard of weld strength. It carries out the extraction of welding stresses and the calculation of the utilization factors of the welding coefficients according to the hull structures of thirteen CSR ships to obtain the statistical results of the utilization factors of the various fillet welding of CSR ships. The accuracy and applicability of weld strength standard and weld stress formula are validated through the weld strength tests of the stub and batten girder.
