摘要:
基于力学模型初步确定盖板结构几何参数,建立三维模型导入有限元软件HYPERMESH进行静载荷应力分析。对于结构应力集中处引发的应力奇异问题,结合弹性理论分析应力奇异产生的原因,提出减小圆环压板厚度、设置肋板圆角过渡及增加撑脚等措施来优化分析模型。优化结果显示应力集中程度减弱,最大等效应力减小,压力传递均匀,整体重量降低9.5%。实际使用过程中满足要求,验证了理论分析的正确性,为肋板焊接类结构设计及分析提供参考。
Abstract:
Determined initial geometry parameter based on mechanical model, established the 3D-model and imported it into HYPERMESH software to carry on static stress analysis. In order to solve the stress singularity problem at the stress concentrate position when adopting the finite element method, combining the reason of causing stress singularity with elastic theory, putted forward specific improvement measurements of decreasing the thickness of ring plate、setting up transition fillets of ribbed slab and adding frame braces to optimize the analysis model. Results showed that the degree of stress concentrate lowered, the maximum equivalent stress decreased, the pressure transmissions were well-distributed and the whole weight was reduced by 9.5%. The cover plate meeted the requirements in the process of actual use, verified the correctness of the theoretical analysis, could provide helpful suggestions for structural design of ribbed slab.
