于ANSYS对混合驱动水下滑翔器耐压壳体设计及分析
|
摘要
对混合驱动水下滑翔器的耐压壳体进行了设计计算与有限元分析。首先对耐压壳体的材料、结构进行了选择设计,然后分别对耐压壳体壁厚、失稳、变形方面进行了设计计算,从而验证了结构、尺寸确定的理论可靠性。最后,通过对混合驱动水下滑翔器的耐压壳体中最危险部分进行强度和屈曲有限元仿真,得到分析结果与设计计算结果基本一致,从而验证了耐压壳体的设计是合理的、可行的,为混合驱动水下滑翔器的实体试验提供了很大的借鉴价值。
The hybrid driven pressure shell of underwater gliders are designed and calculated with finite element analysis. First of all,the structure of shell materials were selected,then the pressure shell wall thickness,buckling,deformation are calculated,which verified the reliability of the structure,size determination theory. Finally,through the strength and buckling finite element simulation of hybrid driven most dangerous pressure shell of the underwater glider's part,the results of the analysis and calculation results are basically consistent,which proves the design of pressure hull is reasonable,feasible,provide great reference value for the hybrid driven experimental glider solid water under the water.
