摘要
为提高空间电池侧身装星时的安全性,防止螺钉因频繁拆装而产生多余物,针对目前空间电池某承载螺钉,在不改变原工装前提下进行了螺钉本体的YS⁃20型棒料代替与结构优化设计。对YS⁃20棒料进行了双剪切试验,采用ANSYS对螺钉结构中的3个重要尺寸参数D_(1)、D_(2)、T进行了7×7×6共294个算例水平的设计探索,采用非对称接触模型准确地模拟了螺钉组合结构的实际承载状态。通过3种综合评价方法对满足条件的算例进行了综合评价,得出T=12.2 mm,D_(1)=16 mm,D_(2)=2 mm为最终方案,对最终方案进行了应力校验与接触分析,得到了承载状态与接触状态均有优化的螺钉结构。
In order to improve the safety of the battery of satellite side mounting,and prevent the screw from producing excess due to frequent assembly and disassembly,the YS-20 material replacement and structure optimization design of the screw body are carried out under the premise of not changing the original tooling.The double⁃shear test of YS-20 bar is carried out,and the ANSYS optimization design module is used to design 7×7×6,a total of 294,calculation cases of D1,D2,T,the three important dimension parameters of screw structure.The actual bearing state of screw composite structure is accurately simulated by using asymmetric contact model.Three comprehensive evaluations are established,and the calculation examples satisfying the conditions are evaluated comprehensively.The final results are T=12.2 mm,D1=16 mm,D2=2 mm.The stress verification and contact analysis are carried out for the final scheme and the bearing state and contact state optimized screw structure are obtained.
