摘要 通过有限元仿真和试验的方法研究了碳纤维复合材料滑动舱门的刚度,对滑动舱门在气动载荷作用下的计算与测量变形值进行了对比分析。结果表明:试验及仿真两种方法测得的复合材料舱门的变形量随着载荷的增加都呈线性变化趋势,两种方法得到的位移值很相近,位移实测最大、最小值分别为13.98 mm、2.26 mm,误差为14.2%,理论计算值分别为12 mm、2.19 mm,误差为3.1%。验证了仿真分析方法及试验方法的合理性。不同位置内外面板高度的不同对舱门的刚度有显著影响,其原因是高度的差异影响了舱门抗弯承载能力,而舱门主要受面外载荷,因此舱门刚度取决于其抗弯承载能力。

Abstract: In this paper, the stiffness of carbon fiber composite sliding door was studied by means of finite element simulation and test. The calculated and measured deformations of sliding door under aerodynamic loads were compared and analyzed. The results showed that the deformation of the composite door under the two methods of test and simulation showed a linear trend with the increase of load. The displacement values obtained by the two methods were very similar. For example, the maximum and minimum displacement actual measured value were 13.98 mm and 2.26 mm, with an error of 14.2%, and the theoretical calculation values were 12 mm and 2.19 mm, with an error of 3.1%. The rationality of simulation analysis method and test method was verified. The stiffness of the door was significantly affected by the height of the inner and outer panels at different locations. The reason is that the height of the door affects the flexural capacity of the door, and the door is mainly subjected to the out-of-plane load. Therefore, the stiffness of the door depends on its flexural capacity.
