双曲旋转薄壳弯曲问题理论计算方法研究
Theoretical calculation method of hyperbolic rotating thin shell bending problem
摘要
Abstract
[Objective]In order to analyze the bending characteristics of a hyperbolic rotating thin shell,the complex two-dimensional mechanical problem is simplified into a one-dimensional bending problem based on Euler's Bernoulli beam theory.[Method]By analyzing the force and deformation characteristics of shells and belt beams,a structural mechanical model is established,and a double curvature rotating thin shell bend-ing differential equation is obtained by combining the physical equation of plate and shell theory with the bending differential equation of a single-span beam.An empirical formula for typical stress is proposed and its accuracy verified by an ANSYS-based simulation.[Results]The results show that the error between the simulation and the formula is about 2.3%,which demonstrates the high accuracy of the formula in predicting typical stress and verifies the correctness of the theoretical calculation method.[Conclusion]The proposed method can provide useful references for the design and optimization of similar structure.关键词
