区间参数梁结构热弹耦合效应分析
Analysis of thermo-elastic coupling effects of the beam structure with interval parameters
摘要
Abstract
The dynamic response of thermo-elastic coupling of the beam structure with interval parameters is studied under both the thermal load and force load.The dynamic model of thermo-elastic coupling is set up using the finite element method.The coupled calculation method is proposed for solving the transient temperature field and dynamical response by iterative solution,in which the finite difference method is used for solving the transient temperature field,and time integration method is used for solving structural dynamic response.The equations for the model with interval parameters are solved by the improved Monte Carlo numerical simulation method assuming that each variable is uniformly distributed,and then the interval distribution range of the dynamic response is determined.Finally,the thermo-elastic coupling effect on the dynamic response of the cantilever beam is analyzed.Numerical examples show that the thermo-elastic coupling effect is mainly determined by the increased interval range of the elastic modulus and thermal expansion coefficient influence and the magnitude of deformation.关键词
