| Abstract: | In different flight postures and flight conditions,the intelligent structure and actuator of a morphing wing may perform dynamic deformation as required by external conditions and control commands,which demonstrates its good aerodynamic property.Due to the complicated and varied conditions of distribution and function of the stress field and the temperature field of the wing body structue,it is necessary to perform a coupling analysis of multi-physical fields to obtain accurate information of the strain dis... |
