A fiber-reinforced composite thin-shell rotational test stand considering uniformity and temperature gradient influences and under high-strength aerodynamic load excitation, relating to the field of vibration testing, and comprising an integral body structure, a fiber-reinforced composite thin-shell connecting structure at a rotating electrical machine, a connecting structure at a movable seat, an aerodynamic load excitation structure for the test stand, a heating pipe connecting seat, and a non-contact laser testing device. The present invention can realize non-contact high-strength aerodynamic load excitation and testing of a rotational fiber-reinforced composite thin-shell with regard to uniformity and temperature gradient influences. L'invention concerne un banc d'essai rotatif à enveloppe mince composite renforcé par des fibres tenant compte des influences d'uniformité et de gradient de température et sous une excitation de charge aérodynamique à haute résistance, se rapportant au domaine de l'essai de v
