The invention relates to the technical field of equipment testing, and provides a propeller testing device and method.The propeller testing device comprises a supporting frame, a constant force load loading assembly and a pulsating load loading assembly; the constant force load loading assembly is fixed to the supporting frame and used for applying constant force in the pulling force direction of blades of the propeller. The pulsating load loading assembly is fixed to the supporting frame and used for applying pulsating force to the upper surface of the paddle according to the set frequency, and the pulsating load loading assembly is matched with the constant force load loading assembly to complete testing of the paddle. According to the invention, there is no need to additionally measure the force applied to the blade, and the operation of the propeller reliability test is simplified, thereby improving the simulation degree of the propeller reliability test to the real working condition.
本发明及设备测试技术领域,提供一种螺旋桨的测试装置及方法,其中,螺旋桨的测试装置包括支撑框架,恒力载荷加载组件和脉动载荷加载组件;所述恒力载荷加载组件与所述支撑框架固定,用于向螺旋桨的桨叶的拉力方向施加恒力;所述脉动载荷加载组件与所述支撑框架固定,用于根据设定频率向所述桨叶上表面施加脉动力,并与所述恒力载荷加载组件配合完成对所述桨叶的测试。本发明无需额外对施加在桨叶上的力进行测量,简化了螺旋桨可靠性测试的操作,从而提高了螺旋桨可靠性测试对真实工况的模拟程度。
