The invention belongs to the technical field of propeller performance testing, and particularly relates to a propeller underwater performance testing device and method, a walking mechanism is used for being arranged outside a water tank and can linearly move in the length direction of the water tank, a mounting frame is arranged on the walking mechanism, and the mounting frame is located at the top of the water tank; the two force measuring mechanisms are arranged on the mounting frame; the upper end of the connecting rod is located between the two force measuring mechanisms, the lower end of the connecting rod extends into the water tank to be used for mounting the propeller mechanism, the connecting rod is movably arranged on the mounting frame, and the propeller mechanism can move front and back or deflect in the propelling direction of the propeller mechanism under the action of water flow or automatic propelling force during running. According to the testing device, the influence of other structures or mechanism disturbance water flow in the testing device on a measurement result can be eliminated to a greater extent, the operation state of the propeller in the deep sea environment can be better simulated, the propeller mechanism is high in connection rigidity, and the testing device is simple in structure and convenient to operate. And the test error is smaller.

    本发明属于螺旋桨性能测试技术领域,具体涉及一种螺旋桨水下性能测试装置及测试方法,行走机构用于布置在水箱外部并可沿水箱的长度方向直线移动,行走机构上设置有安装架,安装架位于水箱顶部;两个测力机构设置在安装架上;连接杆上端位于两个测力机构之间,连接杆下端伸入水箱内用于安装螺旋桨机构,连接杆活动设置在安装架上,螺旋桨机构运行时能够在水流或自动推进力作用下沿自身推进方向前后移动或偏转,两个测力机构通过连接杆测量螺旋桨机构运行状态下产生的作用力,本发明能够更大程度的排除测试装置中其他结构或机构扰动水流对测量结果造成的影响,更好地模拟深海环境中的螺旋桨运行状态,螺旋桨机构连接刚度高,测试误差更小。
