| 在水声传感器研制过程和实际装机应用之前，需进行大量的试验来测试其性能及可靠性。根据水声传感器的性能测试需求，设计了能够搭载水声传感器进行水下测试的五自由度精密位移试验台，实现传感器在试验水槽内三个直线方向和两个回转角度方向上位置的全覆盖,并提出了一种可以快速检测梯形丝杠螺母传动回程误差的工程测量方法，通过软件补偿的方法来克服回程误差，实现机构运动的准确定位, 满足了低成本模式下多自由度精密定位需求。最终，应用激光跟踪仪对试验设备进行了误差检测，保证测试过程中传感器相对位置的准确性。 |

| The performance and reliability of underwater acoustic sensor must be tested by a lot of experiments both during the development process and before actual application installed. According to the test requirements, this paper designed the five degrees of freedom precision displacement experimental device which can mount underwater acoustic sensor to complete the process of testing with achieving full coverage in the experimental tank in three linear and two rotational directions. This paper introduces a new engineering measurement method that can quickly detect the location error of screw hysteresis and overcomes the hysteresis error by software compensation. Ultimately, the works of calibration and error detection for the experimental equipment have been completed with laser tracker to ensure the accuracy of the relative position of sensors in the process of testing. |
