Description
Technical Field
The utility model relates to a sensor mounting base, especially a can instruct sensor mounting base for vibration test of installation angle.
Background
At present, various sensors are generally needed for detecting information such as position, angle, speed and the like in a vibration test on an aircraft, and the vibration test requires that the sensors perform a test in a horizontal direction or a vertical direction. During vibration, the vibration sensor is installed on the test piece through the sensor installation base, and the installation direction of the vibration sensor is consistent with the vibration direction. Since the test piece surface at the sensor mounting position is not all parallel or perpendicular to the vibration direction, it is necessary to determine whether the sensor mounting direction coincides with the vibration test direction when the sensor is mounted on the test piece surface.
Conventionally, a known sensor mounting base for a vibration test does not have a mounting angle indication function. Therefore, it is often observed by naked eyes to determine whether the sensor mounting direction is consistent with the vibration test direction. Because the sensor mounting base is small in size, the judgment method is greatly influenced by subjectivity, and the obtained result is often not accurate enough. Especially, when the space of the sensor mounting position is limited, especially in a crack, a proper visual angle cannot be found through visual observation, and whether the sensor mounting direction is accurate or not is more difficult to judge.
