Abstract

The invention belongs to the technical field of sensor tests in the aviation industry, and specifically relates to a linear displacement sensor test device applicable to the high and low temperature environment. According to the device, a stator is fixed in a high and low temperature test box through a stator installation support, a rotation system is provided with a rotor installation support, a rotor is fixed on the rotor installation support, the rotation system can drive the rotor to rotate, and the coaxiality between the stator and the rotor is adjusted; an elevating system is connected with the rotation system, and the rotation system can be driven to move in the vertical direction so that vertical movement of the rotor of the rotation system in the high and low temperature test box can be realized; a base serves as the common reference of the whole test device and has a support effect on each part; and horizontal adjustment of the whole test device is realized through leveling anchors. According to the device, the high and low temperature test environment is simulated, high-precision relative movement of the stator and the rotor of a linear displacement sensor is realized, artificial rough adjusting process during the test is cancelled, and automation of the test process is realized.

Description

technical field [0001] The invention belongs to the technical field of sensor testing in the aviation industry, and in particular relates to a testing device for a line displacement sensor suitable for high and low temperature environments. Background technique [0002] In recent years, with the rapid development of the aviation industry, sensor technology, as one of the three pillars of the modern information industry, has been widely used in many aspects of aircraft development. In the aircraft system test, the linear displacement sensor is the key link to obtain the test information, its static performance and the accuracy of the test data directly affect the performance of the flight system and the validity of the data. [0003] According to the requirements of the flight test, the linear displacement sensor is mainly divided into two types: single redundancy and redundant degree. The number of channels in the sensor and the number of installed inductive elements determi...
