Anti-slip type high temperature sensor pressurized installation device

Abstract

The invention discloses an anti-skid type high temperature sensor pressurizing mounting device, and relates to a device for installing a high temperature sensor. The device comprises a support plate used for placing a sensor test piece and a pressurizing bracket used for adjusting the position of the sensor test piece on the support plate. A plurality of pressurizing assemblies for pressurizing the pressurizing point on the sensor test piece are mounted on the pressurizing bracket. Each pressurizing assembly comprises a pressurizing ejecting rod and a pressurizing ejecting block. The pressurizing ejecting rod is mounted on the pressurizing bracket. A pressurizing sheet covering the surface of the sensor test piece is connected on one end of the pressurizing ejecting block. The other end ofthe pressurizing ejecting block is connected with the pressurizing ejecting rod. An anti-loosening limiting mechanism used for preventing loosening between the pressurizing ejecting rod and the pressurizing ejecting bracket is also arranged between the pressurizing ejecting rod and the pressurizing ejecting bracket. The pressurization reliability in the sensor mounting process can be guaranteed and the device has the advantages of flexible design, simple structure, convenient operation and high sensor mounting reliability.

Description

technical field [0001] The invention relates to a device for installing a high temperature sensor, in particular to an anti-slip type high temperature sensor pressurized installation device. Background technique [0002] At present, most aircraft front-end structures are hemispherical and conical, and the materials used are mostly ceramic materials, fiber-reinforced resin-based composite materials and other materials with high temperature resistance and low thermal expansion coefficient. Ground thermal tests are usually used to assess the performance of such structures Thermal comprehensive performance, which analyzes structural performance by collecting data using high-temperature sensors during testing. Due to the special shape and material of the front end structure of the aircraft, there are many problems in the pressurized installation of the high-temperature sensor in the ground thermal test. The surface-mounted high-temperature sensor of ceramic material or composite ...

Problems solved by technology

[0003] The ground thermal test of the aircraft is the main means to assess the structural response and failure mechanism of the aircraft structure in a thermal environment. Due to the particularity of the thermal test, the general structure cannot be repeatedly tested, so the reliability of the data measurement in the test is extremely high. However, the current high-temperature sensor pressurization installation methods are quite different, so there is an urgent need for a high-temperature sensor pressurization installation device to improve the reliability of thermal test data acquisition
