Abstract

The invention relates to a thermal vibration test device and a test method based on shape-position equivalent reverse deduction control, which belongs to the technical field of thermal environment test and test, and solves the problem that the existing test technology cannot meet the vibration test in a high-temperature thermal environment. The thermal vibration test device based on shape-position equivalent reverse thrust control of the present invention includes a vibrating table, a heat source, a tooling, a temperature sensor and an acceleration sensor; the vibrating table includes a base, a vibrating table body and a vibrating table table top, It is used to load the test piece with vibration, the tooling is installed on the vibrating table for clamping the test piece, and the heat source is used for heating the test piece. The present invention realizes combined heat and vibration test by using the vibrating table top that can fix the acceleration sensor, and using the metal tooling that is in the same heating temperature zone as the test piece to fix the temperature sensor, and satisfies the test that the high temperature environment and vibration conditions are applied simultaneously Require.

Description

A thermal vibration test device and test method based on shape and position equivalent reverse thrust control technical field The present invention relates to the technical field of thermal environment test and test, in particular to a kind of thermal control based on shape and position equivalent inversion control. Vibration test device and test method. Background technique [0002] When a supersonic vehicle flies at a supersonic speed for a long time, due to the viscous friction of the air, it is subjected to severe aerodynamic stress. The thermal effect causes the surface temperature of the aircraft structure to rise, and the extremely high temperature and temperature gradient will change the thermophysics of the aircraft structure parameters and mechanical properties, resulting in changes in the mechanical properties of the aircraft structure, resulting in structural bending and torsional stiffness It has a serious impact on the strength, stability and control of t...
