Abstract

The invention discloses a high-temperature environmental vibration test method and a heat insulation switching device. The test method is carried out based on a high-temperature environmental vibration test system which comprises a high-temperature environment generation device, the heat insulation switching device, an excitation source and a circulating cooling device. A hole channel is formed inthe heat insulation switching device; a test piece is arranged on the heat insulation switching device; the excitation source provides excitation force which acts on the heat insulation switching device to drive the test piece to vibrate; and the heat insulation switching device is connected to the external circulating cooling device through a pipeline, so a circularly flowing cooling medium circularly flows in the heat insulation switching device for heat exchange, and the temperature of the excitation source is not influenced by a high-temperature environment. In this way, the test method is reasonable in design, and can meet the requirements of high-temperature environmental vibration tests at a temperature of 1200 DEG C.

Description

technical field [0001] The invention relates to the technical field of mechanical environment tests, in particular to a high-temperature environment vibration test method and a heat insulation transfer device. Background technique [0002] With the advancement and development of science and technology, people's demand for vibration testing in high temperature environments is also increasing. In this type of test, the heat in the high-temperature environment will be transferred to the excitation source through heat transfer, which will increase the temperature of the excitation source, which will affect the performance of the excitation source and make the test impossible, and cause safety hazards and safety accidents, which is very dangerous. [0003] The traditional test method is only to install heat insulation material on the output table of the excitation source to slow down the output of heat to the excitation source. This method can only be used for tests below 120 °C...
