Overload environment thermal centrifugal test device

Abstract

The invention belongs to the simulation test technological field and relates to an overload environment thermal centrifugal test device. The device comprises a centrifuge body and a heater; the centrifuge body comprises a test chamber; a test piece fixing device for fixing a test piece is arranged in the test chamber; the heater is arranged in the test chamber; the heater comprises a quartz lamp heating component; and the quartz lamp heating component is used for simulating a thermal load borne by the test piece. According to the overload environment thermal centrifugal test device of the invention, a centrifuge is adopted to simulate an overload load, a corresponding loading curve is set according to test requirements, and therefore, the overload load can be accurately loaded, long-term operation can be realized; the quartz lamp heating component is adopted to apply the thermal load, so that the joint loading of the overload load and the thermal load can be realized; the heater is installed in the test chamber of the centrifuge body, so that the simultaneous application of heating and centrifugal overload can be realized; the applied thermal load and overload can be accurately controlled; the reliability of the heater in a centrifugal environment can be increased, and therefore, it can be ensured that long-term and high-power heating can be performed in the overload environment of the centrifuge.

Description

technical field [0001] The invention relates to the technical field of simulation tests, in particular to an overload environment thermal centrifugal test device. Background technique [0002] During launch and flight, aerospace vehicles will face overload and thermal environment. Under the influence of overload and thermal environment, aircraft products may fail. The thermal overload assessment test of conventional structures is usually assessed in the form of "static load + thermal load" test. For structures with internal coordinated deformation, the static heat test method with external force cannot truly simulate the internal stress state of the structure. test method. At present, the existing test system that can simulate the "overload + heat" combined load is the "thermostat + centrifuge" test system, which uses a thermostat for temperature loading and cannot simulate rapid transient temperature changes. At the same time, the maximum temperature that can be applied is...
