Abstract

The invention belongs to the technical field of centrifugal tests and specifically relates to a device used for a super high speed centrifugal test of a composite material. The device includes a turbine drive part 1, a to-be-tested part 2 and a positioning connection part 3. The turbine drive part 1 and the positioning connection part 3 are fixedly connected through a screw 44 and the positioningconnection part 3 and the to-be-tested part 2 is fixedly connected through a screw 45. According to the invention, a high pressure air source drives a turbine to run at a super high speed and then a to-be-tested piece is driven through a coupler to run synchronously in a low pressure / vacuum centrifugal cavity, so as to enable the to-be-tested piece to reach a specific limit centrifugal damage rotation speed. Therefore, the limit tolerance rotation speed of the test piece made of the composite material and the centrifugal tensile stress under the limit rotation speed are checked.

Description

technical field [0001] The invention belongs to the technical field of centrifugal tests, and in particular relates to a device for ultrahigh-speed centrifugal tests of composite materials. Background technique [0002] The existing device for ultra-high-speed centrifugal failure test of composite materials is mainly driven by motor, and the test piece is in the atmospheric environment, the test rise rate is low, and the blower power consumption of the test piece is greatly lost during the speed-up process. , the test takes a long time (usually up to several hours), based on the shortcomings of the existing technology, a new device for ultra-high-speed centrifugation test of composite materials was designed and developed. Contents of the invention [0003] Technical problem solved by the present invention: Aiming at the deficiencies of the prior art, the present invention provides a device for ultra-high-speed centrifugal testing of composite materials, which drives the tu...
