Abstract

The invention discloses a carbon fiber tool heating cage for a vacuum thermal test. The cage comprises two connecting rods which are arranged vertically in parallel; aluminium profiles perpendicular to the connecting rods penetrate through upper and lower ends of the connecting rods; aluminium profiles are further vertically arranged on outer sides of the connecting rods; the aluminium profiles are fixed through right-angled joints to form an aluminium framework; a plurality of specially-shaped pieces are arranged on the two connecting rods; the specially-shaped pieces and the surfaces of the connecting rods form bent space; a carbon fiber heating belt with the starting end connected at a connection port is arranged in a parallel and round manner by winding in the bent space of the specially-shaped pieces, the end point is connected onto the other connection port, a test cable is connected with the connection port, and a test current loop is formed; and the carbon fiber heating belt is made of 3K carbon fiber yarn through weaving. The cage is simple in structure and convenient to assemble, is greatly lighter than a nickel-chromium alloy heating cage, has the better electric heating infrared radiation efficiency, can meet heating requirements of various types and various sizes and has the very high universality.

Description

technical field

[0001] The invention relates to a tooling heating cage for space vehicle vacuum heat test, and the device is suitable for space vehicle ground heat vacuum test. Background technique

[0002] The heating cage is the key tooling in the spacecraft space environment simulation test. Its main function is to simulate the high and low temperature changes of the satellite in the space environment, so as to realize the evaluation of the overall characteristics of the satellite.

[0003] The traditional infrared heating cage uses a nickel-chromium alloy metal strip coated with a special high hemispherical emissivity black paint coating as the heating body. Due to linear expansion, springs must be attached to the skeleton to offset the strip under the alternating cold and heat of the thermal test. The length changes, so this type of heating cage has the problems of heavy manual workload and low efficiency.

[0004] Spacecraft vacuum thermal tests need to generate infra...
