Problems solved by technology

[0003] However, in the traditional aerospace engineering practice, passive high-power devices such as spaceborne high-power isolators are usually small sample products, that is, they usually do not meet the conditions for mass production, so the number of test samples is small
In addition, the cost of conducting tests in the complete machine stage of navigation satellites is also relatively high

Embodiment Construction

[0041] It should be noted that components in the various figures may be shown exaggerated for the purpose of illustration and are not necessarily true to scale. In the various figures, identical or functionally identical components are assigned the same reference symbols.

[0042] In the present invention, unless otherwise specified, "arranged on", "arranged on" and "arranged on" do not exclude the presence of intermediates between the two. In addition, "arranged on or above" only means the relative positional relationship between two parts, and under certain circumstances, such as after the product direction is reversed, it can also be converted to "arranged under or below", and vice versa Of course.

[0043] In the present invention, each embodiment is only intended to illustrate the solutions of the present invention, and should not be construed as limiting.

[0044] In the present invention, unless otherwise specified, the quantifiers "a" and "an" do not exclude the scen...

Abstract

The invention relates to the technical field of aerospace, and provides a method for verifying the service life of a passive high-power device, the method comprises the following steps: providing a test sample of the passive high-power device; determining the acceleration stress of the passive high-power device; determining a life evaluation model of the passive high-power device according to the acceleration stress; testing the service life of the test sample according to the acceleration stress; and determining the predicted life of the passive high-power device according to the life test and the life evaluation model.

Description

technical field [0001] The present invention generally relates to the field of aerospace technology. Specifically, the invention relates to a life verification method for passive high-power devices. Background technique [0002] With the rapid development of navigation satellite technology, the power and service life of navigation satellites are also increasing. For example, the service life of navigation satellites of the Beidou-3 project has been increased to more than 10 years of continuous work. In order to ensure the life and reliability of long-term continuous operation of navigation satellites in orbit, it is necessary to carry out life verification and reliability tests on some key on-board devices such as passive high-power devices. Passive high-power devices such as spaceborne high-power isolators are one of the key components in satellite navigation systems. They can be used in the post-stage of power amplifiers such as traveling wave tube amplifiers to improve t...
