GB/T 28878.7-2016Specification of the rotating component in space science experiments—Part 7: Reliability test (English PDF)

3.1 Overview

The reliability tests involved in this section include the design (process) verification test, the initial stage or the stage of the reliability index verification test,

Proof stage, or product batch stage reliability level verification test and life verification test. The planning, implementation and evaluation of the reliability test shall be consistent

GJB451 and GJB899 requirements.

Among them, the design (process) verification test, the initial stage or the stage of the reliability index verification test, the positive stage or product batch stage can be

Design (craft) verification test

In the design phase, the use of sampling test program, in the laboratory simulation using the task profile encountered the most harsh environment

And the working conditions, that is, the identification of test conditions appropriate to tighten, apply stress.

The newly developed rotary parts shall be tested and shall be tested on reliability, reliability verification and life verification

Before the test. This test may be carried out in conjunction with the engineering development of the parts or the machine

Initial stage or stereotypes

Segment reliability index verification test

In the design of the styling stage, the use of sampling test program, in the laboratory simulation using the task profile encountered the worst ring

Environment and working conditions, stress applied.

This test may be carried out in conjunction with the identification test of the part or the machine. When the design (process) after the change should be re-enter

Line reliability test

Positive stage or product batch

Stage reliability level test

Test

During the batch production phase, a full test (100% sampling) scheme was used to simulate the use of the task profile in the laboratory

To the actual environment and working conditions, to apply stress.

This test may be carried out in conjunction with the verification test of the part or the machine

Life verification test

In the development phase, the use of sampling test program, in the laboratory simulation of the use of the task profile encountered by the actual environment and work

Condition, stress applied. If necessary, the product can be sampled before and after the delivery of the product for life verification test.

This test may be carried out in conjunction with the parts of the organization […]
