Foreword

GB/T 28878 "space science experimental rotating parts specification" is divided into the following 10 parts. - Part 1. Design principles; - Part 2. Lubrication design requirements; - Part 3. Rolling bearing acceptance; - Part 4. acceptance of lubricants; - Part 5. Motor acceptance; - Part 6. Performance testing; - Part 7. Reliability testing; Part 8. Assembly; - Part 9. Delivery; - Part 10. Storage reinspection. This part is part 7 of GB/T 28878. This part is drafted in accordance with the rules given in GB/T 1.1-2009. This part is headed by the National Committee for the Standardization of Space Science and Its Application (SAC/TC312). This part of the drafting unit. Shanghai Institute of Technical Physics, Chinese Academy of Sciences. This part of the main drafters. Yang Yi, Wang Weicheng, Wang Chenfei. Specification for rotating parts of space science experiment Part 7. Reliability tests

1 Scope

This part of GB/T 28878 specifies the reliability test items, methods and procedures for the rotating parts of space science experimental installations, The condition of the test, the method of the test cycle and the implementation of the reliability test. This part is applicable to the reliability test of the ground of the rotating parts of the space science experimental device. Other payloads and spacecraft are flat The reliability test of the rotating parts of the table can be made with reference.

2 normative reference documents

3 test classification and project

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 Reliability level test, life verification test content in Table 1. Table 1 Test classification and content Test category test content 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
