Guidelines for Margin Design of Aerospace Products1 ScopeThis document provides general rules for aerospace product margin design, environmental margin design, structural mechanism margin design, electronic circuit margin design, thermal Recommendations on protection margin design and software margin design, and related information are given. This document is applicable to the margin design of launch vehicles and spacecraft products. Other aerospace products can be used as reference.2 Normative referencesThe contents of the following documents constitute the indispensable clauses of this document through normative references in the text. Among them, dated quotations Only the version corresponding to that date is applicable to this document; for undated reference documents, the latest version (including all amendments) is applicable to This document. GB/T 32296 Spacecraft commonly used coordinate system GB/T 32452 Spacecraft Space Environment Terminology GB/T 32455 Terminology for launch vehicles3 Terms and definitionsThe following terms and definitions defined in GB/T 32296, GB/T 32452 and GB/T 32455 apply to this document. 3.1 Margin Characterize the degree of margin between the design value and the demand value. 3.2 Radiation design margin radiationdesignmargin; RDM The ratio of the radiation resistance of the product to the predicted radiation dose in the working environment.4 General4.1 Basic principles The reliability margin design of aerospace products is used to compensate various uncertainties in product production and use, and to improve product reliability. conduct The basic principles of margin design generally include. a) Comprehensive design, manufacturing, testing, use, maintenance and other constraints of the entire life cycle of aerospace products, taking into account the advanced nature; b) Considering the different characteristics of aerospace products, adopting the corresponding generalized margin design, generally considering the environment (including heat protection, mechanical resistance, radiation resistance, Electromagnetic interference, etc.) margin, strength margin, drive margin, life margin, electronic circuit margin, software design margin, etc.; c) Attach importance to stress-strength interference analysis, adopting methods such as improving average strength, reducing average stress, avoiding stress concentration, and reducing strength dispersion, etc. Method to find the best match between stress and strength; d) Consider the limit design situation, including the worst case and combination of various parameters; e) Effectively evaluate and verify the margins of aerospace products. For those that have not been fully tested and verified and have poor consistency, it is recommended to use relatively Large margin. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 40537-2021_English be delivered?Answer: Upon your order, we will start to translate GB/T 40537-2021_English as soon as possible, and keep you informed of the progress.
