3 Terms and definitions
The following terms and definitions as defined in GB/T 32303 apply to this document.
3.1 Basic data
Input data required to perform stress analysis and determine safety margins.
3.2 Specification size gauges
Structural dimensions that have a significant effect on the stress level and/or safety margin, such as the thickness of the sheet, the width and thickness of the profile edge.
Degree, the height and thickness of the web.
3.3 A-reference value A-basisalowable
The confidence level is 95%, covering at least the mechanical strength value of the 99% parent value.
3.4 B-reference value B-basisalowable
The confidence level is 95%, covering at least the mechanical strength value of the 90% parent value.
3.5 Minimum allowable value
The minimum material mechanical properties guaranteed by the supplier.
3.6 Primary structure
The structural components that bear the primary load and determine the base frequency of the launch vehicle and spacecraft.
3.7 Semi-finished
For structural fabrication or assembly, there is no final product. […]
