Introduction
This standard belongs to China Aerospace national standards. China Aerospace national standards applicable to national standards in the field of aerospace and revision
Management, covering the management of space, space technology, space applications and services of the three fields, is to guide spacecraft and launch vehicle project management, engineering research
System, space launch services, in-orbit satellite applications based activities.
With the rapid development of China's aerospace industry, long life, high reliability, complex spacecraft emerging. Spacecraft structures provided
Design and verification process, the spacecraft modal requirements (natural frequency requirements) is the most important requirement for the structural design of the spacecraft. aerospace
Structure modal analysis is an important part of the spacecraft structural analysis plays an important role in the development process of the spacecraft structure.
This standard is to obtain a reasonable, accurate and reliable spacecraft modal results provide evidence and guidance, modal analysis of a spacecraft model
Establishing, model checking and Modal analysis for a unified standard, the purpose is to ensure that modal analysis of the process of development of spacecraft engineering
Accuracy. Spacecraft Modal computing plays an important role in spacecraft development process, such as to avoid the resonance frequency caused by coupling spacecraft
Configuration scheme selection, dynamic environment of structural failure diagnosis, equipment and so has heralded a significant impact. Current aerospace industry at home and abroad
The rapid development of various types of spacecraft are close research and development process, it is necessary to process spacecraft modal system were calculated
A provision to ensure that calculation, the validity of the analysis process standardization and results.
Spacecraft Modal Calculation
1 Scope
This standard specifies the method of calculation of modal spacecraft.
Calculation generalized stiffness matrix and generalized mass matrix is \u200b\u200bapplicable to the calculation of spacecraft and spacecraft modal interface. Cabin, assembly
Modal can be calculated with reference to use.
2 Terms and definitions
The following terms and definitions apply to this document.
2.1
Statically determinate interface staticalydeterminateinterface
When the motion can be regarded as a rigid body structure interface.
Note. The structure through the interface connected to other structures, for static interface simply by a fixed reference point for the freedom of all interfaces can be expressed freedom movement.
2.2
Idealized structure structuralidealization
The actual structure can be transformed into a performance characteristic geometric structure and connection relationship, and can effectively reflect the structure and mechanical properties into
Mechanical Analysis row in the form of process.
Note. If the member has a certain geometric features abstracted as point, line, area or volume, thereby simplifying the structure of particle mechanics, springs, rods, beams, plates and shells, and the like.
