Abstract |
|
In space engineering, the prediction of structural responses induced by
pyrotechnic devices is important for protecting the space hardware, especially the
electronic components. This paper presents a fast simulation of pyroshock responses
of a conical space structure. Firstly, a finite element analysis was performed and the
responses to a load element were obtained. Then, by introducing the quick method,
Rotation-Superposition Method, the structural responses induced by various numbers
of explosive bolts were predicted and the effects of non-simultaneous initiations were
also analyzed. This study provides a high-efficiency approach for multi-case
pyroshock responses prediction |
