预报动力学环境的好帮手

文章旨在介绍一个航天器工程设计工具--VISPERS.与其他软件相比,该软件有许多特色.首先,它可以在航天器初步设计阶段进行声振、振动、冲击分析,并直接输出部件级或系统级试验规范曲线.第二,使用方便、快捷、直观.第三,它可以提供其他动力学环境分析(如火工品冲击、疲劳寿命分析).第四,预报结果可信.第五,引入由知识内涵编制的专家系统.最后,提供一个火工品冲击损伤可能性的例子,说明该专家系统的应用价值.

VISPERS: a useful tool for predicting dynamic environments

This paper introduces VISPERS,an engineering tool for spacecraft design.It has many unique features.First,itis capable of condueting a preliminary vibroaeoustic and shock analysis in an early phase of spacecraft design.Second,it Provides easy,quick and user-friendly operations.Third,it also.provides other dynamic analyses as pyroshock and fatigue life analysis.Fourth,it gives reliable results by minimizing inherent complexities and uncertainties in predietion.At last,the tool incorporates a knowledge-based expert system for extended performance,In the end,an example is given about pyroshock damage hazard analysis to show the applieation of the expert system.
