摘要

本文提出了大型抛物面天线结构风振响应分析的随机振动方法。对风荷功率谱密度函数和多自由度系统响应函数矩阵进行了推导;建立了可同时计算结构风荷静变形和动响应的统一表达式;设计了相应的计算机程序并给了一个工程算例。

Abstract

The random vibration method for the analysis of large parabolic antenna structure response to wind load is proposed in this paper. The power spactral density fonction of wind load and response function matrix of muli-degree-of-freedom system are derived. The unified calculating formulas are given

with which both the static deflections and dynamic re- sponses of structure can be gained simultaneously. A corresponding computer program is designed and an engineering calculation is given.
