摘要
在ANSYS环境中,首先建立了某7m口径圆抛物面天线的数字化模型;然后在自重和稳态风荷作用下,对天线进行了静力学分析,验证了天线的设计刚度和强度;最后计算了天线的前20阶固有频率和振型,分析了天线的动态特性,为改进和优化设计提供了依据。
In this paper a digitized model has been established for a 7m diameter circular paraboloid antenna firstly under the ANSYS circumstance; then under the action of dead load and steadystate wind load, we make static mechanical analysis, to verify the designed rigidity and intensity of antenna; lastly analyzing and calculating the inherent frequency and vibration mode of first 20 orders, we provide a basis for improving and optimizing the antenna design.
