高精度目标跟踪系统地基环的力学分析

Mechanical analysis of foundation ring for high-accuracy tracking systm

对高精度目标跟踪系统及地基环建立了结构分析模型,采用I-DEAS软件对地基环作了静 力分析,求出了系统前五阶固有频率和振型。从理论上对各振型进行了分析,分析结果表明,整个系统具有较高的固有频率,有较强的抗振性,地基环的强度和刚度能够满足要求,从而为实际工程提供了设计依据。

The structure and analysis model for a high-accuracy target tracking system and its foundation ring is established. The first 5-order inherent frequency and vibration models have been obtained through the mechanical analysis for the foundation ring carried out with I-DEST software. The analysis for various models is carried out in theoretically. The analysis results show that the whole system has a higher inherent frequency and stronger vibration resistance. The strength and rigidity of the foundation ring can meet the demands, thus providing design basis for the practical project.
