频率分析允许计算设计的自然（谐振）频率和相关形式的振动。它可用于检查工作频率范围内的谐振频率，并优化设计，防止谐振的出现。因此，开发人员可以提高设计的可靠性和效率。 在频率分析的参数中，确定要确定的自然频率数。系统可能无法修复（空间可用）。谐振频率的计算考虑到作用于结构的力（例如重力）。 因此，频率和它们自己的振动形式被推导出来。 自然频率对应于结构的预期谐振频率。 形状波动（模式）显示相对变形（位移），在对应的自然频率下，该变形（位移）将发生共振。应当记住，后处理器窗口中显示的振动形式仅代表振荡的相对振幅。分析这些形式，您可以得出关于谐振位移的性质的结论，但无法得出其实际振幅的结论。例如，了解特定自然频率的预期振动形式，可以在设计领域指定与这种振动的峰值相对应的额外紧固或支撑，导致产品光谱特性的有效变化。
