All physical bodies have particular frequencies at which they will readily vibrate. The ability to predict these natural frequencies and the associated mode shapes is crucial to numerous areas of engineering. For many years approximate hand calculation methods have been available to estimate the value of fundamental and higher modes of vibration for simple structures but these methods have always had very limited applicability.
FEA vibration analysis allows detailed calculations of natural frequencies and mode shapes to be conducted for assemblies of practically any level of complexity, quickly and easily. In addition to identifying modes of vibration, forced vibration analysis can be conducted to determine the response of a structure to various types of excitation loading.
Typical forms of forced vibration analysis include:
• Harmonic Analysis
• Random Vibration Analysis
• Response Spectrum Analysis
• Full Transient Dynamic Analysis
Once the forced response of the system has been calculatd, then a stress analysis can be carried out to determine the stresses and deflections through the system. FEA analysis provides the ability to conduct comprehensive, automated, multi-point optimisation of designs. This process allows engineers to automatically optimise a design to a given set of performance parameters and can be used to tune natural frequencies, mode shapes and system response, stress levels and fatiguie life to given targets.
