Vibration And Dynamic Analysis


Vibration of structures and manufactured products can lead to many functional problems including fatigue and fracture failures. Vibrations may cause occupants and bystanders concern about the integrity of structures and machinery.

Predicting vibrations or dynamic characteristics of structures and manufactured products in new designs, affords the designer the opportunity to adjust the design, if unacceptable vibrations or dynamics are predicted. Predicting unacceptable vibrations or dynamic characteristics of existing structures or products will allow the owner to seek modifications to the structure or product aimed at reducing or eliminating those unacceptable vibrations or dynamics.

Analysis Capabilities

Modal analysis - determine the resonant frequencies and mode shapes of a structure or product.
Impact analysis - determine the deformations and stresses generated in a structure or product when dropped or impacted.
Harmonic analysis - determine the deformations and stresses generated in a structure or product due to a harmonic loading, such as an unbalanced motor or tire.
Transient dynamic analysis - determine the deformations and stresses generated in a structure or product due to time varying structural and/or thermal loading.
Spectrum analysis - determine the deformations and stresses generated in a structure or product imposed with a response or design spectra of frequency-load amplitudes.

Applications

Reduce or eliminate potential deformations and stresses generated by structural vibrations and dynamic events.
Reduce or eliminate potential deformations and stresses generated from rotating machinery.
Modify the response of structures to extreme environments such as impact, high winds, and earthquakes.
Modify the response of equipment to a vibrating environment.
Modify structures and manufactured products to reduce or eliminate detrimental vibration and dynamic behavior.
