Inside Nastran, Answer 146 provides superior dynamic evaluation capabilities, together with the flexibility to compute Absorbed Energy (typically known as “abar”) utilizing Frequency Response Capabilities (FRFs). This course of includes making use of calculated forces derived from measured or simulated vibrations (represented by FRFs) to a structural mannequin. By calculating the facility dissipated by damping at every frequency, engineers can acquire insights into how successfully a construction absorbs vibratory power.
This strategy supplies crucial data for noise, vibration, and harshness (NVH) analyses, serving to to determine areas of a construction which might be simplest or least efficient at absorbing vibrations. Understanding energy absorption traits is prime for optimizing designs to mitigate noise and vibration, enhance structural sturdiness, and stop resonance points. This methodology has turn into more and more necessary with the rising emphasis on lightweighting and high-performance constructions in industries reminiscent of aerospace and automotive.
