RISResearch on the Interior Noise Reduction of an Elastic Cavity by the Multipoint Panel Acoustic Contribution Method Based on Moore–Glasberg Loudness Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: More and more attention has been paid to reduce the low frequency interior noise of the elastic cavity, such as automobiles, ships, airplanes, and railway vehicles, to provide the more comfortable riding environment for ...
Numerical Evaluation of High Order Modes for Stepped Beam
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The numerical evaluation of highorder modes of a uniform Euler–Bernoulli beam has been studied by reformatting the classical expression of mode shapes. That method, however, is inapplicable to a stepped beam due to the ...
Modeling Hypervelocity Impact Induced Shock Waves for Characterizing Orbital Debris Produced Damage
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Hypervelocity impact (HVI) is a scenario involving an impacting velocity in excess of 1 km/s. Ubiquitous in outer space, paradigms of HVI are typified by the collision between orbital debris and spacecraft. HVI features ...
A Dynamic Equilibrium–Based Damage Identification Method Free of Structural Baseline Parameters: Experimental Validation in a Two-Dimensional Plane Structure
Publisher: American Society of Civil Engineers
Abstract: A damage identification method named the pseudoexcitation (PE) approach was established previously, the principle of which resides on local examination of perturbation of structural dynamic equilibrium conditions. While ...
