In this paper, we propose a new method to identify the error factors between an actual structure and the finite element (FE) model. The FE model updating using sensitivity and optimization algorithm conventionally is used to ensure high accuracy. Par

It is necessary to separate the multiple resonance frequencies of a vehicle body from outstanding peaks of excitation spectrum to reduce the road induced noise of cars. A vehicle body is always excited by the transmitted forces from a chassis system,

In order to predict how much the human ligamentum flavum (LF) will be deformed during insertion of an epidural needle, the elastic modulus of a porcine LF was determined with a tensile test. LF specimens collected from porcine spines in a slaughterho

In this paper, time domain mutual mean compliance is proposed to reduce transient vehicle interior noise caused by discontinuous impact force from road surface. The interior noise is caused by coupling of structural vibration and acoustic modes. Ther
