Extracting method of structural modification area using mutual modal kinetic energy distribution and effect of vibration reduction by tuned natural frequency
Transactions of the JSME (in Japanese)
Computer-aided engineering is widely used in mechanical engineering to analyze the noise-and vibration-related performances of components and assemblies. Recently, extremely fine meshes of the body structure and large number of degree-of-freedom (DOF), in a finite element model (FE model) with increased CPU power, have been used to run simulations in high-frequency regions and to improve the accuracy of the simulations. This FE model is better suited for studying the effects of changingdoi:10.1299/transjsme.19-00062 fatcat:5aqshrv7rvg6vl4r4zsprzyj5m
