It is difficult to investigate the underlying mechanisms of complex structural vibrations in automobiles and other products, even with eigenmode analysis, due to the complexity of the mode shapes.
Unit mode analysis extracts simple mode shapes, called “unit modes,” from complex eigenmodes, simplifies the understanding of vibration transmission, and clarifies the dominant vibration paths between unit modes.
ESTECH incorporate our proprietary technologies into our Nastran enhancement software, ESTECH.NAST+, and help customers identify the true essence of their problems through these technologies.
