Mechanical vibration is an important issue for mechanical fatigue failure, machinery precision, and manufacturing process. The mechanical design in domestic industry is still in structural static analysis or even just for simple mechanics calculation and neglecting the importance of dynamic analysis. On the other hand, the industrial noise problem becomes important for environmental concerns. The industry in Taiwan just notices the noise issue and yet lack of complete study in noise generation and propagation analysis so as to carry out proper action in noise protection. In fact, noise and vibration are strongly related to each other and important issues to deal with. The diagnosis and control of mechanical vibration and noise are urgent and crucial for industry. |
