The storage device of computer information product becomes a basic equipment nowadays. It brings convenience (e.g. ATM, Pronunciation service system, Easy card automated system, etc) to our life. Industry computer plays an important role in the business. The computer not only has simple function, but also controls the whole operation flows in the factory. Hence, it can not be interrupted or crashed during the operation. And the computer must have high storage system with security and stability. Therefore an anti-vibration mounting is needed unlike the personal computer. The mounting protect the data transmission to avoid date lost from interrupted or crashed by external power or vibration of machine operating.
This thesis is to investigate the effect of the transmission efficiency when the disk system (hard disk) is reading at acclivitous angle. The performance of transmission efficiency has been noted when the disk system subjected by the vibration at different inclined angles. The method can be discussed into two parts. Firstly, compare with different angle, different vibration level, and different vibration rate, the transmission efficiency has good results when it is 160Hz, any angles, Isolator 20A. Secondly, the transmission efficiency has better effect when it is 160Hz , at any angle, complex Isolator 8A40A at different angle, different vibration level, different vibration rate comparability with different complex Isolator. At last, comparing with different angle, different vibration level different vibration rate, different Isolator VS different angle, different vibration level, different vibration rate, different complex Isolator, the best transmission efficiency is 160Hz, at any angle, complex Isolator 8A40A.
