Table 2 Predicted major characteristics of QZS vibration isolator with spring stiffness error and assembly error
|
|
| Error | Maximum vibration transmission rate | Valid vibration isolating frequency range | | 0% | 15.08dB | > 5.6 Hz | | 5 % error of spring stiffness | 19.97 dB | > 13 Hz | | 10% error of spring stiffness | 26.16db | > 21 Hz | | 0.144 mm assembly error(the preload of the linear spring is 0.02N smaller than the gravity of isolated mass) | 20.46 dB | > 11 Hz | | 5 % error of spring stiffness plus 0.144 mm assembly error | 28.22 dB | > 17 Hz |
