2016-11-10 The vibration isolation ratio of the clutch can be obviously increased within the whole speed range (700~3500 rpm) with decreasing the first, second hysteresis (H 1, H 2) and second torsional stiffness (k c 1), or increased within the high speed range (2500–3500 rpm) with decreasing J 1 or increasing J 2 (moment of inertias); (2)
The purpose of this study is to investigate the characteristics of vibration isolation system with a single degree-of-freedom (SDOF) and a two-degree-of-freedom (2DOF) respectively based on the high-static-low-dynamic-stiffness (HSLDS). This model consists of a simple configuration connecting a vertical spring and a pair of oblique springs.
In this study, a vibration isolator is designed to reduce the micro-vibration generated by the control moment gyroscope using the viscoelastic material. A mathematical model, which can describe the performance of the isolator is established in six degrees of
2019-11-7 According to the vibration isolation theory, considering M and K are load capacity and stiffness of vibration isolator, respectively, it can provide efficient attenuation when the frequency of external disturbances is higher than \( \sqrt 2 \) times the resonance frequency of the isolator. To improve vibration isolation performance of the isolator, the stiffness has to be decreased and the load capacity of the vibration isolator
2014-5-16 vibration isolation system exists in the frequency band of 10~20 Hz, vibration in the middle and high frequency band can be absorbed, and the vibration in its natural frequency range can be amplified. Based on the results, it can be seen that elastic bearings can be used to isolate vibration in the region where the environmental vibration needs to be controlled rigorously.
2002-5-28 Minimizing the vibration transmission generally involves using isolator springs and/or inertia blocks. The basic principle is to make the natural frequency of the machine on its foundation as far below the excitation frequency as possible. The mathematics for this case, and isolator selection procedures are discussed in the next sections.
Vibration isolation is a commonly used technique for reducing or suppressing unwanted vibrations in structures and machines. With this technique, the device or system of interest is isolated from the source of vibration through insertion of a resilient member or isolator.
