This article considers the design of a compact isolator with quasi-zero stiffness. It has high vibration control properties at low weight and dimensions. Also the developed vibration isolator with quasi-zero stiffness can protect against lowfrequency vibration. The vibration isolator is of a passive type, made from a single elastic material, which will be compact and convenient in manufacturing. An analytical study of the vibration isolation, its manufacturing and experimental static study are presented. The natural frequency of the developed vibration isolator with quasi-zero stiffness is less than 1 Hz.
This article is devoted to finding solutions of problems of vibration isolators with quasi-zero stiffness from a manufacturing point of view. The following study is appeared after experimental study and manufacturing of preproduction serial of universal isolators of a dome type. An analytical description of some types of vibration isolators with quasi-zero stiffness is briefly observed. The sensitivity of vibration isolators of a dome type is studied. It is proved that vibration isolators with quasi-zero stiffness require high precision at manufacturing. Dynamics of a group of vibration isolators is also analyzed. It appears that an average behavior of an isolator in a group may not coincide with the behavior of a single isolator. Due to the normal distribution of parameter, the total properties of the vibration isolator can be slightly changed.
