Abstract

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.
