Abstract:The Paper is devoted to vibration isolating matematerial. The internal structure is made of a special shape that provide quasi-zero stiffness. Computer modeling was made and parameters providing quasi-zero stiffness have been obtained. Structure with quasi-zero stiffness was analyzed and optimal load was considered. The matematerial has very promising parameters for vibration isolation.

Complex condition monitoring for industrial equipment is offered in this paper. The complex monitoring consists of three parts. The first part contains careful diagnostics of defects. It was greatly improved by using a new method of identification of excitation sources. This method is based on defect location with the help of remote strain gauge control and detects the exact coordinates of the detected defects. The second part covers vibration isolation of industrial equipment. For this purpose, metamaterials with quasi-zero stiffness are offered. They can almost totally isolate dynamic forces passing through them. The third part is dedicated to decrease oscillations of the equipment via dynamic absorbers. Their application can be improved by careful control of adjustment. It is offered to control the phase of oscillations on two ends of the spring.
