Abstract

Background For the purpose of creating of universal and effective vibroisolators it is necessary to provide the low stiffness on the given forces. Aims and Objectives The purpose is to project the low-stiffness vibroisolation devices to protect the oil and gas transport facilities against the dynamic forces effectively. Theoretical investigation of experimental model and a plan of experimental researches are required. Methods Theoretical investigation and computer modeling with the help of ANSYS are used. Results The project, computer model and the plan of the experiment of the vibroisolator are presented. Conclusion The system with quasi-zero stiffness prospectively is the universal and effective vibroisolator. Low stiffness permits the existence of a very small natural frequency value (1 Hz or less). These vibroisolators can be used to protect equipment from a very low speed shaft, for example, piston-like gas compressor units 10ГКН with shaft speed of 300 rpm, i.e. 6 Hz. Also, quasi-zero stiffness systems.
