摘要

This invention relates to vibroengineering and can be used in any field where there are forced oscillations and where there is a need for vibration testing. The main goal of the invention is the realization of complex periodic or chaotic motion of shake-table and hence improvement of vibration testing quality (reliability). Proposed approach is that the transformation of the simple periodic motion into the complex periodic or chaotic oscillations is performed using specially designed non-linear elastic elements 4. The properties of these spring elements are dependent on the design parameters and the desired complex motion parameters (amplitude, spectrum).
