Abstract
The dynamic stiffness and impact stiffness of isolators are the core technical indicators for the performance evaluation of isolators. Accurate assessment is necessary to meet the needs of different usage environments. The main methods for testing dynamic stiffness include the ellipse method, vibration excitation method, and self-excited oscillation method. The main techniques for testing impact stiffness are the drop method and the drop hammer method. Choosing the appropriate testing method based on the characteristics of the test piece can greatly improve efficiency. This paper employs the vibration excitation method to conduct dynamic stiffness simulation and experimental analysis on the spring oscillator isolator model, and uses the drop method for impact stiffness simulation and experimental analysis of the same model. Based on a comparison of simulation analysis and experimental analysis, the effectiveness of the tests was clarified. Moreover, the advantages and disadvantages of various testing methods for dynamic and impact stiffness were sorted out based on the relevant experimental data, to serve as a reference for related testing technicians.
