A deformation history integral (DHI)‐type hysteresis model is an elastic–plastic model that was originally developed for high‐damping rubber bearings (HDRs). The model can show the complex characteristics of HDRs. However, the model cannot accurately consider performance changes due to production variation, temperature dependence, repeated loading dependence, etc. Herein, an improved DHI model that can accurately reflect performance changes is proposed. The main contributions of this study are as follows: (1) To reflect performance change, the DHI model is improved by defining material parameters as a function of the performance change ratios. (2) To accurately reflect repeated loading dependence, including the scragging effect, the DHI model is improved by defining the performance change ratios as a function of the cumulative energy per unit volume. The authors have previously developed a substructure real‐time online testing system. The system performs a time‐history response analysis via analysis and testing systems. To verify the accuracy of the proposed model, a time‐history response analysis is performed using the proposed model, and the results of the substructure real‐time online testing system are compared. The results show that the proposed new hysteresis model can predict the complex behavior of HDRs more accurately than existing analysis models.

Improved deformation history integral type hysteresis model (DHI model) is proposed. Original DHI model was elasto-plastic model and developed mainly for high-damping rubber bearings. While the model can represent the complex behavior of high-damping rubber bearings, there is an issue that the model cannot consider the performance change. Thus, the model was improved by defining the material parameters as a function of performance change ratio. In order to confirm the accuracy of the proposed model, time history analysis was carried out and compared the result of analysis with that of substructure real-time online testing system.
