Liquid-Spring Shock Isolator Modeling.

Abstract

The purpose of this pilot study was to determine whether mathematical models of high-performance shock isolators could be established from test performance data. A liquid spring was modeled using an open-parameter differential equation. A system identification technique was used to select the best algebraic form of the model and to optimize the parameters for the sample isolator. A comparison of the calculated response variables with the test data showed that the model was accurate and that isolator models could generally be established in this manner. The use of the isolator mathematical model and determination of optimum constant parameters for practical design purposes is discussed. However, conversion of this information to actual hardware design dimensions warrants further research and is not addressed. (Author)
