The output frequency response is fundamentally important in the identification, analysis and design of linear systems in the frequency domain with many applications in control, communications, and vibration studies. This research investigation will extend these results by focusing on the output frequency response function [OFRF] for the Volterra class of nonlinear systems, which has recently been derived by the authors. The new OFRF concept reveals, for the first time, that for a wide class of nonlinear systems there is a simple polynomial relationship between the output spectrum and the time domain model parameters, which define the system nonlinearity. This provides the opportunity to analytically conduct optimal designs of nonlinear damping for both sdof and mdof systems, to determine the range of validity of the results, and to validate the new design technology using a vibration supression rig in the laboratory.

输出频率响应在频域线性系统的识别、分析和设计中至关重要，在控制、通信和振动研究中有许多应用。本研究将通过关注Volterra类非线性系统的输出频响函数（OFRF）来扩展这些结果，该函数最近由作者导出。新的OFRF概念首次揭示了对于一类广泛的非线性系统，输出频谱和时域模型参数之间存在简单的多项式关系，这些参数定义了系统的非线性。这为分析地对sdof和mof系统进行非线性阻尼优化设计提供了机会，以确定结果的有效性范围，并在实验室中使用振动抑制装置验证新的设计技术。
