摘　　要：研究了2自由度含有粘性阻尼双线性滞迟恢复力振动系统简谐激励下的响应计算问题，将等效线性化计算方法推广至含有滞迟环节的多自由度非线性振动系统，并证明了在首次近似意义上，等效线性化方法与Krybov-Bogoliubov慢变参数法、Fourier级数展开法是等价的，具有相同的计算精度。The response computation problem of a two degree of freedom bilinear hysteretic vibration system with viscous damping under sinusoidal excitation is studied. And the equivalent linearization approximate method is extended to a two-degree-of-freedom vibration system having hysteretic restoring force component,the equality in computation precision of equivalent linearization approximate method,K-B method and Fourier series expanding method in fist order approximation meaning is also proved.
