The calculation problem of simple harmonic excitation response of dry friction vibration system with single degree of freedom sliding friction coefficient changing with relative velocity is studied. The equivalent linearization method is proposed and the corresponding frequency response equation is deduced. Through a numerical example analysis, we investigate the calculation error when simplified to the ideal dry friction model
