An effective method is proposed to calculate sensitivity of nonlinear forced response levels for bladed discs with friction contact interfaces to variation of parameters of these interfaces, including clearances and interferences. First and second order sensitivity coefficients together with ranges of high fidelity for forced response and the sensitivity coefficients prediction are determined. Numerical investigations of the sensitivity of the multiharmonic steady-state forced response of bladed discs with friction contacts and gaps have been performed showing the capabilities and efficiency of the method proposed
