- •
A method is proposed to calculate the steady state responses of multiple-degree-of-freedom (MDOF) non-linear dynamic systems using incremental nonlinear control parameters.
- •
The proposed method only requires the solution of linear equations.
- •
With the proposed method, the sensitivities of steady state responses with respect to nonlinear control parameters can be calculated simultaneously.
- •
The working of the proposed method is illustrated by a MEMS device subject to electrostatic forces.
