Abstract
The presence of bolted joints has a substantial impact on the dynamic properties of the assembly, which is primarily due to slippage occurring in the contact patches. Thus, for reasonable blind predictions, detailed modeling of the contact interfaces is indispensable to capture the nonlinear frictional behavior. However, the drastic increase of degrees of freedom and contact elements leads to a tremendous deceleration of the computational time. To ease the computational bottlenecks, we employ the Proper orthogonal decomposition and the Energy-conserving sampling and weighting algorithm. We demonstrate the feasibility and accuracy of this approach at the Brake-Reuss beam, which allows the determination of the amplitude-dependent resonance frequencies and energy dissipation by time integration. An extensive study on the reusability of proper orthogonal modes is conducted to reduce the offline time in future applications to a bare minimum.
