Vibratools Suite - Open Platforms

Overview
NonlinTools™ is a bleeding-edge software platform for simulating and identifying nonlinear mechanical systems. With NonlinTools™ you can simulate time responses, or frequency responses for arbitrary input forces on a multitude of nonlinear systems. The software builds on our unique, breakthrough technology for computing forced response for linear systems in the time domain. In NonlinTools™, this technology has been extended to multiple-degree-of-freedom nonlinear systems with arbitrary force inputs.

Key Features
• Simulation of forced response of linear SDOF and MDOF systems with M, C, K; or M, K, and modal damping; or residues and poles.

• Simulation of forced response of nonlinear SDOF and MDOF systems with M, C, K; or M, K, and modal damping; or residues and poles. Many different implementations.
• Harmonic balance computation from any time signals, experimental or simulated.
• Generation of test signals with sine sweeps, pure random and burst random, for simulation with the routines for forced response computation.
• MIMO estimation of nonlinear multiple-input models according to Julius Bendat.The toolbox for simulating and identifying nonlinear mechanical systems.
