  2. 1. Identification and Simulation Methods for Nonlinear Mechanical Systems Subjected to Stochastic Excitation

    Author : Andreas Josefsson; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinear structural dynamics; system identification; simulation; non-deterministic excitation; zero-memory nonlinear systems; wave power engineering;

    Abstract : With an ongoing desire to improve product performance, in combination with the continuously growing complexity of engineering structures, there is a need for well-tested and reliable engineering tools that can aid the decision making and facilitate an efficient and effective product development. The technical assessment of the dynamic characteristics of mechanical systems often relies on linear analysis techniques which are well developed and generally accepted. READ MORE
