Nonsmooth Modeling of Vibro-Impacting Euler-Bernoulli Beam
Vyasarayani, Chandrika Prakash; Sandhu, Sukhpreet Singh; McPhee, John (Hindawi, 2012-06-17)A new technique to simulate nonsmooth motions occurring in vibro-impacting continuous systems is proposed. Sticking motions that are encountered during vibro-impact simulation are imposed exactly using a Lagrange multiplier, ... -
Parameter identification in dynamic systems using the homotopy optimization approach
Uchida, Thomas Kenji; Vyasarayani, Chandrika Prakash; McPhee, John; Carvalho, Ashwin (Springer, 2011-12)Identifying the parameters in a mathematical model governed by a system of ordinary differential equations is considered in this work. It is assumed that only partial state measurement is available from experiments, and ... -
Single-shooting homotopy method for parameter identification in dynamical systems
Vyasarayani, Chandrika Prakash; Uchida, Thomas; McPhee, John (American Physical Society, 2012-03-02)An algorithm for identifying parameters in dynamical systems is developed in this work using homotopy transformations and the single-shooting method. The equations governing the dynamics of the mathematical model are ... -
Transient Dynamics of Continuous Systems with Impact and Friction, with Applications to Musical Instruments
Vyasarayani, Chandrika Prakash (University of Waterloo, 2009-09-24)The objective of this work is to develop mathematical simulation models for predicting the transient behaviour of strings and beams subjected to impacts. The developed models are applied to study the dynamics of the ...
