RISSensitivity of Lyapunov Exponents in Design Optimization of Nonlinear Dampers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work presents how the analytical sensitivity of Lyapunov characteristic exponents (LCEs) can be used in the design of nonlinear dampers, which are frequently utilized to stabilize the response of mechanical systems. ...
Stability Analysis of Nonlinear Rotating Systems Using Lyapunov Characteristic Exponents Estimated From Multibody Dynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The use of Lyapunov characteristic exponents to assess the stability of nonlinear, time-dependent mechanical systems is discussed. Specific attention is dedicated to methods capable of estimating the largest exponent without ...
