...) was used as an optimization algorithm to minimize differences between the standard dynamics and UHS approaches at the position and velocity levels. The robustness of resulting UHS was validated to predict the behaviors of the simple four-bar mechanism and the forestry crane. The focus was on numerical...

...V. P. Premchand; M. D. Narayanan; A. S. Sajith This work presents a new strategy in design optimization of nonlinear vibration absorbers with continuous and discontinuous motions. A cluster-based harmonic balance aided optimization technique using force balance or energy balance as the basis...

...Louis A. DiBerardino, III; Harry Dankowicz 1 Corresponding author. In the discussion below, we begin by collecting results from linear analysis that demonstrate that a globally optimal control strategy may always be found to retain a symmetric response, even as symmetry-breaking changes...

.... The result, regarding the wave propagation speed, agrees well with the reference speed as defined by the UIC code. On the contrary, the pantograph model is unified with the finite element catenary model, and the dynamic interaction of the catenary-pantograph is simulated. An optimization technique to find...
