Many mechanical systems manifest nonlinear behavior under nonstationary random excitations. Neglecting this nonlinearity in the modeling of a dynamic system would result unacceptable results. However, it is challenging to find exact solutions problems. Therefore, equivalent linearization methods are often used seek approximate for kind problem. To overcome limitations existing methods, an ortho...

The paper presents an optimal fuzzy logic control algorithm for vibration mitigation of buildings using magneto-rheological (MR) dampers. MR dampers are semi-active devices and are monitored using external voltage supply. The voltage monitoring of MR damper is accomplished using evolutionary fuzzy system, where the fuzzy system is optimized using evolutionary algorithms (EAs). A micro-genetic a...

In the context of dynamic decoupling problems, engineering dynamics has long held modal analysis as an exemplar. The method allows exact decomposition linear multi-degree-of-freedom (MDOF) systems into single-degree-of-freedom (SDOF) oscillators, thus simplifying complex problems considerably. However, is very much a theory; if applied to nonlinear systems, property (among others) lost. This un...

The paper presents a multifunctional joint sensor with measurement adaptability for biological engineering applications, such as gait analysis, gesture recognition, etc. The adaptability is embodied in both static and dynamic environment measurements, both of body pose and in motion capture. Its multifunctional capabilities lay in its ability of simultaneous measurement of multiple degrees of f...

The solution of the motion equation for a structural system under prescribed loading and prediction induced accelerations, velocities, displacements is special importance in engineering applications. In most cases, however, it impossible to propose an exact analytical solution, as case systems subjected stochastic input motions or forces. This also non-linear systems, where numerical approaches...
