In this study, a methodology is suggested by applying axiomatic designtheory to multi-objective optimization of engineeringdesign problems. In axiomatic design, Semangularity (S) and Reangularity (R) are utilized to decide which design is better. However it is not used for optimization purpose. this proposed methodology is applied on two case studies, as theoretical and thermal system multi-criteria optimization problems. It is foreseen that this methodology will reduce the degree of coupling in design optimization.

A new interior-point algorithm for the computation of shakedown loads has recently been developed by the authors. the analytical formulation is based on the statical shakedown theorem by Melon which leads to a nonlinear convex optimization problem. the algorithm's efficiency results from the close adoption of the solution procedure to the specific problem of shakedown analysis. this paper focuses on algorithmic aspects of the proposed method. A numerical example of practical interest is used for validation purposes.

the paper describes a 2-DOF parallel kinematic machine designed to achieve precise solar tracking. the mechanism has been developed keeping in mind that solar concentration technology requires a precise alignment of photovoltaic modules and sun radiation, with error allowance much lower than those ensured by traditional sun trackers. the paper describes the kinematic structure and discusses its forward and inverse kinematic, providing the tools to design a system that satisfies the requirements for dexterity and workspace.

the nonlocal continuum theories are capable to reflect the small length characteristic of nanostructurcs. In this work, variational principles arc presented for the stability analysis of multi-walled carbon nanotubes under various mechanical loadings based on the nonlocal elastic Donnell's shell by the semi-inverse method. In this manner, a set of proper essential and natural boundary conditions for each layer of the multiwalled nanotube is derived.

the object of the present study is to design a micro switch witch activates the airbag of a car when the amplitude of the acceleration of the accident exceeds the critical one. the response time of the micro switch is supposed to be 5 ms. Micro switch consist of a proof mass connected to a clamped-clamped micro beam. the nonlinear partial integro-differential equation of the motion is solved using FEM. According to the results it is recommended to use micro switches instead of accelerometers as airbag activators in car's safety systems.

this article presents a perturbation approach for the bifurcation analysis of MDoF vibration systems with gyroscopic and circulatory contributions, as they naturally arise from problems involving moving continua and sliding friction. Based on modal data of the underlying linear system, a multiple scales technique is utilized in order to find equations for the nonlinear amplitudes of the critical mode. the presented method is suited for an algorithmic implementation using commercial software and does not involve costly time-integration. As an engineering example, the bifurcation behaviour of a MDoF disk brake model is investigated. Sub- and supercritical Hopf-bifurcations are found and stationary nonlinear amplitudes are presented depending on operating parameters of the brake as well as of tribological parameters of the contact.

In this work, we study a kind of manipulation process during which we deal with active objects. An active object is a concept covering a variety of objects that are not rigid and need to be controlled during the manipulation process. Here, we use a multi-link mechanism with active motors (actuator) as the object and a series of simple planar manipulators to perform the manipulation process. Dynamic, control, motion planning, and stability at the presence of impact are the most important challenges in this work

Sealing systems used fir non-metallic rod pneumatic drives have hard duty conditions, including the absence of any kind of lubricant and non-linear thermal regime. Due to this, the wear evolution of the lip -rod pair can be difficult to be estimated. the paper propose an ANN based method for wear prediction during service life of the hp seals, taking into account some seals' working behavior influencing factors.
