The viscoelastic effect of rubber material on creation of rolling resistance is responsible for 10-33% dissipation of supplied power at the tire/road interaction surface. So, evaluating this kind of loss is very essential in any analysis concerned with energy saving. The transient dynamic analysis for including the rolling effects of the tire requires long CPU time and the obtained results are ...

In this paper, we adopt a matrix treatment to solve the variational problem that consists of determining physical path traveled by light between two points in medium whose refractive index depends on spatial coordinate. The considered begins with trivial repetition expression value functional, expressed form matrix. Next, trick (of Dirac) originally used as part construction dynamic equation re...

A microclimate classification of the entire Bologna Municipality has been carried out in order to give a tool local administration drafting General Urbanistic Plan (PUG). The city was classified considering variation air temperature as function surface characteristics, vegetation fraction, building density and H/W ratio (height width). Starting from analysis with fluid-dynamic modeling (Envi-me...

This two-part paper develops a non-iterative coordinated optimal dispatch framework, i.e., free of iterative information exchange, via the innovation equivalent projection (EP) theory. The EP eliminates internal variables from technical and economic operation constraints subsystem obtains an model with reduced scale, which is key to optimization. In Part II this paper, novel algorithm explicit ...

As the key connecting part of rigid flexible coupling manipulator, structural dynamic characteristics bolted joint are analyzed by using simulation technology pro/e and ANSYS. Based on spring equivalent principle, finite element model bolt is established, relationship equation between contact surface pressure preload derived, its stress state analyzed; micro convex deformation Hertz theory, tan...
