abstract: a continuously variable transmission (cvt) is a transmission which may change step less by way of an infinite variety of effective gear ratios between maximum and minimum values. this contrasts with different mechanical transmissions that solely permit just a few different distinct gear ratios to be selected. continuously variable transmissions (cvts) are mechanical devices that allow...
this paper concerns the design and analysis, of a ball type continuously variable transmission, (b-cvt). this b-cvt has a simple kinematic structure, and same as a toroidal cvt, transmits power by friction on the contact points between input and output discs, that are connected to each other by balls. after, a brief introduction of our b-cvt structure, the performance and traction efficiency of...
investigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

fuzzy logic has been developed over the past three decades into a widely applied techinque in classification and control engineering. today fuzzy logic control is one of the most important applications of fuzzy set theory and specially fuzzy logic. there are two general approachs for using of fuzzy control, software and hardware. integrated circuits as a solution for hardware realization are us...
This paper shows a 99 [g] finger joint that can exert a very strong fingertip force of more than 100 [N]. We have proposed a simple and small load-sensitive continuously variable transmission (CVT), which consists of five links and a torsion-coiled spring. The maximum fingertip force of our previous finger was limited by the mechanical strength of its links and bearings, not by the power of its...
the aim of this work is to find an efficient aerodynamic-based design algorithm for projectile fins and configuration shape optimization. three-dimensional supersonic flow over a projectile with fins at much number 5 and one degree angle of attack was studied. the runge-kutta method and multi-block technique was used to solve the governing equations. a basic configuration was assumed for the fi...
the control of the configuration of the nise nanostructural thin films with temperature
In this research, the impact of shoulder width and geometry of gas channel with different structures on proton exchange membrane (PEM) has been investigated using numerical method. 3D, non-isothermal was used with single straight channel geometrywhile maintaining the same boundary conditions and reaction area with addition of humidification for anode and cathode. Our study showed that an ellipt...
nowadays, automakers have invested in new technologies in order to improve the efficiency of their products. giant automakers have taken an important step toward achieving this objective by designing continuously variable transmission systems (cvt) to continuously adapt the power of the engine with the external load according to the optimum efficiency curve of engine and reducing fuel consumpti...
