Use of Bézier curves in the design of the displacement law of the cam-follower mechanism: Von Mises effective StressUso de las curvas de Bezier en el diseño de la ley de desplazamiento del mecanismo de leva - seguidor: esfuerzo efectivo de Von Mises
(Revista UIS Ingenierías, 2020-07-01)
Designing cams by Bézier Curves has become increasingly common, since the mathematical development of this
method is less complex. Bezier curves are Bernstein-based polynomials under a unitary domain, and in that sense, ...
Influence of the firing process on water absorption and compressive strength in ceramic samples
(Journal of Physics: Conference Series, 2019-11-19)
It is presents the evaluation of water absorption and compressive and flexural strength in perforated blocks manufactured in a Hoffman-type kiln of brickworks Ocaña, Colombia. Combustion gases are reused in the firing ...
Principal stresses on the contact surface of a cam-tracker mechanism designed using Bézier curves
(Contemporary Engineering Sciences, 2018-11-29)
The study exposes the variation of the main stresses in a cam mechanism with
roller follower whose profile has been designed by means of Bézier curves. The
contact theory for the cam case is proposed and the distribution ...
Thermoeconomic modelling and parametric study of a simple ORC for the recovery of waste heat in a 2 MW gas engine under different working fluids
(Applied Sciences, 2019-10-25)
This paper presents a thermo-economic analysis of a simple organic Rankine cycle (SORC) as a waste heat recovery (WHR) systems of a 2 MW stationary gas engine evaluating different working fluids. Initially, a systematic ...
The architecture on land and its construction techniques, millenary tradition that is reborn
(Contemporary Engineering Sciences, 2018-08-30)
In the context of sustainable development, the use of materials of low
environmental impact in the activities inherent to the construction of houses plays
an important role when it comes to reducing waste pollution. The ...
A Semi-Physical Modeling of the Combustion Chamber and Inlet Manifold of a 2 MW Natural Gas Generation Engine
(International Review on Modelling and Simulations, 2020-02)
This article presents a sensitivity analysis based on a validated model of average value in natural gas generation engines under the phenomenologically based semi-physical modeling methodology, which includes both the ...
Study of the fire decomposition behavior of recycled polyethylene terephthalate (RPET) with the addition of MCA additive retardant
(Journal of Physics: Conference Series, 2018-12-07)
Polyethylene terephthalate (PET) currently occupies an important space in the manufacture of bottles for carbonated beverages and mineral water, however, its use has become another pollution problem in the world, due to ...
A comparative study of the cutting parameter in milling process under different material
(Contemporary Engineering Sciences, 2018-06-18)
In the present study, the incidence of the variation in feed rate per tooth and depth
of cut for SAE 4340 alloy steel and SAE J431 steel castings was analysed and in
which material this variation is most noticeable. For ...
Study of the emissions in the diesel engines: A review
(Contemporary Engineering Sciences, 2018-09-12)
Diesel engines are one of the main sources to supply the rapid growth of energy
consumption worldwide. They have been widely used in the public and commercial
transport sector due to their greater durability and efficiency. ...
Ergonomic assessment of the work place of the footwear assembly line. Case: city of Cúcuta - Colombia
(Contemporary Engineering Sciences, 2018-08-20)
A quantitative diagnosis of the ergonomic valuation is presented for people who
work as fitters in the footwear sector due to the use of chairs that are not related to
the users' anthropometric measurements. ...
