Battery electric vehicles (BEVs) represent a possible sustainable solution for personal urban transportation. Presently, the most limiting characteristic of BEVs is their short range, mainly because battery technology limitations. A proper design and control drivetrain, aimed at reducing power losses thus increasing BEV can contribute to make electrification transportation convenient choice. This paper presents simulation-based comparison energy efficiency performance six drivetrain...
Integrated Chassis Control (ICC) is one of the most appealing subjects for vehicle dynamics specialists and researchers, due to increasing number chassis actuators modern human-driven automated cars. ICC ensures that potential available systematically exploited, by overcoming individual limitations, solving conflicts redundancies, which results into enhanced performance, ride comfort safety. This paper a literature review on ICC, focuses topics are left uncovered recent surveys subject, or...
We present a theoretical approach to estimate the fluid leakage in flat seals. The is based on analogy between seal-substrate interface and porous medium. assume that constituted of random distribution noncontact patches (the pores) small but numerous contact spots (islands). Leakage may occur only through pores, which lateral size height are distributed according probability density function we calculate basis recent theory mechanics. Our percolation scheme has never been proposed before...
This article deals with the dynamic properties of individual wheel electric powertrains for fully vehicles, characterised by an in-board location motor and transmission, connected to through half-shafts. Such a layout is applicable vehicles significant power torque requirements where adoption in-wheel not feasible because packaging constraints. However, performance powertrains, especially if adopted anti-lock braking or traction control, can be affected torsional dynamics presents analysis...
We investigate the effect of statistical properties surface roughness on its superhydrophobicity. In particular, we focus liquid–solid interfacial structure and dependence coupled drop pressure. find that, for self-affine fractal surfaces with Hurst exponent H > 0.5, transition to Wenzel state first involves short wavelengths and, then, gradually moves larger scales. However, as pressure is increased, at a certain point loading history, an abrupt occurs. This sudden identifies critical pW,...
Electric vehicles (EVs) are characterized by a significant variety of possible powertrain configurations, ranging from one to four electric machines, which can have an on-board or in-wheel layout. Multiple models production EVs recently been introduced on the market, with 4-wheel-drive (4WD) architectures based central motor within each axle, connected wheels through gearbox, differential, and half-shafts. In parallel, important body research industrial demonstrations covered topic 2-speed...
We present a simple analytical model and an exact numerical study which explain the role of roughness on different length scales for fluid contact angle rough solid surfaces. show that there is no relation between distribution surface slopes angle. In particular, surfaces with same may exhibit very angles depending range length-scales over have roughness.
A superhydrophobic behavior can be obtained by properly modifying the surface topography of Teflon or other fluorinated polymers having an inherent hydrophobic character. According to this strategy, we have micro/nanotextured both as plane material (sheets) and three-dimensional (3D) object (spheres) with a single step plasma process. The textured samples were compared those made pristine in air, terms repulsion impacting water droplets, underwater, air layer under static dynamic conditions....
Recent applications of continuously variable transmissions with large ratio spread, such as mechanical Kinetic Energy Recovery Systems or recent hybrid architectures, need the transmission to be perfectly reversible. This short paper deals efficiency power-split particular emphasis on switching from forward reverse power flow. Forward and are calculated compared, conditions which make it impossible switch mode studied. In particular, is suggested that, although less efficient at high ratios,...
The Kinetic Energy Recovery Systems (KERS) are being considered as promising short-range solution to improve the fuel economy of road vehicles. key element a mechanical hybrid is Continuously Variable Unit (CVU), which used drive power from flywheel wheels and vice versa by varying speed ratio. performance KERS very much affected efficiency CVU in both direct reverse operation, ratio spread. However, real Transmissions (CVT), spread limited (typical value 6) keep acceptable minimize wear....
In the present context of global economic crisis and environmental emergency, transport science is asked to find innovative solutions turn traditional vehicles into fuel-saving eco-friendly devices. last few years, hybrid have been shown potential benefits in this sense. paper, fuel economy series hybrid-electric hybrid-mechanical buses simulated two real driving situations: cold hot weather city Taranto, Southern Italy. The numerical analysis carried out by an inverse dynamic approach,...
In car–trailer combinations, the hitch angle is relative yaw between towing car and trailer. The literature has shown that inclusion of measurement for feedback control trailer oscillations can bring safety benefits, compared with conventional sway mitigation algorithms based on rate car. Given nonlinearity vehicle system in typical conditions requiring function intervention, nonlinear model-based controllers could be an effective solution. This paper presents four real-time implementable...
