An analysis has been presented pertaining to the use of a convex
bottom tank shape instead of an elliptical, for a road tanker.
Two analyses have been made, concerning the static and the dynamic
relative performance expectations of such tank shape when compared
with the elliptical shape performance.
The outputs of both analyses suggest that the level of average benefit
due to using the proposed shape, is around 10%, with a maximum
benefit observed in the dynamic performance in the case of the
minimum fill level.
Correlation between static and dynamic outputs. Manufacturing.
Systems that assess the driving styles and provide a feedback about the driving style (ECO driving App; Ecological Drive Display on Dashboard). Smoothness of driving, with decelerations and accelerations in a given range. -The issue of safety Vs Eco driving –Keeping the right distance with the vehicle in front.
The interaction of the vehicles with the pavements imply damaging effects on both systems, as a function of the operating conditions and design characteristics of both systems. These effects influence the road pricing as well as the maintenance costs of the vehicles. In this paper, a simulation scheme has been proposed to analyze such interaction in massive way, involving a multivehicle models was the uncoupling of the roll and pitch responses. Results suggest that the damaging effects on the pavement and the vehicle, depends on the position along the road profile. However, the vertical design of the road would mainly affect the pavement damage, while the turning maneuvers would strongly influence the damage of the vehicle. Many uses can be identified for the proposed simulation scheme, involving different design and operating conditions for both systems.
The proposed mechanism is based on a cam design and is independent of any external energy source.
Conclusions
Issue 1: An accelerated wear tip of the cam shaped journal .
Issue 2: The spherical rollers proposed for the bearings would be underused, as the contact force will be downwards, and such bearing has supporting capacity in both vertical directions.
Comparative simulations of rail and road infrastructure with the transportation of liquid cargoes
(2018)
A simulation approach has been presented to analyze the lateral stability and infrastructure damage potentials of rail and road transportation of liquid cargoes. The normalized and comparative performance of both modes of transport, reveals that the railway transportation is, comparatively, more aggressive with the infrastructure, and less safe.
