Strategy for Optimizing an F1 Car’s Performance based on FIA Regulations

Oxford Brookes University-Karan Bopaiah, Stephen Samuel
  • Technical Paper
  • 2020-01-0545
To be published on 2020-04-14 by SAE International in United States
With the introduction of the V6 engines in Formula 1, in 2014, the sport aimed to close the gap between the automotive engine and high-performance motorsport engines in the area of fuel economy. A set of very challenging engineering regulations were introduced by the FIA to restrict the power from the Internal Combustion Engine (ICE), while allowing for more power to be harvested through energy recovery systems. Although progress has been made in developing a highly efficient powertrain, the limit to which this system can be pushed to is still unknown due to a significant gap between the technological choices available and the optimal control strategy used. This study investigated an engine-powertrain model of an F1 car with real world driver data for estimating the vehicle’s full throttle performance. The work used engine and drive-cycle simulation-modeling tools to build a representative car model which complied with the 2019 FIA regulations, in conjunction with real world data to identify the most critical parameter such as the gear shift strategy and the maximum energy recovered, stored and…

A Direct Engineering Approach to Draw Die Binder Development Design

Creative Concepts Company-Edmund A. Herman
  • Technical Paper
  • 2020-01-0952
To be published on 2020-04-14 by SAE International in United States
A method of designing the binder developments of draw dies for sheet metal stampings that integrates the mathematics of formability, kinematics and friction into the design (i.e. synthesis) process is described. The method is in four phases: (1) Forming feasibility of the product design, (2) 3D wireframe design of the addendum, (3) Surfacing of the addendum, and (4) Productionizing the design. The objectives (e.g., splits, wrinkles, spring-back, etc) are converted to strains and displacements that must be imposed at strategic locations and then a 3D wireframe of true arcs is constructed to approximate the product geometry. The forming feasibility is then calculated for each arc of the wireframe outward in sequence from the defined strategic conditions quantifying the force-displacement energy continuum that must be imposed at the edge-of-part. The construction of the wire frame is then continued outward arc-by-arc to create the die addendum shape that will impose the required energy onto the edge-of-part, the length of line required in the wrap surface and the blank size. The design is then surfaced and checked with…

Outsourcing Plasma Treatments for Surface Modification

Aerospace & Defense Technology: February 2020

  • Magazine Article
  • 20AERP02_02
Published 2020-02-01 by SAE International in United States

In manufacturing, plasma treatments are often utilized to solve problems that cannot be resolved other ways. Whether attempting to improve adhesion of dissimilar materials; depositing coatings; cleaning surfaces; applying a protective coating that repels water, for example, or biological fluids; or enhancing surface wettability or functional coating, plasma treatments often add significant value to products.

Use of staircase method to validate a new design of engine pulley

Cummins Brasil LTDA-Tadeus Marchesi, Wagner Trindade
  • Technical Paper
  • 2019-36-0255
Published 2020-01-13 by SAE International in United States
A Cummins internal project demanded the development of a new crankshaft pulley. This new pulley will be mounted in the engine, but before this mounting process, a validation phase must be accomplished with the primary goal of avoiding failures during engine tests and, most of all, during vehicle operation. This article documents part of the work done to validate the new pulley, aiming to deliver a component that meets the specification demanded by the application to be released in the market. It is presented how acceptable unreliability of the pulley was assessed by means of fatigue testing. Several approaches could be used, but following internal standards for this kind of component, the procedure chosen was the staircase fatigue method. After finishing the testing phase and data treatment, the findings indicated that the new crankshaft pulley presented infinite life when subjected to the hub load found in the application with a design margin of 82%. Another validation that was carried out is related to the bolts used in the mounting. The bolted joint measurement and its…
