"Using On-Road and Laboratory Testing to Evaluate Fleet Tire Options for Maximum Fuel Efficiency"
Our first webinar in the Smithers Rapra 2015 Webinar Series covers a key topic for many fleets; how do I properly evaluate tire choices to maximize on fuel efficiency. Even with the recent reduction in fuel costs, fuel still makes up one of the highest overall cost categories for vehicle fleets. There are several options for evaluation of tire choices today and each will help to provide information that can aid in making purchasing decisions. This webinar will cover two of the methods that can be used to evaluate multiple tire options for fuel efficiency: road fuel tests and laboratory rolling resistance testing. Dustin Stricker, Maintenance Manager for R.E. West Transportation will start our discussion with a short case study of a recent road fuel test. Road fuel tests give fleets real world data by quantifying fuel efficiency performance while attempting to maintain other constants in the test (i.e. route traveled, driver, truck configuration, etc.). The case study will cover the impetus for the test, how it was administered and the results that were received.
Another technique for evaluating tire options is laboratory based rolling resistance testing. Madhura Rajapakshe, R&D Test Engineer at Smithers Rapra, will discuss an overview of rolling resistance testing and how it measures the values needed to develop conclusions from the data. As part of the full case study involving R.E. West Transportation, Smithers also evaluated the same tire options used in the road fuel test to determine if there was a correlation between real world and laboratory rolling resistance testing. The results of the laboratory test will be shared and the correlation will be reviewed along with examples from other industry studies. In short, the webinar will provide attendees with a useful case study that can be used as a possible model for future fleet tire evaluations.
The webinar will be held on March 18th, 2015 at 11:00 AM EST. Registration is now open. Click here to register online. Attendees will also receive an email with a link to download the presentation materials after the event.
"Insights on Producing a High Fidelity Tire Model"
The second webinar in this series focuses on tire development and engineering for vehicle OEMs, racing teams and other equipment OEMs as we discuss tire modeling - the science that combines data, programming and vehicle knowledge to develop truly useful engineering tools. The equation is complex; how do you develop test methods that produce data that can easily be modeled or programmed to predict actual vehicle performance. The data and programming have improved greatly over the years, and this webinar will be focused on demystifying the complex process.
The modeling process starts with data. What methods will produce the data needed to “fit” into a given tire model? Vehicle models are extremely detailed and require specific data points that will predict how the vehicle will handle under different driving situations. Chassis durability, vehicle handling and ride comfort all depend on axle inputs from the tests. Force and moment testing provides users with much of the data required to calculate the outputs for the model.
But what model should you use? There are three different model types that are commonly used: (1) Finite Element Models, (2) Pacejka Style Models and (3) Component Level Models. This 1 hour webinar will describe in detail a variety of factors to consider when choosing tire models for use in development activities.
- What goes into good tire models (data, testing, considerations)
- How does that data get turned into the models and how do those models get used or integrated with other vehicle models?
- What are the models (pros and cons of each)?
The webinar will be presented by two experts with years of experience in vehicle handling and tire performance. Our presenters include Dean Tener, Technical Manager for Ravenna Laboratory at Smithers Rapra and Mike Stackpole, President of Stackpole Engineering. The webinar will take place on Thursday, April 30th at 11:00 EST.
