Dirt Late Model Vehicle Dynamics - Part 4

Welcome to the fourth installment in our series on dirt late model vehicle dynamics. In part three, we looked at the development of the first three equations in our dynamic system. We are referring to the first three equations as the “load transfer equations”. In part four, we are going to take a closer look at how engine torque reactions are incorporated into the second and third equations.

Dirt Late Model Vehicle Dynamics - Part 3

Welcome to the third installment of our series on dirt late model vehicle dynamics. In part two, we looked at some of the basic concepts of engineering analysis to use as a procedural baseline. We also discussed the eight unknown values of force and displacement that we will be solving for. With this understanding, we can now begin to look at the equations that will make up the mathematical model defining our race car.

Dirt Late Model Vehicle Dynamics - Part 2

Welcome to the second installment in our series on dirt late model vehicle dynamics. In part 1 of the series, we talked a little about some of the technical resources available on race car vehicle dynamics and the differences between the engineering involved when looking at a pavement race car as compared to dirt track race car. We also talked about the differences between analytical tools used to evaluate a race car,

Dirt Late Model Vehicle Dynamics - Part 1

Welcome to the first installment in a series on dirt late model vehicle dynamics. The purpose of this series is to provide a mathematical explanation to some conceptual ideas well known throughout the dirt racing community. Many people successfully use chassis engineering concepts to tune their race car without understanding the underlying mathematics. This series aims to close that gap and help the reader obtain a better understanding of the science behind what their race car is doing. No need to worry if math was not your strongest subject in

BME Shopping Mall Grand Opening

It has been a few months since the last post. I am excited to say lots of things have happened since then. I made a trip to Indianapolis to attend the PRI show where I had the opportunity to speak with several vendors. We have since started filling the BME shopping mall with circle track racing related items. I was originally going to focus the store on only dirt late model related products, but after speaking with several people at PRI, I have been convinced to expand the scope to include dirt modifieds and dirt street stock related items as well. Bringing

Website Progress

The website is coming along nicely.  We are adding new content daily.  

Our first simulation tool will be coming online soon.  It is a simulation that mimics a "spring smasher".  For those of you who may not know what a "spring smasher" is, it is a tool that is used to compress a shock & spring assembly to test the force generated by the assembly at a given distance.  It is a valuable tuning tool that is often used to set up the suspension of a chassis when the desired ride height force targets are known.  The "spring smasher" lets you set the preload on the shock/spring assembly prior to installing it on the car.  This tool is also commonly
