Suspension kinematics and its effect on performance
To make a car go faster around a track, there are a couple of things we can do that generally will improve lap times. We can, lower weight, increase engine power, increase downforce, reduce drag, increase tire grip. Unfortunately all these changes typically come with...
Throttle maps and tire wear
In our recent article on the need of power in Formula SAE, we briefly looked at the throttle response of a specific engine. Mapping throttle pedal position to engine torque is a powerful tool for many vehicle dynamics engineers. This mapping can be done mechanically...
It is all about horsepower… or is it?
A vehicle’s performance can be described using many different metrics. The most commonly used is probably engine power. Whether your unit of choice is horsepower, kilowatts or calories per hour, the peak power of an engine is a number most people can relate to. It’s...
Asymmetric Tire Data and OptimumTire
One issue our customers come across every now and then is an asymmetric tire data set. The data set itself is not really the issue, but it can complicate the process of fitting tire models using OptimumTire. An asymmetric tire data set; is tire data collected on a...
Linear or non-linear – that is the question!
Among all the topics discussed during the Vehicle Dynamics and Control Seminar hosted in Cambridge last year, there was one issue the delegates seemed unable to agree upon. The handling limits of virtually all road vehicles are dictated by the tires, how much force...
Has video killed data acquisition?
Video killed the radio star is the title of The Buggles’ hit from 1979, their response to the upswing of music videos. In recent years video based data acquisition systems have become increasingly popular among weekend racers and smaller race teams. Has video killed...
Torsional stiffness
There are many words and expressions commonly used in vehicle dynamics, many of these are very abstract and hard to visualize. One of these words is torsional stiffness. The torsional stiffness of chassis is relevant to help understand how roll stiffness torques from...
About our Technical Articles
There are tons of interesting blogs to read, some of them are about politics or fashion. There are even some on bread. The one topic we at OptimumG haven’t found being properly covered anywhere is vehicle dynamics. With our technical articles, we want to create a blog...
