What Order Do Components Break? Applying Factors of Safety and Peak Loading Using OptimumKinematics Forces Module
As with any aspect of vehicle analysis, simulation is a multi-faceted tool that is only as good as the user can make it function. In addition to performing simulations that looks at how to achieve peak vehicle performance, a significant amount of effort needs to be...
Optimum Kinematics Forces Module – Track Replay
While there are plenty of methods that can be used to calculate the worst-case scenario for a vehicle’s suspension, there is no better way to know than from track data. Rather than estimating the performance envelope of a vehicle by considering the maximum forces that...
Considering Compliance: Using the OptimumKinematics Forces Module to Determine the True Toe Gain
The Forces Module in OptimumKinematics is one feature that can not only benefit the performance of the car through optimization of component design, but also optimization of vehicle setup. Using OptimumKinematics Forces Module the user can use the Multiple Iteration...
OptimumG Announces New Software Pricing
OptimumG announced this week their move towards a subscription based software licensing on all of their software solutions including OptimumKinematics, OptimumTire and OptimumDynamics. This move was done in order to stay true to their company’s mission. OptimumG’s...
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...
