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...
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...
OptimumKinematics aids users in the design and setup of their suspension in an intuitive and straightforward manner, providing useful analysis tools with a user-friendly visual interface. OptimumKinematics is the easiest way for engineers to understand and maximize...
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 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...
OptimumG’s Claude Rouelle explains why, and where, you might want to make use of an asymmetric set-up on your racecar. Having difficulties convincing someone to use more camber on the right-hand side than on the left for a counter-clockwise circuit; running higher tyre pressure on one side than the other; using different damper settings?
Building a Formula Student car? Then you need to read OptimumG engineer Claude Rouelle’s 101 top tips for teams chasing FS glory. In Part 1 of this new mini-series he runs through his first 25 points.
Claude Rouelle explores the possibilities of qualifying and quantifying a racecar design or set-up through grip, balance, control and stability. In the racing industry, I often find engineers that perform simulations in the same way barmen create cocktails: by (sometimes randomly) mixing ingredients and varying quantities until they eventually find something that matches their taste.
Our analysis of yaw versus lateral acceleration continues with Claude Rouelle’s explanation of the yaw moment diagram and how to interpret it. We will start this article by reviewing some basic concepts. As we have seen in the previous articles on the yaw moment versus lateral acceleration method, an understeering car is defined as a car that doesn’t have enough yaw moment and an oversteering car is a car with too much yaw moment.
What makes a car quick in steady state and in transient? Claude Rouelle develops his analysis of lateral acceleration and yaw moment variation. In April’s RE (V27N4), we saw that there are 12 causes for the yaw moment: four tyre lateral forces Fy, four tyre longitudinal forces Fx; and four tyre self-alignment moments Mz.
