Doing research, reverse engineering, setting design targets. Additional insight for teams thinking about making the EV transition.
Overall Vehicle Priorities
To manage priorities, ask four questions about every design decision, in this order: 1. Is it legal or illegal? 2. How does the change affect reliability or repeatability? 3. How does the change affect overall vehicle performance over a lap? 4. What are the drivability effects?
Dynamic Valve Event Optimization
The approach to understand what makes an engine run well is to look at the opening and closing of each valve. But whatever you want the valves to do, they’re actually doing something else, because you always have: Deflection, Inertia, and Vibration.
Adding Aero, Justifying Aero
Simply finding the combination that gives the fastest laptime is missing the point. The point is to understand the size of each effect, and how to engineer each effect to achieve the fastest laptime.
Coarse-To-Fine Design
As you move through the design process, you start with insight, then gradually trade insight for accuracy.
Four Ways To Use Data
Defining requirements, validating models, on-car tuning, and understanding the root cause of problems. The process of developing and troubleshooting a steering system.
Tractive Force Graphs
This is a logic path for understanding the performance of your car in straight line acceleration. Understand the impact of gearing and power and torque curves.
Critical Specifications For Balance
Chassis, mass, and aerodynamic interactions affecting steady-state balance, and the purpose of anti-roll bars.
