NASCAR R&D involves various automotive tests to ensure the safety, performance, and aesthetics of the Next Gen race cars. Some of the tests include:
- Crash testing: This involves simulating different types of impacts, such as right-frontal, T-bone, rear, and roof crush, using FEA models and physical prototypes. The goal is to optimize the deformation and energy absorption of the chassis and body, while protecting the driver and the fuel cell123.
- Aerodynamic testing: This involves designing and testing the shape and features of the body to achieve the desired downforce, drag, and lift characteristics. The goal is to balance the handling, speed, and stability of the car, as well as the manufacturer identity and relevance2.
- Wind tunnel testing: This involves measuring the aerodynamic forces and moments on the car in various conditions, such as yaw angle, ride height, and crosswind. The goal is to validate the CFD simulations and optimize the setup of the car for different tracks2.
- Lift-off testing: This involves evaluating the vehicle’s tendency to become airborne in high-speed accidents, and the effectiveness of the roof flaps and other devices to prevent it. The goal is to reduce the risk of injury and damage to the driver, spectators, and other cars2.
