Abstract
In this study, the authors conducted a detailed simulation of the side collision process for an SUV model using the finite element method (FEM) and Hyperworks simulation software. The specific SUV model used in this simulation was from Nissan, with various boundary conditions incorporated into the model to replicate real-world crash scenarios closely. These boundary conditions included factors such as the road surface, the collision column, the angle of impact, and the interactions between the different parts of the vehicle. For the collision speed, the authors adhered to the National Highway Traffic Safety Administration (NHTSA) standards, choosing a speed of 32km/h, which is typical for side-impact crash testing. The collision was simulated against a fixed column at an angle of 75 degrees to assess the vehicle's response. The simulation results were then evaluated based on the standards set by the Insurance Institute for Highway Safety (IIHS), specifically the guidelines outlined in their April 2024 standards. The evaluation focused on critical aspects such as the penetration of the vehicle's components at the driver's position and at the location where the car door made contact with the collision column. The results indicated that the vehicle's structure demonstrated sufficient durability, with the materials used in its construction providing adequate protection. Moreover, the penetration of various elements did not compromise the safety of the occupants, as the distance between the center of the driver's seat and the impacted door was reduced to 35.57cm, still well above the safety threshold of 18cm. This result confirms that the vehicle design meets the necessary safety standards for side-impact collisions, ensuring the protection of the driver during such an event.
