Finite Element Crash Test Simulation

Key crash test scenarios:

  • Frontal Impact: In this type of crash test, a car is propelled into a barrier at a specified speed to assess how well it can protect occupants in the event of a head-on collision. The test measures the deceleration of the car and the impact on the driver and passenger dummies.
  • Side Impact: In this test, a car is hit from the side by a moving barrier to evaluate how well it protects occupants in the event of a T-bone collision. The test measures the impact on the driver and passenger dummies and assesses the car's ability to maintain its structural integrity.
  • Pole Impact: In this test, a car is propelled sideways into a rigid pole to assess its protection against side collisions with narrow objects such as trees and poles.
  • Rear Impact: This test evaluates a car's ability to protect its occupants in a rear-end collision. The test measures the whiplash effect on the driver and passenger dummies.
  • Pedestrian Safety: This test assesses a car's ability to protect pedestrians in the event of a collision. The test measures the impact on a pedestrian dummy's head, legs, and other body parts when struck by the front of a car.
  • Child Safety: This test evaluates the protection provided by car seats for children of different ages in various collision scenarios.
  • Roof Crush Resistance Test: The roof crush resistance test evaluates the ability of a vehicle's roof structure to withstand a rollover crash. The test involves applying a force to the vehicle's roof until it crushes by 5 inches.
  • Rollover: Rollover tests are designed to evaluate the safety of a vehicle during a rollover accident. The test simulates a vehicle rolling over at a set speed. The results are used to determine the amount of force that is transferred to the occupants of the vehicle.

Crash Test Simulation

Here at OLTRION, we use finite element simulation (FEA) for crash test and crashworthiness because it allows us to predict the behavior of the car structure and occupants during a crash without the need for physical testing. FEA enables our engineers to create a computer model of the vehicle and simulate the crash scenario using various materials and structural designs.

By using advanced Finite element solvers such as Ansys LS-Dyna, ESI Pam-Crash and Simulia Abaqus, we can assess the structural integrity and crashworthiness of the vehicle's components, such as the …
