Törmäystestien

Törmäystestit, known in English as crash tests, are a crucial part of vehicle safety development and evaluation. These tests involve deliberately colliding vehicles, either with each other or with deformable barriers, under controlled conditions. The primary purpose of these tests is to assess the structural integrity of the vehicle and the effectiveness of its safety systems, such as seatbelts, airbags, and crumple zones, in protecting occupants during a collision.

The data collected from crash tests is extensive. Accelerometers, high-speed cameras, and anthropomorphic test dummies, often referred to as crash test dummies, are used to measure the forces experienced by different parts of the vehicle and by simulated occupants. These measurements help engineers understand how the vehicle deforms and absorbs energy during impact, and how well it shields occupants from injury-causing forces.

Safety organizations worldwide conduct and publish the results of these tests to inform consumers about vehicle safety ratings. Independent organizations like Euro NCAP (European New Car Assessment Programme) and the IIHS (Insurance Institute for Highway Safety) in the United States are prominent in this field, providing standardized ratings that influence purchasing decisions. The findings from crash tests also drive continuous improvement in automotive safety standards and regulations. By simulating real-world accident scenarios, crash tests play a vital role in making vehicles safer for everyone on the road.
