[Stress Luminescence Technology - Application Example] Advancement of Automotive Simulations such as Collisions

Stress luminescence technology that glows when force is applied. Here are examples of its application in simulations of impact collisions.

<What is stress photoluminescence?> The core of stress photoluminescence technology is stress photoluminescent particles (ceramics, with a representative material being SrAl2O4:Eu2+, emitting green light). This stress photoluminescent material is applied as a coating or sheet to the area of interest where "force information" is desired. When a load is applied, the resulting stress photoluminescence is captured using a camera, allowing us to see where the force is applied and the extent of the strain that occurs. This is "stress photoluminescence." <Examples of stress photoluminescence applications> *Provided by AIST ■Target: Vehicles ■Development example: Enhancing simulations using stress photoluminescence as training data *For more details, please refer to the PDF document or contact us.
