-
Used to evaluate vehicles pedestrian protection;
- Compliances with UN R127 and GB24550;
- Including Skin, Flesh, Femur, Tibia, and Knee Assembly;
- Including Femur and Tibia Bending Moment and Knee Displacements;
- Including Data Acquisition Devices and Software.
The lower leg impactor Flex-PLI is used for the development and evaluation of vehicle pedestrian protection performance. It mainly includes the response of thigh bending moment (upper, middle, lower), knee ligament stretch (MCL, ACL, PCL, LCL) and calf bending moment (upper, middle upper, middle lower, lower), and can be measured through the corresponding Sensors and data acquisition units collect and record data.
