Project description

The subject of the project was a TTMA device (mobile absorber of kinetic energy when a vehicle hits a stationary or slow-moving truck, used on roads in work zones and during maintenance work).

Solution

SolidWorks software was used for the design work. The numerical model of the TTMA was prepared in Altair HyperMesh. The calculations were carried out in LS-Dyna.

The result

A prototype of the TTMA mobile absorber, meeting the requirements of European standard CEN/TS 16786:2018 for an impact speed of 100 km/h (confirmed by experimental tests).
