Fast and Safe – University Students Test Their Race Car with ESI Virtual Performance Solution

Virtual Performance

Czech Technical University in Prague
“Using ESI Virtual Performance Solution to investigate the performance of a composite crash absorber completely virtually enabled us to complete the structure’s design efficiently. Within a couple of days, the students learned how to use the software effectively and were capable of carrying out complex chained analyses”.
Michal Vašíček, Project Consultant Czech Technical University in Prague (ČVUT)


When a group of students at the Czech Technical University in Prague (ČVUT) began working on a “Formula Student Vehicle” project, they immediately opted for Carbon Fiber Reinforced Polymer (CFRP) to build the crash absorber so they could “go fast and be safe” on the track. However, they had to abide by a strict timespan for design and manufacturing and stay within a tight budget, allowing no room for error.


In the automotive industry, especially motor sports, crash absorbers made of Carbon Fiber Reinforced Polymer (CFRP) are widely used because they have the best energy dissipation capacity to weight ratio amongst engineering materials. The team at ČVUT knew this well, but they also knew the challenge of designing and manufacturing these structures efficiently. Read full story


The students were able to avoid physical crash tests of their CFRP race car thanks to ESI Virtual Performance Solution (VPS), using only virtual coupon tests of the CFRP material to validate the material model. This enabled them to move swiftly to the design optimization of the crash absorber structure. The capability of VPS to complete multiple simulations on a single core model allowed the team to thoroughly examine various geometries of the absorber at any given time. The End to End solution supported the project goals, which were met entirely within the allotted time and budget
