Curious About How We Test Our Skirts?

Transtex prides itself on providing you with the number one aerodynamic skirt on the market. Our products go through rigorous testing to ensure that you get nothing but the best.


Aerodynamic skirts are placed on a shaker rig, which imitates their setup on a trailer. They are then subjected to 70 consecutive hours under a random vibration load, at ASTM D4728 Assurance Level 1, in order to replicate vibrations caused by road conditions. The purpose of this test is to do a life assessment of the skirt in a realistic and controlled environment.


The aerodynamic skirt is subjected to deformation in order to determine how it reacts to body and ground interference, like accidents for example. Destructive testing allows us to observe any failure or damage to the brackets and skirt combination. When combined with computer simulations, the data gathered helps us determine possible failure locations across the skirt and brackets.


A flexural test is performed under various conditions, such as hot and cold temperatures. The purpose of this test is to determine the forces and deflections beyond elastic deformation. Note that elastic deformation is a temporary shape change that reverses once force is removed. Our Blue Bracket, for example, is designed to stay within the elastic region. Furthermore, our kits are also tested for stability on the road in order to measure the displacement amplitude of the side skirt assembly under road vibrations.
