ROADMASTER was the first towing products manufacturer to use computerized testing as well as “real world” physical testing to ensure structural integrity, longevity, and the safety of your family. ROADMASTER’s computerized testing method is called “FEA,” which stands for “Finite Element Analysis.” If that sounds complicated, that’s because it is FEA is the same method NASA scientists use to test their new designs. The automotive, architectural and biomedical industries, among others, also use finite elemental analysis. Every FEA design is displayed as a full-scale, three-dimensional object, which engineers can rotate and study on the screen as they apply thousands of pounds of force across the load-bearing components. Stress in the steel is pinpointed, and the design is manipulated to remove it. The result is an optimized design, in both materials and components, which has been tested and verified at maximum linear strain.
