After experimenting with solutions based on farm equipment, he came up with SoftWheel, a high performance wheel that replaced spokes with three compression cylinders, incorporating suspension into the structure of the wheel itself.
In the USA, Robles Hernández et al. [2] developed a high performance wheel steel, called SRI wheel steel, and compared it with seven other high-performance wheels, six pearlitic and one bainitic, manufactured by different companies.
Ideally, this steel will be proposed as high performance wheel steel to the Association of American Railroads AARR).
The methodology followed by Transportation Technology Center, Inc., to develop a pearlitic high performance wheel steel (identified as SRI) is described in the first part of this paper.
Some of these high performance wheel steels had been tested in heavy haul lines, but had not been tested in the USA heavy haul environment.
The cleanliness and mechanical properties of the SRI wheel steels compared to the other high performance wheel steels show that among the pearlitic steels, the SRI steel has the highest cleanliness and mechanical properties.
Today, he offers GEM add-ons like front and rear towing hitches, roof racks and high-performance wheel setups, including burly off-road knobbies or larger-radius wheels with low-profile tires, that can speed a GEM up to 30 or 35 m.p.h.
Researching high-performance wheel materials is important in wheel/rail development in order to reduce the wear between wheel and rail and prolong service life [1].
The driving performance of wheels is analyzed using absolute performance indices such as drawbar pull, driving torque, and wheel sinkage and also using relative indices such as the drawbar pull coefficient, tractive efficiency, and entrance angle.
After Dylan Tichenor winds up his wobbly performance, Anderson wheels around and peers into the dim studio.
