Work by profs keeps trains on right track
By Leslie Hirschbach Staff writer
Two KU professors, with the help of a $50,000 grant this year from an Atchison company are making the announcement that they have since the railroad first went west.
Donald Gyorog, chairman of the mechanical engineering department, and Karan Surana, associate professor of mechanical engineering, who anchors the anchors are angled to better handle the stress from heavy train cargo.
Gyorog said recently that the steel anchors were clipped to the base of the metal rail that guided the train to hold the rail down.
"It works like a big spring or paper clip," he said.
When a train puts on its brakes, he said, the anchors prevent the rails from buckling.
Gyroog said the Unit Rail Anchor Company, which manufactured about 250,000 anchors a year at about 80 cents each, set up the grant to test and improve its anchors. manufacturers induced the company to test and improve its anchors.
Gyorog and Surana have suggested to the company changes in the angles
and bends of the anchors based on simulations set up on their computers. Gvorog said.
Since February, when the professors received the grant, analysis of the anchors has been done on a computer using a model, or picture, of one of the company's anchors, Gyorog said.
"We then apply imagined loads and analyze the effect on the rail anchor," he said.
Gyorog said that the simulations pointed out the weak points and that modifications of the anchors were on the computer to reduce the stress.
Different train loads and speeds produce varying degrees of stress at different points on the anchor. Each anchor acts as a dip as a different color, Gyorog said.
"The color shows you where the intense stresses are," he said.
He and Surana have made reem-
mentations based on their results
and will continue studying the
anthers for about another year, be said
Gyorog said competition from other universities for the grant made receiving it special.
