Golf club maker Cleveland Golf (www.clevelandgolf.com), Huntington Beach, Calif., is beating par on its manufacturing game by using a physical modeling and simulation tool to increase the performance of its drivers.
Cleveland Golf’s engineers used MapleSim software from Maplesoft (www.maplesoft.com) to investigate how driver performance would be affected by various shafts—studying the flexibility of the shaft, and how the bending and torsion varies down the length of the shaft.
They worked with John McPhee, NSERC Industrial Research Chair and professor of systems design engineering at the University of Waterloo (www.uwaterloo.ca) in Canada, to create a model of a driver with MapleSim. They also got help from varsity players on the university’s golf team, taking experimental measurements to simulate a variety of swings.
Cleveland Golf found good to very good agreement between the simulation and the experimental data, and MapleSim models ran significantly faster than similar models based on finite-element techniques. "The MapleSim models we're running allow us to predict head delivery conditions with more variables, higher precision, and faster run times," says John Rae, research manager, R&D, Cleveland Golf. "Using MapleSim's simulation tools we can generate custom swing calculations based on every equipment variable, leaving nothing to speculation."
