ABSTRACT
Over the years a series of models and model parameter identification approaches have been employed to produce simulations of normal impact of golf balls against barriers. Models based on experiments at one approach speed have not been very successful when applied at other speeds. An old technique has been revived that uses measured contact times and coefficients of restitution at two speeds to estimate parameters that will permit the Lieberman-Johnson five-parameter model to accurately simulate impacts over a range of approach speeds.
This paper describes the development of an experimental setup and data-reduction procedure to obtain the required contact times and coefficients of restitution. An example of the performance of the resulting model is included.
