Abstract

For detecting dynamic parameters of apparatus, some specified impact experiments must be carried out on impact testing machines. The various requirements of acceleration peak and impulse duration are demanded for the impact testing machines with different functions. The material properties and geometrical configuration of the striker and target of impact testing machines are important factors for the detected acceleration responses. In the present work, the experiments and numerical simulations are carried out to investigate the influence of the geometrical configuration of the striker and material properties of the target on acceleration curves. The analysis indicates that the acceleration curve greatly depended on the geometrical configuration of the striker and material properties of the target. Analyzing those dynamic response characteristics of impact testing machines is helpful for improving equipment quality. Keywords: impact testing machine, dynamic response, acceleration curve, acceleration peak, impulse duration, geometrical configuration, material properties.
