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.
