ABSTRACT:
An impact testing system for determining the shock response of a test structure includes a mass (e.g., a spherical steel ball) and a potential energy storage system (e.g., a spring-loaded mechanism) configured to store mechanical energy and, upon actuation, release the stored mechanical energy in the form of kinetic energy. A hold-and-release mechanism (such as a permanent magnet) is configured to releasably couple the mass to the potential energy storage system and impart linear momentum to the mass in connection with the kinetic energy such that the mass impinges upon the test structure. The shock response can then be determined and displayed to a user.
