Apparatus for determining deformation response

摘要

One aspect of the inventive technology may be generally described as a method for determining test object deformation response that comprises the steps of moving a deformation force deliverer 1 to deliver deformation force 24 to a test object 3; adjusting a deformation force deliverer affecting input so as to meet at least one constraint while performing the step of moving the deformation force deliverer 1; deforming the test object 3 with the deformation force 24; and determining test object response to the deformation force. Corollary apparatus, in addition to other inventive apparatus and method aspects relating variously to test object deformation response determination are part of the inventive technology. Such aspects may relate to the use of a linear actuator 15 in a test object deformation and to identity of motion of a deformation force deliverer 3 and a force deliverer drive component 75, as herein described.

1. An apparatus for determining test object deformation response, comprising:
a force deliverer drive component that moves at a first speed and a first acceleration while delivering a drive force; a deformation force deliverer to which said drive force is delivered and that moves simultaneously with said force deliver drive component at said first speed and said first acceleration to deliver deformation force to a test object; and a test object response determiner that determines a deformation response of said test object to said deformation force, said test object response determiner comprising:
recorded drive component current versus test object deformation calibration data for a plurality of drive forces and said test object; anda computer processor programmed to use said calibration data for said plurality of drive forces to transform measured test object response data into generated test object response data, wherein said generated test object response data comprises test object deformation position versus deformation force data.
