METHODS AND APPARATUS FOR MEASURING PROPERTIES OF A CANTILEVERED MEMBER

摘要

Methods and apparatus for measuring properties of a cantilevered member according to various aspects of the present technology may utilize a test stand comprising a chuck configured to secure a first end of a test member or shaft such that a second end of the test member is cantilevered outward from the chuck. A loading system may be configured to apply a force to the test member causing the test member to deflect in response to the load. An image capturing system is configured to acquire one or more images of the deflected test member and a data acquisition system may analyze the collected data and images to calculate one or more properties of the test member.

1. A test stand for measuring the physical properties of a member, comprising:
a chuck configured to selectively receive and secure a first end portion of the member such that a second end of the member is cantilevered away from the chuck; a load system configured to apply a predetermined load at a predetermined position along the member to cause a deflection along a length of the member between the first and second ends; an image capture system configured to:
capture a first image of the member prior to the application of the load on the member; andcapture a second image of the member after the application of the load on the member; a data acquisition system communicatively linked to the image capture system, the load system, and the chuck, wherein the data acquisition system is configured to compare the second image against the first image to calculate at least one of a stiffness profile and a straightness score for the member.
