Abstract:
|
A tape spring hinge is a tape curved along its width, which can be folded to be used
to deploy structural elements in aeronautical applications. Tape springs are both simple
and robust, and they are being increasingly used in designs of actuators to deploy, among
other things, solar arrays in satellites. Due to their simplicity and low weight, traditional
methods to study their behaviour when applying moments can be inconvenient. This
report develops a series of easily accessible algorithms which allow the study of tape
spring hinges through Photogrammetry and Digital Image Correlation calculations when
purely bending the tape spring. By processing and treating images, 3D structures of the
tape spring when bent can be recovered. The steps to carry out the experiment and the
mathematics behind the process completed by the MATLAB algorithms are explained in
this report. |
