The actual assembly is very straight forward and intuitive, but you can use the gallery for reference photos. One note is the upper loading platen and the platen spacer have 4-40 tapped holes to join the two parts together with a .25” piece of 4-40 threaded rod coated in loctite or some epoxy. You can get this threaded rod by just cutting a section of a 4-40 screw off. text/html 2012-10-11T20:24:12-04:00 http://dap.cooper.edu/doku.php?id=start:projects:mechanical_loaderdale:mechanicaltester:gallery&rev=1350001452&do=diff text/html 2012-10-11T20:05:06-04:00 http://dap.cooper.edu/doku.php?id=start:projects:mechanical_loaderdale:mechanicaltester:narrative&rev=1350000306&do=diff Biomomentum's MACH-1 Micromechanical Testing System is an off the shelf solution for evaluating the mechanical properties of biomaterials. However its hefty price tag and relative simplicity make it a target for homebuilt duplication by labs like Colombia's Biomedical Engineering Lab. Constructing a mechanical tester requires the marriage of a load cell to track the force applied, a linear variable differential transformer (LVDT) to track position, and a linear actuator to manipulate the sampl… text/html 2012-10-11T20:05:44-04:00 http://dap.cooper.edu/doku.php?id=start:projects:mechanical_loaderdale:mechanicaltester:use&rev=1350000344&do=diff * Open the program either from source or from the .exe * Go to file->settings and open the default settings, settings.cfg * Go to file->find DAQ and then use the find DAQ button to search for connected DAQs. Then click on Connect to DAQ to initialize the DAQ. Position and load should now display in the software. * Jog the motor all the way to the bottom and verify the bottom limit switch is functioning. Press lightly on the load cell to verify a warning for maximum load reached appears…
