Abstract :
Current technological developments produce various kinds of innovations and
creations in all things, which goal to facilitate all human activities. There are
various kinds of tools for testing, ranging from tensile testing, compressive testing
and hardness testing. In this case, this research designs and develops miniature
tensile test kits. Our goal is to do tensile testing to find out the yield strength,
elongation, tensile strength and elastic modulus. This tensile test equipment is
designed using a servo motor with 3 AC in put, 105 V, 0.7 A with 100 W out put
and 3000 rad / min motor rotation comparable (477.46 rpm), power transfer using
fan belt. This servo motor is controlled by a servo amplifier that goal is to send a
signal to control the motor speed, motor rotation direction. The servo ampifier is
then connected to a laptop / computer to regulate the amplifier, and describes the
test results in the form of stress and strain graphs that occur in tensile test
specimens. The component of the tensile test equipment analyzed in this study
are; specimen pin, grip and grip holder). The goal is to determine the maximum
stress that occurs so it can be categorized as safe or not used for testing
aluminium (Al) and Copper (Cu) specimens. To find out the component is safe or
not with the help of the Solidworks 2014 software. By analyzing the maximum
von Mises stress that occurs in each component analyzed for use in aluminium
(Al) and Copper (Cu) specimens.
