ANALISA TEGANGAN VON MISES PADA ALAT BANTU JALAN (WALKER)
Abstract: Movement for a walk
is a function that needs to be helped, especially for the elderly because they
experienced degradation of function or sick, one of them is degradation of the
body's energy balance. Not uncommon among those who have trouble for walking,
that is because the degradation on muscle strength in the limbs, for example,
arm muscles, hand muscles, limb muscles, and leg muscles. Moreover, if the
condition is accompanied by degenerative diseases such as osteoporosis,
Parkinson's, stroke, knee pain, and fractures. A walker, making the right
solution. One of the tools is Walker. Walker is an assistant to a very
lightweight, portable, high waist, is made of metal pipe, and this tool comes
with two handles that serves as a place that used to hold users and is equipped
with four sturdy legs as the pedestal.
While the power of the framework are analyzed with the help of CATIA
V5R14 software is to determine the stress that occurs in order to operate as a
walker. It appears that the greatest stress occurs is still under tension
permission of the material itself. Stress equivalent (Von-Mises stress) that
occurs should not exceed 1.583333e+007 N/m2while the voltage that occurs on the
order of 1.77e +005 N/m2 walker located at the foot of the minimum voltage
while working on the framework of the 6.98e-009 N/m2 located on the frame.
