ANALISA TEGANGAN-REGANGAN PRODUK TONGKAT LANSIA DENGAN MENGGUNAKAN METODE ELEMEN HINGGA
Abstract: In any design done
must consider the strength of the staff. The strength that must be considered
regarding the dimensions, materials, and stick structure. In the previous
elderly rod product design, structural analysis found that by just using the
help of software, so that the power structure of the stick product has not yet
been fully elderly a top priority. This is because the previous data was found
that the maximum load that can be received by elderly stick it is 45 N. It
appears that the greatest stress occurs is still under the stress of the
material itself permits. The voltage that occurs on the order of 6.47e +006
N/m2 located on the handle of the stick while the minimum stress acting on the
order of 1.29e-008 N/m2 pipe located at the upper stalk. So the calculation
needs to be done manually to review the results of previous calculations, in
order to improve and enhance the strength of the product stick elderly. Finite
element method is a numerical method used to solve technical problems and a
symptom phisis metematis of which include stress, strain, strength, and
vibration analysis. This finite element method to compare between the
calculations using CATIA software and using the calculations manually. In this
case the finite element method to be used is a 2D finite element method (field)
is a triangular element with 3 nodes. Using Finite Element Method, the biggest
stress on the element 5 with a large voltage of σx = 2.505 x 104, and the
biggest strain on the element 3 with a large strain εx = 0.272. And failure
obtained Theory states: Maximum Normal-Stress Theory declared safe. Because it
is still within safe limits. Maximum Shear-Stress Theory declared unsafe.
