Abstract
The objective of this project is to do a research on the stress spread value of the Dead
End Clamp (DEC) with a product sized of 70. This product functions at low voltage
electric power transmission process. Finite element method (FEM) which focused on
the Main Body Structure was used as stress analysis tool. The model structure was
designed according to the standard dimension existed in the market. However, this
product did has some problems in its operation in which the cable tend to split out when
operations under high force. This research was conducted to solve this problem so that
the product can withstand higher force without any fail. I-DEAS software was used to
generate the model and then, this model was analyzed to investigate the stress spread
value of the product during operation.
In I-DEAS software, the Main Body Structure model was a solid element type and it has
4667 nodes and 2308 elements which were used for simulation. The product was
simulated to hold the cable at a maximum loading value of 1200 kg. From this
simulation, the relation between the changes of stress spread value and the Big Strip
parameters which situated at Main Body Structure was established. The main advantage
of this project, with those parameters changes, the Dead End Clamp product could
withstand higher loading. Some suggestions for DEC structural design in the future
were elaborated at the end of this report.
