Simulasi Komputer pada Optimasi Desain Hybrid Plating dalam Proses Bone Healing

Abstract

Hybrid plating method that combine locking screw and non-locking screw usually used for healing on bone fracture. This methodusedin order to get the smallestdeflectionandpreventpullout. The research purposed to obtain the optimal parameter design locking screw, such as position of locking screw, thickness and width plates by using Taguchi method which obtained level and variations factor. The material used in this study for screw and the plate were stainless steel SS 316 L. The load model used axial load of 1000 N. The number of hole plates were 8, which 4 holes in each section. In one section consist of locking screw and non locking screw Quasi experimental model applied ANSYS Workbench 14.5 finite element software. Results showed the optimum design was 3 locking scews in the left position, the thickness 4 mm and a width of plate 16 mm. The optimum design produce 0,039507 mm of average deflection and it can be denoted that failure and pull out was not occurred.
