Abstract

Finite element method (FEM) has been used to calculate stress analysis in many field of engineering or industry (metal, automotive, power plant and etc.). FEM can be applied to reduce cost of product processing before manufacturing process. Requirement of design of product is cheaper, good properties, effective and efficient depend on function of product. Stress analysis depend on the properties of material, load, static and dynamic and shape of product or component. In the metal processing, FEM is applied for stress analysis in the conveying roll component due to the load on the roll and thermal stress analysis in the component of low pressure die casting machine. In the power plant, FEM is applied in the frame holder of generator to get stress due to static and dynamic load. Requirement properties of material frame holder of generator is stable, high strength, high stiffness, high corrosion resistance, and etc. In this research focus on the stress in the frame holder of generator translation and rotation motion on vertical direction. Varying load and material has been used for frame holder of generator such as cast iron, stainless steel, steel and thermoplastic resin. In the previous study, frame holder of generator has been used from cast iron and thrust force direction come from horizontal direction. The results get the maximum value (σmax) of von mises of generator is is 643.4 MPa and the deflection value is 6.13 mm. By applied of vertical thrust force direction on the frame holder of generator translation and rotation is found that the maximum stress von misses value σvmis 74845 MPa and displacement is 17.9 mmby load 10 KN and using cast iron to frame holder of generator material.
