Abstract

This research studies the shaft strength of a BLDC electric motor. A Shaft is one of the components in a rotary engine and functions to transmit power. The design calculation is needed to determine the effect of the strength of the material being treated. The strength analysis of the shaft used FEM (Finite Element Method). The shaft is modeled on the manufacturing design and tested by numerical simulation with Ansys Mechanical 14.5-BRIN commercial license software. The static simulation used a structural statics module with static and dynamic load input. The research method comparing the results of FEM simulations with two different types of materials is determined. Based on the simulation parameters, the selected material types are JIS S45C tempered and AISI 1045 cold-drawn. The simulation results represent the maximum stress (von Mises) and total deformation. The deformation value of S45C tempered material is slightly higher than that of AISI 1045 cold drawn. However, both materials have the same maximum von Mises stress. Keyword: AISI 1045, Cold drawn, Finite Element Method, Shaft, Static Structure, S45C, Tempered.

Abstract

Abstrak Perkembangan mesin-mesin elektrik terutama Bow Thruster bagi sektor kemaritiman sangat signifikan. Dari beberapa komponen penting dalam Bow Thruster, rotor terutama poros dan bantalan bearing mempunyai peran penting sehingga  perlu dilakukan analisa. Analisa dinamik merupakan analisa untuk mengetahui sifat-sifat dinamik rotor akibat pengaruh putaran terhadap frekuensi pribadi. Pada makalah ini analisa dinamik dikembangkan dengan pemodelan rotor menggunakan Euler-Bernoulli Beam (EBB). Hasil dari analisa dinamik rotor ini menunjukan putaran kritis dan modus getar dari rotor Bow Thruster. Kata kunci : Rotordinamik, Euler-Bernoilli Beam, Poros, Putaran Kritis, Modus Getar. AbstractThe development of electric machines, especially Bow Thruster, for the maritime sector is significantly increased. The several important components in Bow Thruster, rotors, especially shaft and bearings, have an important role to analyzed. Dynamic analysis is an analysis to determine the dynamic properties of rotors due to the effect of rotation on natural frequency. In this paper a dynamic analysis, rotor modeling was developed using Euler-Bernoulli Beam (EBB). The results of this rotor dynamic analysis show the critical speed and mode shapes of the Bow Thruster rotor. Key Words : Rotor Dynamic, Euler-Bernoulli Beam, Shaft, Critical Speed, Mode Shape.
