The generator is a machine component that converts mechanical energy into electrical energy. Generators can be found in power generation systems. In this paper, generators are used on the sea wave power plants [1-4]. This generator works by utilizing the effects of ocean waves that rise and fall so as to push the piston to move in the same direction with ocean waves. The performance of the generator is influenced by the magnitude of the force of the piston, rotors and stator. Stable, rigid and smooth piston movements also can increase generator output performance. The design and material of the generator holder is very influential on the generator stiffness. Generator stiffness includes deformation and stress that occur and can be obtained using the finite element method (FEM) [5-13]. In this paper focus on simulating the generator holder shape horizontal direction and the amount of deformation and stresses by varying frame holder generator shape and inclination (75 0 , 80 0 , 90 0 ). In previous studies, the translational motion generator frame holder design is less rigid (stable). From the simulation results, the maximum voltage value (σ max ) of von mises is 6,427 MPa, the deflection value is 61.29 mm with 90 0 generator stand design positions.
