T The design of fatigue test equipment requires analysis before the production process is carried out. The analysis was carried out using the finite element method, with the aim of knowing the strength, stiffness, and fatigue life of the design of the fatigue test equipment. Stress analysis is used to determine the strength of the structure. While modal analysis is used to determine the stiffness of the structure. And fatigue analysis is used to determine the fatigue-life of the design structure. The software used is Altair HyperMesh and Altair HyperLife for preprocessing, Altair OptiStruct as a solver, and Altair HyperView for postprocessing. Based on the simulation results of stress analysis, with the loading in the form of a force generated by the actuator of 600 N, it is known that the maximum stress that occurs is 46.726 MPa on the WL Damper 2 component and the maximum deformation is 0.709 mm at the end of the lever component. By comparing the yield strength of the SS400 material used, it can be concluded that the design of the fatigue test equipment is strong enough. The results of the modal analysis simulation show that the personal frequency value in mode 1 is 76.37 Hz. While the system works at a frequency of 60 Hz. So that the design of this fatigue test equipment avoids resonance conditions. The results of the fatigue analysis simulation show that all components have a fatigue life greater than 1020 cycles with stress loading that occurs in the stress analysis simulation.
