Abstract

The two-post lift is often used to lift light or medium-sized cars. The lift system generally raises cars for easy access to wheel assemblies and the vehicle's underside. This paper presents the design considerations and stress analysis of the arms for a two-post car lift. In design consideration, material selection and data collection must be done. Therefore, steel standard AISI 1045 is selected. This research aims to design the calculation of arms that can lift a maximum load of 1460 kg with a maximum height of 1800 mm. The thickness of the arm and maximum bending stress are calculated by using bending theory. In design calculation, the allowable stress of the arm is 132.5 N/mm2 , the working stress is 115.73 N/mm2, and the maximum von-Mises stress is 115.74 N/mm2 . Also, the effective strain is 5.021x10-4 . To know the maximum von Mises stress of the arm for a two-post car lift, the static structural analysis is done by using the SolidWorks software 2024. When the theoretical and simulation results of the arm are compared, the deviation results of the arm are 3.6% for von Mises stress, 2.6% for deflection, and 11.96% for effective strain.
