The Vehicle system in general is very concerned with the comfort and safety of the driver. One of the determining criteria for vehicle safety is the use of a good suspension system. The vehicle suspension system is investigated in this work is a railway car which is a modification of the TATA ACE EX-2 pickup vehicle. Based on the modification of pickup vehicles, the trajectory of pickup vehicle specifications varies, so it is necessary to pay attention before and after modification, as well as high vibrations. In this study, the researcher used manual mathematical calculations and the finite element method with his SOLIDWORKS software to perform a quantitative analysis of leaf spring suspension systems for track-finding vehicles. Based on the results of vibration testing conducted, it is known that the frequency that occurs is 4.27 Hz, but the simulation results show that the frequency of the front leaf springs is 199.67 Hz, 351.18 Hz, 356.91 Hz, 648, and 57 Hz. This shows that it varies between 739.42 is hertz. The rear leaf spring frequencies are 206.83 Hz, 286.4 Hz, 346.05 Hz, 636.33 Hz, and 715.68 Hz. This means that no destructive resonance occurs in the leaf springs. © 2024, Semarak Ilmu Publishing. All rights reserved.
