Harvester&#39;s behaviors under different conditions are simulated in MATLAB using the analytical model. Natural frequency, maximum deflection, and stress are calculated with greater precision using eigen frequency and stationary analysis using COMSOL Multiphysics. At a base excitation of 2 g and a resonant frequency of 4.38 Hz, the simulated results showed that the developed energy harvester prototype could generate up to 14 V of AC output voltage and 550 mW of output power. These findings highlight the promising potential of the proposed energy harvester for transforming train mechanical energy into electrical power. This energy harvester&#39;s viability and dependability for real-world applications in monitoring railway tracks are supported by developed analytical and simulation models.</span></span> COMSOL Multiphysics, Energy harvester, Train-induced vibration, Railway track monitoring. 83 94 http://ijeee.iust.ac.ir/browse.php?a_code=A-10-5049-2&slc_lang=en&sid=1 Shuvojit Kundu theshuvojit@gmail.com 1800319475328460016032 1800319475328460016032 No Shuvojit Kundu, Information & Communication Engineering, Hannam University, Daejeon, South Korea Tuhel Ahmed a.tuhel71@gmail.com 1800319475328460016033 1800319475328460016033 No Tuhel Ahmed, Information & Communication Engineering, Hannam University, Daejeon, South Korea JIA UDDIN jia.uddin@wsu.ac.kr 1800319475328460016034 1800319475328460016034 Yes Jia Uddin, AI and Big Data Department, Endicott College, Woosong University, Daejeon, South Korea.
