摘要

Over the past few decades, one of the biggest problems facing engineers has been dynamic analysis under the effect of moving forces. These kind of loading is widely used in many different industries, which has made it necessary to evaluate how lively structures respond dynamically to these moving loads. The paper presents a dynamic response of stiffened curved plates under the influence of moving forces at different constant speeds, utilizing the finite element method (FEM) for the investigation. The deflections at diverse locations of the plates can be evaluated by solving the dynamic equations of motion using the Newmark- \(\beta\) β method. The dynamic deflection results are compared with FEAST software. A parametric analysis is conducted for various shape, size, loading conditions (moving loads with various constant velocities) and stiffener disposition.
