Dynamic Analysis of a Timoshenko Beam Subjected to an Accelerating Mass Using Spectral Element Method

Figure 11

Normalized Displacement under the equivalent moving loads with the initial speed given by 𝜏=0.5. 𝛽=0.03. (a) 𝜆=1, (b) 𝜆=0, and (c) 𝜆=−1. Solid line: without neglected; dashed line: with inertia force neglected; dotted dashed line: with Coriolis force neglected; dotted line: with centrifugal force neglected; bold dotted line: with tangential force neglected.
