What do springs do?

Desarrolla el conocimiento de los niños de los principios básicos del diseño y la tecnología. Presenta un muelle y luego explora cómo se utiliza en diferentes y cada vez más complejos aparatos y máquinas. Las ilustraciones y fotografías ayudan a explicar su funcionamiento. Las actividades permiten a los niños investigar los principios del resorte por sí mismos.

Design, testing, and simulation of fibre composite leaf springs for heavy axle loads

This paper summarizes the design, manufacturing, testing, and finite element analysis (FEA) of glass-fibre-reinforced polyester leaf springs for rail freight vehicles. FEA predictions of load-deflection curves under static loading are presented, together with comparisons with test results. Bending stress distribution at typical load conditions is plotted for the springs. The springs have been mounted on a real wagon and drop tests at tare and full load have been carried out on a purpose-built shaker rig. The transient response of the springs from tests and FEA is presented and discussed.
