Abstract:
The 10 mm×10 mm energy absorbing device used for steam generator lower horizontal support, and its stiffness experiment, including material selection, experimental scheme, equipments and load exerting are briefly introduced. Then, the formulas of the load exerting vs displacement for the energy absorbing bar are formulated, and the experimental stiffness of the energy absorb device in the region of elastic and ductile are deduced from the formulas. Also, the curve of the load exerting vs residual displacement for the energy absorb device is obtained by the experimental data. All of which provide lots of conveniences for the energy absorb device used in steam generator lower horizontal support.
