EFFECT OF HEAT TREATMENT AND CROSS SECTION ON THE CRASHWORTHINESS OF 51CRV4 SPRING STEEL

In this study, the 51CrV4 spring steel was used as crash box material and its crashworthiness was investigated. Crash boxes with cylinder and rectangular geometries were designed in SolidWorks and nonlinear finite-element analysis was performed in HyperWorks software. In addition, 51CrV4 spring stee...

Description
Summary:In this study, the 51CrV4 spring steel was used as crash box material and its crashworthiness was investigated. Crash boxes with cylinder and rectangular geometries were designed in SolidWorks and nonlinear finite-element analysis was performed in HyperWorks software. In addition, 51CrV4 spring steel was subjected to three different heat treatments and their mechanical properties were determined by tensile and hardness tests. The crashworthiness of structure was evaluated taking into account the total energy absorbed, peak force and the specific energy absorbed. It has been observed that heat treatment and geometric changes have a serious impact on crashworthiness.
