ANALYSIS OF STATIC AND DYNAMIC CHARACTERISTICS OF SLOTTED CYLINDRICAL SPRINGS

Abstract

Slotted cylindrical springs are a unique and unusual type of spring with a special 3D shape. There is little or no literature on the behavior of this type of spring under static and dynamic loads. In this study, the authors studied the characteristics of springs under static and dynamic loads using the finite element method with the help of Abaqus software. The case studies include a 3-slot sawn spring and a 4-slot sawn spring, impact and static load analysis, and compare the results. The results show that slotted cylindrical springs are more complicated when subjected to compression related to deflection due to static or dynamic loads. This special type of spring is capable of absorbing loads to a range that conventional springs cannot. It can be clearly seen that the 4-groove spring has higher stiffness than the 3-groove spring. In the case of impact loading, the results show that the deformation process increases steadily according to the determined curve. This demonstrates the superiority of slotted springs when subjected to dynamic loads.
