Özet
Although layered leaf springs operate under bending moment in most engineering applications, they are also subjected to torsional loads. Friction losses, spring cross-sectional geometries, lengths, number of layers, and fixation methods affect torsional behavior. In this study, the torsional behavior of leaf spring systems made of AISI1065 and AISI1080 steels with different numbers and lengths of layers was investigated experimentally, numerically, and analytically. Experimental results were evaluated for bars with a cross-sectional geometry of 35 mm×2.78 mm, between 500 mm and 650 mm, and for shorter bars with a thinner cross-sectional geometry of 25.4 mm×1.57 mm, between 250 mm and 300 mm in length. Numerical results were used to determine the spring lengths to be used experimentally, and the variation of the required torques in spring systems with different lengths and number of layers for a torsional angle of 0-90° was investigated. Experimental, numerical, and analytical results were compared. It has been observed that while the difference between the analytical and numerical results remains below 5% as the number of layers increases, the difference between these results and experimental results can reach up to 15%. For the same number of layers, it has been seen that the amount of torque required to reach a certain torsional angle increases as the length of the spring system decreases, and this increase is even greater with increasing number of layers and torsional angle.
