摘要

均匀厚度贝勒维尔弹簧（UBS）能够承受更大的载荷，而且体积相对较小、结构紧凑，因此在许多应用中适合替代螺旋弹簧。本文对锥形贝勒维尔弹簧（TBS）进行了实验、数值和理论分析。本文介绍了用不锈钢合金（SS304）制造的法向锥形贝勒维尔弹簧（NTBS）的实验结果。非线性弹塑性有限元模拟结果与实验结果相当吻合。介绍了基于季莫申科板理论的修正系数，以匹配 NTBS 的有限元分析（FEA）结果。反向锥形贝勒维尔弹簧（RTBS）分析表明，与 UBS 和 NTBS 相比，它能存储更多的弹性应变能。对 TBS 的几何参数进行了优化研究，以获得空刚度区域的最大能量吸收。

Experimental, numerical, and theoretical analysis of tapered belleville spring

Uniform thickness belleville springs(UBS) are a suitable replacement for coil springs in many applications due to their ability to take higher loads and their relatively small and compact size. This paper presents an experimental, numerical and theoretical analysis of the taper belleville spring(TBS). Experimental results on a normal taper belleville spring (NTBS), fabricated from stainless steel alloy (SS304), are presented. Non linear elastic-plastic finite element simulations support the experimental behaviour reasonably well. A correction factor based on Timoshenko’s theory of plates, to match the finite element analysis(FEA) results for NTBS, is presented. Reverse taper belleville spring (RTBS) analysis shows that it can store more elastic strain energy than UBS and NTBS. An optimisation study on TBS geometrical parameters is performed to attain maximum energy absorption for the null stiffness region.
