摘要
本文旨在探讨振动试验中L型夹具在不同加强筋(角钢、槽钢、空心矩形钢)配置下的固有频率变化.首先计算了无加强筋L型夹具的固有频率,并通过ANSYS模态仿真验证其准确性.随后,针对采用角钢、槽钢及空心矩形钢作为加强筋的L型夹具进行了仿真分析.结果显示,空心矩形钢加强筋显著提升了夹具的固有频率,这归因于其较高的惯性矩和优越的抗弯性能.本文最后总结了研究成果,为相关领域的振动控制提供了参考.
Abstract
This paper aims to explore the variation in natural frequency of L-shaped fixtures in vibration tests under different configurations of reinforcing ribs(angle steel,channel steel,hollow rectangular steel).First,the natural frequency of L-shaped fixtures without reinforcing ribs was calculated and verified for accuracy through ANSYS modal analysis simulation.Subsequently,simulations were conducted for L-shaped fixtures using angle steel,channel steel,and hollow rectangular steel as reinforcing ribs.The results showed that hollow rectangular steel significantly increased the natural frequency of the fixtures,attributed to its higher moment of inertia and superior bending resistance.Finally,the paper summarizes the research findings,providing a reference for vibration control in related fields.
