非线性振动干燥机板簧曲面有限元分析与优化（Finite Element Analysis and Optimization on Leaf Spring Curved Surface of Nonlinear Vibration Dryer）
振动干燥机 板簧曲面 屈曲变形
2009/12/28
针对线性非共振式振动干燥机工程上存在的问题，提出应用非线性振动理论，将其改进为非线性近共振双质体振动干燥机，简述了其工作原理，分析筛板可能承受系统突加载荷作用下的最大横向力，进行板簧曲面屈曲变形分析。研究表明：考虑物料粘度随温度而变化以及粒度不均匀性等因素而产生的突加载荷是正确的；板簧曲面由此发生屈曲变形而导致筒体的横向失稳是可能的。基于ANSYS软件建立了分析模型,解得板簧曲面各阶屈曲变形，可有...
