基于ANSYS的重载纤维模塑托盘结构与性能研究

Research on structure and capability of heavy-dutyfiber moldingpallet based on ANSYS

以一种新型重载纤维模塑托盘为研究对象,利用有限元分析软件对其模拟分析与结构优化。通过ProE软件对重载纤维模塑托盘进行建模,在ANSYS软件中对其整体与局部结构进行模拟分析。利用正交试验方法,设计并优化托盘结构。结果表明:正六边形面孔的面板最大应力最小,面孔的优化尺寸为面孔深度22 mm、壁厚6 mm、拔模角度2°、倒角半径6 mm。支腿的优化尺寸为拔模角度2°、厚度25 mm和倒角半径15 mm。优化的重载纤维模塑托盘在6 t均布静载荷作用下,所受到最大应力为41.86 MPa,小于重载纤维模塑材料极限应力。正六边形面孔板具有更好的承载性能;影响面孔与支腿结构单元强度的主要因素是拔模角度和厚度;优化后的重载纤维模塑托盘结构强度能够达到重载要求。

With the new heavy-duty fiber molding palletas the research object,the work aims to simulate its state of force and optimize structure by finite element software.Model of the heavy-duty fiber molding pallet was established by ProE software,and global and local structurel statics was analyzed in Ansys software.The pallet structure was designed and optimized by orthogonal test.Analysis of structure static showed that the maximum stress of the panel with hexagonal holeis the smallest.Optimum size of panel holeis depth of 22 mm,thickness of 6 mm,taper angle of 2 DEG,the fillet radius of 6 mm.Optimum size of outriggers is taper angle of 2 DEG,depth of 25 mm,the fillet radius of 15 mm.Under the condition of uniform load of 6 tons,the maximum stress is 41.86 MPa,which is less than the limit stress of heavy-duty fiber molding materials.In conclusion,the panel with hexagonal hole has better bearing capacity.The main factors affecting the strength of panel hole and outriggers is the draft angle and thickness.After optimization,the structural strength of heavy-duty fiber molding pallet can meet the requirements of heavy load.
