摘　　要：应用正交试验法对稻壳模压夹具中的夹板模型进行了有限元分析,通过极差分析获得了影响夹板结构性能因素的主次顺序,即夹板厚度→垫板作用力中心线距夹板几何中心的距离→上模具重力作用中心线距夹板几何中心的距离→夹板宽度,并且结合有限元模型的验证分析确定了夹板结构的合理方案。The orthogonal experiment method was applied for finite element analysis of splint which was one part of jig used in rice hull mould processing.Sequence of priority of factors which affected splint structural performance was obtained by range analysis.The ranking was splint thickness,distance between acting force central line of the plate and geometric centre of splint,distance between gravity central line of upper mould and geometric centre of splint,width of splint.Proper structural concept of splint was got by integrating check analysis of finite element moldel.
