摘  要:
核桃破壳取仁技术是核桃深加工工艺中的重点。为此,根据核桃的几何尺寸参数,用软件建立了核桃有限元分析模型,对核桃在3种气压载荷加载方式下的受力状态进行应力与应变分布分析。分析结果表明,在0.55 MPa载荷时核桃结蒂位置加载是最优解,核桃壳体爆开位置较好,多处破裂有利于取仁工作,可以得到较高的破壳率和较低的碎仁率,证明此有限元分析模型具有可行性。

摘  要:
Breaking walnut shell is the key of processing walnut.According to the geometry parameters of walnut,a walnut finite element analysis model is established with software.Through the analysis of the load stress state stress and strain distribution under three kinds of pneumatic loading ways,we have obtained the analysis results that when a load is loaded at hole A at 0.55Mpa,the walnut shell burst open position is the best and it is the optimal solution.More rupture positions more conducive to breaking hull work and being able to get a higher breaking rate and a lower loss rate.We have proved the feasibility of this finite element analysis model.
