基于NASTRAN的装配体连接螺栓有限元分析

Assembly Bolts Finite Element Analysis Based on NASTRAN

通过有限元分析软件MSC.Nastran,建立了简单的计算模型,用多点约束单元对装配体中常见的螺栓连接进行近似模拟。得到了螺栓处刚性节点载荷,并利用第4强度理论对螺栓进行了校核。

Two computational models are established by FEM technique and the MSC NASTRAN software program. Assembly bolts are simulated by using MPC. The paper gets grid forces and checks the theory of Von-misses and the intensity of assembly bolts.
