摘　　要：介绍了基于Optistruct求解器实现子模型法的3种方式,等参定量对比3种子模型法和全局模型法,计算结果表明:FIELD子模型方法计算结果同全模型存在差异,但差异可忽略不计;FBD子模型则完全一致;TCL子模型方法同全模型位移场、应力场相对误差分别为3.1%、5.7%。应用FBD子模型法简化计算不失为一条经济、高效率的途径。This paper introduces three ways to implement the sub-model method based on the Optistruct solver.The isoparametric quantitative comparison of the three sub-model methods and the global model method shows that the calculation results of the FIELD sub-model method are different from the full model,but the difference can be negligible;the FBD sub-model is completely consistent;the relative errors of the TCL sub-model and the full model displacement field and stress field are 3.1%and 5.7%,respectively.Applying the FBD sub-model method to simplify the calculation is an economical and efficient way.
