基于先进科技对准规格的减缩,对准仪量测数据的应用也变得更为重要。不同对准策略的选择所引起的结果,对全部对准预算有很重要的影响。介绍两个主要科技研发项目:先进对准配套和对准标的设计。     

A variable stiffness parameters method for a quasi-steady rolling problem

In this work a variable stiffness parameters method (VSPM) is proposed to a quasisteady rolling problem with slightly compressible, rigid-viscoplastic and isotropic hardening material model and nonlinear Coulomb friction law. The problem is stated in the form of a variational inequality, containing nonlinear and nondifferentiable terms. Under certain restrictions on the material characteristics, the convergence of the VSPM is proved and existence and uniqueness results are obtained. The applicability of the VSPM, combined with the finite element method, is shown, as an example problem is solved numerically.
