摘要
虚功准则法是理性准则法,在结构优化设计中应用非常广泛,但以前对其求解时均忽略结构的自重及惯性载荷,导致虚功准则法准则不准,结果不优,所以本文基于有限元法以桁架结构为例推导考虑自重及惯性载荷的虚功准则法方程组,并优化迭代求解公式。
The formula method of virtual work which was extensively applied in the structure optimization design is the rational formula method,but the dead weight and the inertia load of the structure were neglected in the past solution of the equation of virtual work,which resulted in the inaccuracy of the formula and result.Based on the finite element method and the girder construction the paper deduced the equation of the formula method of virtual work in which the dead weight and the inertia load of the construction were considered,and optimized the solving formula.
