摘要
本文以部分框架为计算单元,在原有Ρ—Δ法的基础上,推出了精度较高的的二阶简化计算公式,本文公式应用方便且精度较高,便于手算,可供设计人员参考.
A framework segment is used as an element for calculation.Formulas involving effects of P-Delta are derived,based on the already existing P-Delta method.Formulas presented in this paper are desirably precise and convenient for ready reference.
