摘要：

以100 kN的砝码加载过程为研究对象,从理论上提出一种消除逆程现象的方法。首先提出一种独立平滑加载方法,保证组合出的力值逐渐增大或者减小,使力值曲线平滑;并且建立数学模型,找到加载时进入平滑加载时间的有效区间;然后用Matlab进行仿真分析与优化。仿真优化结果表明:运用独立平滑加载从理论上可以消除逆程现象。

Abstract: With 100 kN weight loading process as the research object, it puts forward a way to eliminate the phenomenon of blanking in theory. Firstly, it put forward a independent smooth loading method, and ensure the combination of strength gradually increases or decreases, and smooth the force value curve. Mathematical model is set up to find the smooth loading time t in the effective range. Then simulation analysis and optimization is done by Matlab.
