宽板弯曲过程中板厚的变化规律
【摘要】 对宽板弯曲变形过程进行分析 ,提出了弯曲过程中板坯外表面半径 ,板料厚度和变薄系数随板坯内表面半径变化的理论解 ,并与查表法和近似解作了比较。
【Abstract】 By analyzing the wide sheet bending,the variations of theoretic radius values of outer surface,sheet thickness and thinned coefficient with radius of inner surface in bending were put forward.The results were compared with testing data and approximate values.
