摘要
本文用二维光弹性方法研究了垂直载荷对哈氏棒应力分布的影响。发现在垂直载荷作用下棒的棘齿区呈现高应力集中,棘齿区应力高于光滑区,棘齿区应力值受垂直载荷影响最大,棒的前侧各点应力与垂直载荷呈线性相关。当增加水平载荷作用后,哈氏棒应力分布发生变化。
The influence of vertical loads upon the sttresses of HDR was studied with photoelastri-city. Experiments showed; the stresses of HDR were in direct proportion to vertical loads; the stresses on ratchet part were higher than those on smooth part; the stresses on anterior border ofHDR were higher than those on posterior border. Changes of stress distribution occurred when hori-zontal forces were loaded. There was severely stress concentration on the junction of the ratchet partt and smooth part.
