摘　　要：本文应用光弹性贴片法和云纹法对GN-12型拖拉机新、老机架造行应力场的测定和比较,并对机架的改型提出了具体意见。由于节材,可获得较大的经济效益。结果表明,该方法用于薄壁钢结构应力测定是有效的。In the present papcr, the measurements and comparisons of a stress field for the ncw and old frame of a tractor arc made by the photoclastic-coating mothod and the moirc mcthod. Somc concrete propositions to change the form of a tractor's frame are put forward, subsiantial cconomic profits can be amassed. It is shown that the two mcihods are admirably applicable to the stress mcasurement of thc thin-walled steel structure.
