【摘要】 本文根据赫兹接触应力理论,对于杆件纵向撞击面的局部变形问题,提出了一个非线性的理论模型,并得到了求解撞击入射应力波的差分计算公式。运用文献[1]提出的电算法获得的撞击入射应力理论波形与实测波形是非常接近的,较以前的理论模型更为优越。此外还简要地阐述了撞击面特征参数h的物理意义、重要性和实验测定方法。更多还原

【Abstract】 A nonlinear theoreti al model of the partial deformation on longitudinally striken surface of bars based on Hertz’s theory of contact stress is presented, and therefore a solution for incident striking stress wave may be obtained by use of difference equation. As a result,a theoretical in ident stress wave plotted by calculating with digital computer shown in literature[1] is more close to the waves to be observed. Such a new theoretical model appears preferable to others. In addition, physical meaning and measuring procedure of the characteristic parameter h of striken surface and its significance are briefly stated更多还原
