摘要：

A reformulation and solution is presented of the equations of impulse and momentum for an arbitrarily shaped rigid body striking a flat massive surface. The model makes use of the classical coefficient of restitution, e, and tangential coefficient, mu . The latter is defined as the ratio of the tangential to normal impulse components. It is shown that a distinction between mu and friction coefficients, f, is necessary for a proper interpretation of impact data. The expression of impact energy loss is placed into a particularly convenient form. Comparisons are made of this impact model to others from the field of solid particle erosion and wear.
