Abstract
ABSTRACT WITH the development of the piezoelectric force transducer it has become possible to measure directly the time dependent contact force during impact of a uniform viscoelastic sphere with a solid flat surface. This paper develops the second order nonlinear differen-tial equation. and proposes it as a model for the motion of the sphere's center of gravity during impact. The seven parameters (m,k,c,T,y,v0,v,) are determined for a silicone rubber ball. These parameters are then used in a numerical solution of the differential equation and compared with the measured force of the impact. Three methods of direct measurement of the para-meters from the contact force are discussed. The first two methods use formulas for the coefficients of the power series solution for the contact force which contain the parameters as variables. The third method involves a direct least-square fit of the differential equation to the measured force.
