| Abstract: | A primary analysis and explanation of the working mechanism of an energy absorber by the friction of steel balls was presented. Based on the stress characteristics of rock bit loading and ball deformation, the equivalent elastic modulus and resistance characteristic of energy adsorption by the friction of steel balls were obtained. Then, the reflective properties of steel balls, optimum cross section ratio of absorber to drill rod, energy-absorption coefficient and reasonable length for the column of ball were obtained by using the wave principle. This study can provide reference for the design of energy absorber by frictions of steel balls. |
