Based on the method of auxiliary equation,the paper uses two auxiliary equations with function-transformation and one auxiliary equation of hyperbolic function type to construct an important model in mechanics,which has solutions of new trigonometric function type of wave equation with fifth-order strong nonlinear term and the exact solitary wave solutions of hyperbolic function type, obtained via the symbolic calculation system of Mathematica.The method has general meanings in searching for other new exact solutions to the nonlinear evolution equation with fifth-order strong nonlinear term.
