Abstract: This paper deals with finding Lagrangians for damped, linear multidegreeoffreedom systems. New results for such systems are obtained using extensions of the results for single and two degreeoffreedom systems. The solution ...

Abstract: A simple transformation is used to obtain the first integrals and the solutions of the Duffing–van der Pol type equation under certain conditions. It is shown that the system can be totally integrable and this total ...
