Abstract:A new conserved quantity deduced from Mei symmetry of Tzénoff equations for holonomic systems is studied.The expression of this conserved quantity and the determining equation to induce this conserved quantity are presented.The results indicate that this new method is easier to find conserved quantities than previously reported method.Finally,application of this new result is presented by a practical example.
Keywords:holonomic systems  Tzénoff equations  Mei symmetry  new conserved quantity
