For the high-order Maggi equation of nonholonomic systems,when it meets certain condi-tions,the Maggi equation can be transformed into a Birkhoffian system.By constructing the generating function,the system is investigated numerically using the symplectic geometric algorithm of the Birkhof-fian system.Compared with the above-mentioned algorithm with the classical Runge-Kutta method,Birkhoffian symplectic scheme is very accurate in a long-term tracing.
