摘要

This paper investigates structure equation and Mei conserved quantity of Mei symmetry of Appell equations for non-Chetaev nonholonomic systems.Appell equations and differential equations of motion for non-Chetaev nonholonomic mechanical systems are established.A new expression of the total derivative of the function with respect to time t along the trajectory of a curve of the system is obtained,the definition and the criterion of Mei symmetry of Appell equations under the infinitesimal transformations of groups axe also given.The expressions of the structure equation and the Mei conserved quantity of Mei symmetry in the Appell function are obtained.An example is given to illustrate the application of the results.
