摘要

This paper studies the Mei symmetry and Mei conserved quantity for nonholonomic systems of unilateral Chetaev type in Nielsen style.The differential equations of motion of the system above are established.The definition and the criteria of Mei symmetry,loosely Mei symmetry,strictly Mei symmetry for the system are given in this paper.The existence condition and the expression of Mei conserved quantity are deduced directly by using Mei symmetry.An example is given to illustrate the application of the results.
