This paper considers the scheme design and structure design of wire the drive based on the controlling system of WEDM-LS.Using the software Recurdyn,the contact among flexsible bodies and nolinear deformation of the wire drive system is simulated the wire drive mechanism is.dynamically animated and the dynamical force on each wire drive wheel axis and the tension on each key point ale calculated.It improved the structure and dynamics propertie of wire drive mechanism.ensured the working robustness and increased the precision of the machine.
