The equivalent parameters of the pantograph are important for improving the design and advancing the capability of the producers. The nonlinear motional differential equation of the pantograph is derived from the Lagrange equation. The nonlinear model of pantograph is linear zed to establish the function expression of the equivalent parameters. And the dynamics simulation of pantograph was completed by the Newton-Euler method. Take the study on TSG3 pantograph as an example to validate the model. The present results indicate that the mechan- ical models have the guidance meaning for the design of pantograph.
