Abstract

Abstract: In allusion to the problem that the electromechanical coupling system of the pure electric tractor under the low speed and heavy load condition was affected by the non-periodic impact interference force, which produced the strong dynamic load, caused the nonlinear torsional vibration and had serious influence on the reliability and durability of the electromechanical coupling system of the pure electric tractor, the nonlinear torsional vibration model of electromechanical coupling system of pure electric tractor was established to solve the equilibrium point of the undisturbed Hamiltonian system, considering the coupling effect of rotor torsional angle and the electromagnetic torque. And the Melnikov method was adopted to calculate the bifurcation threshold curve, which further analyzed the influence of dynamic mechanical load on the nonlinear dynamic behavior of electromechanical coupling drive system of a pure electric tractor. The research results indicate that the electromechanical coupling drive system of pure electric tractor is characterized by the complex dynamic behaviors such as periodicity, quasi-period and chaos. If the dynamic mechanical load f<3.6, the system is a periodic motion; if 3.6
