This study focuses on the nonlinear dynamic characteristics of gear transmission systems and the backtracking of geometric and kinematic errors. The core research contents include: First, establish a typical gear transmission system model, taking into account internal and external excitation factors such as stiffness excitation, error excitation, meshing impact excitation, rotational speed variation, torque oscillation and load fluctuation. Quantitatively reveal the inherent parametric connections and coupling mechanisms between multiple nonlinear factors and dynamic structures, and propose methods to improve motion stability and optimize dynamic performance; Second, construct a multi-gap coupled collision dynamic model, comprehensively incorporating tooth side clearance, radial clearance, their coupling effects, and the influence of meshing stiffness on gear clearances, and propose an optimization design method for gear collision dynamics with good global stability; Third, for typical gear transmission systems, extract various factors affecting their geometric and kinematic errors and their occurrence probabilities, build a part-level, component-level and system-level error analysis model for gear transmission systems, and propose backtracking methods for geometric and kinematic errors of gear transmission systems.
