The invention belongs to the technical field of
robot simulation, and particularly relates to an
SCARA robot dynamics
simulation method and device, and the method comprises the steps: modeling and preprocessing; establishing a material
database; in the
simulation software Adams, a screw rod nut and a spline nut are split into a
stator fixed to a mechanical arm and a rotor rotating relative to the
stator, and corresponding
mass and
inertia are given to the split
stator and rotor based on material attributes of an
SCARA robot dynamic model; the base, the mechanical arm and the motor
assembly are endowed with
mass and
inertia; and simulation analysis is carried out, specifically, constraint and
coupling relations among the base, the mechanical arm, the motor
assembly and the lead screw
assembly are added, a driving function is constructed, and simulation analysis is carried out. According to the method, the motion characteristics of the
SCARA robot are fully considered,
part type selection is supported under the condition that no test prototype exists, the accurate motion trail optimization direction is provided, and the dynamics
simulation error is reduced.
