Then change to Dynamics Explicit Analysis
Step, set at 10 s. To reduce the operation time, a
mass scaling factor is used to scale 106
Reducing time and using mass scaling may
result in increased kinetic effects and errors.
According to Abaqus Manual, as long as the
kinetic energy/internal energy of the structure is
less than 10%, the result can be considered
reliable.
Contact pairs
General Contact(3×3、3×3×5)
Constraints
First, a reference point is established at the fixed end
of the model, coupled with the fixed end of the model,
and a fixed constraint is added to the reference point,
so that the size of the support counter force of the
reference point is also the corresponding force size of
the entire model.
Advantages
1. Constraints that rotate around the axial can be added
2. Easy axial pull, torque, shear, bending curve graph for the entire
model
