| Abstract |
The acceleration performance function and
dynamic performance evaluation combining the
acceleration, velocity, gravity and external force of a
2‐DoF planar parallel mechanism are presented in this
paper. By means of the principle of virtual work, the
inverse dynamic model and acceleration performance
function of the planar parallel mechanism are setup.
Based on the factors in the acceleration performance
function, the effect on the acceleration performance of
parallel mechanisms is investigated. Then a new method
considering the acceleration factor, velocity factor,
gravity factor and external force factor for dynamic
performance evaluation of the parallel mechanism is
introduced, which can evaluate the dynamic
performance of high‐speed parallel mechanisms more
exactly. Based on this method, the evaluation indices
used in dynamic optimization are introduced. These
indices overcome the limitation of commonly used
indices, and lay the foundation for dynamic
optimization of parallel mechanisms. |
