Static performance evaluation and optimal design of 5-DOF parallel mechanical leg
To evaluate the static performance and design optimally a parallel mechanical leg for the six-legged robot
a static analysis method based on the mapping of both constraint and actuation forces was proposed
and the mechanical leg was designed based on this method. Firstly
the constraint and actuation Jacobian matrixes were established based on the mapping of both constraint and actuation. Then
according to the virtual work principle
the actuation statics transmission equation was established
the performance evaluation indexes of actuation statics were designed
and the relationship curve between the performance evaluation index and structure parameters was calculated. By the same way
the transmission equation and performance evaluation index of constraint statics were obtained
and the relationship curve between the performance evaluation index and structure parameters was also calculated. Finally
based on the performance evaluation indexes both of constraint and actuation statics
the structure parameters were optimally designed by Monte Carlo method. Calculations show that when the structure parameters of a fixed platform and a movement platform are 200 mm
and 80 mm and the UPU branched chain lengths l
1min
l
1max
are 500 mm and 900 mm
the statics comprehensive performance of the parallel mechanical leg is the best. These studies lays the theoretical foundation for further study of the six-legged robot.
