the force characteristics of the planar 3-DOF 3-RRR parallel mechanism is studied.The inverse kinematics and Jacobian matrixof the mechanism are analyzed.The linear formof the driving torque is deduced.Then
based onMatlab software
the kinematics analysis of mechanism is carried out
and the results are compared with the resultofADAMS software.At last
the variation lawof driving torque and reaction force of the mechanismare obtained.The resultsof this study can provide necessary information forstiffness analysis
dynamic performance analysis
optimization design and system control of the 3-RRR parallel mechanism.
