This example shows the static simulation of a parallel flexure guide which moves from -20 mm deflection up to 20 mm deflection in x-direction (the degree of freedom of the parallel flexure guide). Goal is to evaluate the translational stiffness in the supporting directions (y- and z-direction) of the end-effector over the range of motion. | This example shows the static simulation of a parallel flexure guide which moves from -20 mm deflection up to 20 mm deflection in x-direction (the degree of freedom of the parallel flexure guide).
