Abstract

The invention discloses a comprehensive experimental platform for a track of a planar four-rod mechanism of an electroactuated material and an experimental method thereof. The comprehensive experimental platform for the track of the planar four-rod mechanism of the electroactuated material is used for fitting a movable track of the planar four-rod mechanism of the electroactuated material. The experimental platform comprises a rack, a driving module I and an electroactuated rod. The planar four-rod mechanism is arranged on the rack. The planar four-rod mechanism comprises an input rod, a connecting rod and a connecting frame rod. The driving module I is used for driving the planar four-rod mechanism of the electroactuated material to move. One end of the electroactuated material is fixed to the connecting rod and a voltage V1 is applied while the other end of the electroactuated material is suspended and a voltage V2 is applied. By arranging the driving module I to drive the planar four-rod mechanism to move, a moving track O1 as reference is generated at the other end of the electroactuated rod. By applying two voltages to two ends of the electroactuated rod, the electroactuated rod made from an electroactuated polymer material is bent and deformed, so that a fitting track O2 is generated at the other end of the electroactuated rod, and therefore, the fitting rack of the fourrod mechanism is obtained.

Description

technical field [0001] The invention relates to a comprehensive experiment platform and an experiment method thereof in the technical field of experimental instruments, in particular to a comprehensive experiment platform and an experiment method thereof for the trajectory of an electric-actuated material plane four-bar mechanism. Background technique [0002] In the mechanism design of the feeding system of forging equipment, the planar linkage mechanism is the most widely used and most basic mechanism. The planar linkage mechanism has the following advantages: the pressure per unit area of ​​the kinematic pair is small, and the surface contact is easy to lubricate, so the wear is reduced; it is easy to manufacture and easy to obtain high precision. The disadvantages of the planar linkage mechanism are: in general, the planar linkage mechanism can only approximate the given motion law or trajectory, and the design is more complicated; when the given motion requirements are ...
