The invention discloses an elastic moment simulation device. The elastic moment simulation device comprises an elastic component used for providing an elastic moment; the elastic component is radiallyarranged along a spindle; the upper end of the elastic component is connected to the spindle; and a clamping device used for fixing is arranged on the lower part of the elastic component. The elasticmoment simulation device with the structure has the advantages that a mode that the elastic component is axially arranged is replaced by the mode that the elastic component is radially arranged alongthe spindle, so that axial space occupation is greatly reduced; and the whole equipment is more compact.
