The invention discloses a synthesized test bed of composite structure, which is characterized in that a vibration exciter is fixed on a test bed; one end of a delaying vibration rod is inserted into the vibration exciter hole and the other end thereof is connected with one end of a cross beam at the end of the vibration exciter; a platform on which a guide way is installed is positioned at one side of the test bed; a cross beam at the end of a slide block is vertical to the guide way; one end of the cross beam at the end of the slide block is fixed on a slide block connecting plate and is connected with the cross beam at the end of the vibration exciter or a mass block by a cross beam connecting plate; four piezoelectric patches or ferroelectric patches are respectively pasted at the two sides of the cross beam connecting plate to form piezoelectric or ferroelectric composite structure; and two displacement sensors are installed on supports at the two sides of the cross beam connecting plate respectively and
