The invention discloses a tool for a workpiece test and an experimental method. The tool comprises a swing arm main assembly and a counter-force frame assembly. The counter-force frame assembly is fixed with a torsion beam of a workpiece; the swing arm main assembly is connected with guide vertical plates at the two ends of the workpiece torsion beam, and the swing arm main assembly applies forcesto the guide vertical plates to enable the workpiece to deform; The torsion beam of the workpiece is fixed through the counter-force frame assembly, the swing arm main assembly is connected with theguide vertical plates at the two ends of the torsion beam of the workpiece, longitudinal and transverse double-channel composite periodic dynamic loading is applied to the workpiece through the swingarm main assembly, and whether the workpiece deforms or not is judged; or whether the rigidity, the toughness and the fatigue meet the automobile production requirements or not is judged according tothe deformation size, the st
