The invention relates to a large-torque multifunctional shimmy tester for testing an elastic shaft coupling and detecting the relevant parameters comprising a dynamic damping coefficient, a static damping coefficient, rigidity, durability (fatigue life) and the like of the elastic shaft coupling. The tester comprises a hydraulic servo system, measurement and control hardware, measurement and control software, a force/motion switching mechanism, a sensor detecting device and a connecting device. The tester is characterized in that a hydraulic cylinder is connected with the force/motion switching mechanism based on the spiral transmission of balls through a connecting device, and the straight reciprocating motion of a piston rod is switched to the left and right reciprocating swing of an output member so that static and dynamic torsion swing tests on the elastic shaft coupling are realized; the hydraulic cylinder can also be directly connected with the elastic shaft coupling through theconnecting device so that
