The present invention discloses anequipment and method for evaluating the dynamic coordination of five-digit forces, which can generate stable deflection torques in different directions during grip, and establish a finger dynamic coordination calculation method based on a multi-layer composite network. The grip test equipment comprises a test device and a processor. The test device is configured to measure three-dimensional force vectors and three-dimensional torque vectors generated when subject's five fingers grasp the test analyzer and coordinate data of fingertip pressure center points. The processor is configured to acquire the three-dimensional force vectors and three-dimensional torque vectors of the five fingers and the coordinate data of the fingertip pressure center points measured by the test device, and construct a multi-finger dynamic coordination network based on a recursive network; calculate characteristic parameters of the multi-finger dynamic coordination network; measure a structure indicator of the multi-finger dynamic coordination network by using the characteristic parameters of the multi-finger dynamic coordination network; and evaluate the gripcoordination of the fingers according to the structure indicator of the multi-finger dynamic coordination network.
