Virtual flexible body deformation operation simulation system supporting haptic feedback

The invention discloses a virtual flexible body deformation operation simulation system supporting haptic feedback. The system is characterized by adopting a novel physical significance-based equal pitch conical helical spring haptic modelling method, wherein in the method, the superposition of the sum of the deflection of each layer of equal pitch conical helical spring is externally equal to the deformation on the surface of a flexible body; and the sum of the consumed external force when each layer of equal pitch conical helical spring which is connected with adjacent layer of equal pitch conical helical spring initially contacts is equal to a given virtual contact force of a given surface of the flexible body. The modelling method is simple; the deformation calculating process is simple and convenient; and higher precision of deformation simulation can be guaranteed. The system can better simulate virtual deformation simulation when a virtual agent presses the flexible body and can make operators actually sense haptic information in a simulation process in real time in an interactive process.
