In order to verify the rationality of flexible object deformable model, the force-deformation model validation system was established, which consists of wireless data transceiver platform based CC2531, force sensor measuring platform, and displacement measurement platform based FALCON hand controller. The relationship between interactive force and deformation in the elastic deformation experiment and impaling experiment with the experimental object of fresh pig liver was studied. Based on the data of force and deformation, the parameters were confirmed and amended. The simulation results show that the characteristic of force and deformation is consistent with actual measurement. The proposed system can be utilized for verifying general deformable models, which will lead to more applications in haptic based medical simulation.
