Simulation of haptic force feedback interaction using virtual model

Due to the massive calculations of force feedback, and the difficulty in haptic scenes and graphic scenes refreshing, the real-time force feedback interactive technology in virtual model is studied. Based on the research of force feedback simulation model, a mechanical simulation model using material scrapers rate is presented. This model can calculate the scraping of force feedback according to the amount of material per unit time. The effectiveness and stability of this mechanical model is verified by experiments. The influencing factors of calculation precision and accuracy in this simulation model are pointed out. From the investigation on 12 students, we find that virtual model making system is relevant and efficient. The experiment results demonstrate that the adopted method can add an effective haptics to students and can be widely used in computer-aided industrial design field. 1548-7741/
