基于改进弹簧振子模型的实时肌腱模拟
Real-time Tendon Simulation Based on Improved Mass-spring Model
摘要
Abstract
In order to conduct real-time simulation for human tendon in rebuilt system of Anterior Cruciate Ligament(ACL), a real-time tendon simulation method based on improved mass-spring model is proposed. By defining non-linear spring, the probability of "super-elasticity" in linear spring model is cut down, which enhances the simulation effect of tendon force. The approach of adding temporary restriction springs is used to deal with collision, and the implicit backward Euler method is also used to solve the model. The real-time performance and integrity of simulation is promoted. Experimental results show this method meets the system requirement of real-time and realistic sense.关键词
