Embodiment Construction
[0047] The overall processing flow of the present invention is as figure 1 As shown, the key steps are to construct the governing equations based on viscoelastic mechanics and use the smooth particle hydrodynamics method to realize the calculation of the motion state of the meshless particle model. The following describes the implementation of each step in detail in accordance with the order of the overall flowchart.
[0048] 1. Construct the governing equations for soft tissue deformation simulation
[0049] Almost all biosolids are viscoelastic. This invention overcomes the defect of using a simple elastic model to reflect the mechanical properties of soft tissues in order to pursue real-time performance in the traditional technology, and strives to improve the accuracy of deformation simulation while taking into account real-time The linear viscoelastic equation is used to reflect the mechanical properties of soft tissue.
