Almost all the fields use tree modeling in society, so it analyses the tree modeling in the academic circles. But it is difficult to find an efficient tree modeling method because its own complexity and wind, rain acting on tree. The object suffers rain power that the force calculated by momentum theorem. And then compare the value of rupture limit to Young modulus. It is determined object to fracture or sway. Then it constructs tree dynamic modeling in the nature.

Almost all the fields use tree modeling in society. But it is difficult to find an efficient tree modeling method because its own complexity and wind, rain acting on tree. This paper constructs tree static modeling with expanding 2.5D modeling method and collision principle. The object suffers wind power that the force calculated by momentum theorem. And then compare the value of rupture limit to Young modulus. It is determined object to fracture or sway. Then it constructs tree dynamic modeling in the nature.

In order to construct tree modeling, the method is that it is divided into static modeling and dynamic modeling. This paper focuses on the analysis of the key problems in tree dynamic modeling. The object suffers wind power that the force calculated by momentum theorem. And then compare the value of rupture limit to Young modulus. It is determined object to fracture or sway. Then it constructs tree dynamic modeling in the nature.

Tree Modeling

Nowadays, tree modeling is used in various fields of social widely. Existing tree modeling method ignore trees their own feature so that it construct modeling could not express lifelike tree morphology and then depict the effects attitude of wind and rain and other natural factors in nature. This paper discusses tree dynamic modeling to express the tree multicolored under the wind or rainfall area. Using the theorem of momentum to calculate the instantaneous momentum, and compared to rupture limit, and then depict the state of tree break or mutual extrusion.

Abstract The cable-driven segmented manipulator with cable-constrained synchronous rotating mechanisms (CCSRM) is a new type of continuum manipulator, which has large stiffness and less motors, and thus exhibits excellent comprehensive performance. This paper presents a dynamic modeling method for this type of manipulator to analyze the friction and deformation of the cables on the dynamical behaviors of the system. First, the driving cables are modeled based on the ALE formulation, the strategies for detecting stick-slip transitions are proposed by using a trial-and-error algorithm, and the stiff problems of the dynamic equations are released by a model smoothing method. Second, the dynamic modeling method for rigid links is presented by using quaternion parameters. Third, the connecting cables are modeled by torsional spring-dampers and the frictions between the connecting cables and the conduits are considered based on a modified Coulomb friction model. Finally, the numerical results are presented and verified by comparing with experiment results. The study shows that the friction and cable deformation play an important role in the dynamical behaviors of the manipulator. Due to these two factors, the constant curvature bending of the segments does not remain.
