To reveal the nonlinear dynamic behavior of gear rattling vibration caused by backlash, a 2-DOF oscillator model with spring and damping elements was established. Based on theory discontinuous dynamical systems, phase plane motion divided into three parts: domain tooth surface meshing motion, free back motion. Introducing global mapping local dynamics method, process teeth from impact to then a...

Image-based computational modeling offers a virtual access to spatially and temporally high resolution flow and structural mechanical data in vivo. Due to inter-subject morphological variability, mesh generation represents a critical step in modeling the patient-specific geometry and is usually performed using unstructured tetrahedral meshing algorithms. Although hexahedral structured meshes ar...

Standard PolyCube-based hexahedral (hex) meshing methods aim to deform the input domain into an axis-aligned PolyCube volume with integer corners; if this deformation is bijective, then applying inverse map voxelized yields a valid hex mesh. A key challenge in these maintain bijectivity of deformation, thus reducing robustness algorithms. In work, we present interactive pipeline for that sidest...

We present a new algorithm to mesh an arbitrary piecewise linear complex in three dimensions. The algorithm achieves an O(n log∆ + m) runtime where n, m, and ∆ are the input size, the output size, and spread respectively. This represents the first non-trivial runtime guarantee for this class of input. The new algorithm extends prior work on runtime-efficient meshing by allowing the input to hav...
