Visualization Of Finite Element Analysis Deformation Results Based On Hololens, Jinli Xu, Zhou Zheng
Visualization Of Finite Element Analysis Deformation Results Based On Hololens, Jinli Xu, Zhou Zheng
Journal of System Simulation
Abstract: An UWP application of virtual review of the finite element analysis based on Microsoft HoloLens is developed by using Unity3D software. A set of programs are completed to realize three-dimensional solid static finite element analysis in Matlab. To realize the visualization of the deformation effect, the useful information of the finite element analysis result is extracted and exported to VTK file, then converted into DAE file. A vertex shader is written in Unity3D software to realize the color display and the visualization of deformation effect of one-sided model, and finally the UWP application is released to HoloLens. The test …

Impact Analysis Of Gun-On Target Parameters On The Blunting Effect Of The Soft Protective Human Body, Sun Fei, Wenmin Yan, Junbin Zhang, Yongjuan Wang, Xu Cheng
Journal of System Simulation
Abstract: In order to research the blunt impact effect of target-entry parameters of pistol bullets, the finite element models of the soft upper body of the pistol blunt with a soft-protected human body are developed. By hitting the heart, lung, liver and stomach at three target-entry velocities, the impact response of pistol bullet impacting on human torso with soft armor is numerically calculated by finite element method. The simulation results quantitatively reveal the pressure transmission mechanism of the human body with blunt body armor at different target speeds and positions and the law of blunt impact response at different target …

Optimized Analysis Of Milling Thin-Wall Parts Based On Shell Element Models, Yusong Liao, Han Jiang
Journal of System Simulation
Abstract: As to milling the thin-wall part accurately, here with the finite element model composed of SHELL elements, the effects of lowering position, size of the part and cutting parameters to the deformations of the thin-wall part were analyzed and compared, and the corresponding theoretical analysis was provided. The conclusions can be got as; the model composed of SHELL elements can analyze the factors causing the deforroations of the thin-wall part and optimize the cutting method and cutting parameters effectively to improve the machining accuracy and efficiency.
