Cloth Modeling Based on Particle System

引用

Journal of Donghua University(English Edition) 2001年第2期18卷 41-44页

作者： Zhong Yueqi(钟跃崎) Wang Shanyuan(王善元) college of Textiles Dong Hua University Shanghai 200051 College of Textiles Dong Hua University Shanghai 200051

A physical-based particle system is employed for cloth modeling supported by two basic algorithms, between which one is the construction of the internal and external forces acting on the particle system in terms of kes-F bending and shearing tests, and the other is the collision algorithm of which the collision detection is carried by means of bi-section of time step and the collision response is handled according to the empirical law for frictionless collision With these algorithms. the geometric state of parcles can be expressed as ordinary differential equationswhich is numerically solved by fourth order Runge- Kutta integration. Different draping figures of cotton fabric and wool fabric prove that such a particle system is suitable for 3D cloth modeling and simulation.

Gene of animal keratin can be inoculated into cotton fiber and thus get the keratin transgenic cotton fiber through transgenic technology. Handle of two kinds of pure cotton poplin, one of which is made of the keratin transgenic cotton while the other is made of the ordinary cotton of the same breed as control group and both with absolutely identical spinning, weaving, and dyeing process, was objectively evaluated with kes system. The result of analysis indicates that the principal changes of keratin transgenic cotton fabric are that the bending and shearing property of the fabric are considerably enhanced, KOSHI (Stiffness) and HARI (Anti-drape stiffness) of the fabric are good, while SHINAYAKASA (Flexibility with soft feeling) and SHARI (Crispness) decline.

An Efficient Way of Fabric Simulation

引用

Journal of Donghua University(English Edition) 2002年第1期19卷 44-48页

作者：钟跃崎王善元 college of Textiles Dong Hua University Shanghai 200051

A partide system model is presented for the simulation of fabric draping. The interaction of each partide is based on a refined mass-spring structure. Regarded the fabric material as an orthotropic continuum, the refinement of our model is focused on the construction of mechanical responses of bending and shearing springs by means of a piecewise polynomial approximation of kes-F testing data. In this way, the draping figure of a silk fabric, a wool fabric and a polyester fabric are simulated. The static final shape and animation of simulation proves that our model has developed an efficient technique on real fabric- drape modeling, and the little computation time of the simulation execution on a PC with Celeron 450 CPU may meet the requirement of real-time simulation.

Journal of Textile Science and Technology 2016年第2期2卷 22-30页

作者： Liberato Venant Haule college of Engineering and Technology University of Dar es Salaam Dar es Salaam Tanzania

The effect of extended laundering on cotton fabric treated with Dimethylol dihydroxyethyleneurea (DMDHEU) easy care finish was investigated and the fabric characterised by crease recovery performance and the Kawabata Evaluation System for Fabrics (kes-F). The kes-F results indicated that the mechanical handle properties of the DMDHEU treated cotton fabrics were affected by both the levels of application of the DMDHEU easy care finishes and the stress relaxation of the fabrics in aqueous conditions.

Speeds of Sound and Excess Isentropic Compressibilities of Butyl Acetate＋Aromatic Hydrocarbons

引用

Chinese Journal of Chemical Engineering 2008年第4期16卷 599-604页

作者： Bal Raj Deshwal Anu Sharma Krishan Chander Singh Department of Chemistry All India Jat Heroes Memorial College Rohtak-124001 India Department of Chemistry Maharshi Dayanand University Rohtak-124001 India

Speed of sound data for butyl acetate＋benzene, or toluene, or o-xylene, or m-xylene, or p-xylene binary mixtures have been measured over the entire range of mole fraction at 308.15 K. The excess isentropic compressibilities （ Ks^E ） were computed from speed of sound and density data, derived from molar excess volume data. The Ks^E values were analyzed by using graph theoretical approach. The Ks^E values evaluated by graph theory compared reasonably well with their corresponding experimental values. The Ks^E data were also expressed in terms of Redlich-Kister polynomial equation to derive the coefficients and the standard deviation.

Photoelectron imaging of resonance-enhanced multiphoton ionization and above-threshold ionization of ammonia molecules in a strong 800-nm laser pulse

Chinese Physics B 2019年第6期28卷 140-145页

作者： Le-Le Song Ya-Nan Sun Yan-Hui Wang Xiao-Chun Wang Lan-Hai He Si-Zuo Luo Wen-Hui Hu Qiu-Nan Tong Da-Jun Ding Fu-Chun Liu Institute of Atomic and Molecular Physics Jilin UniversityChangchun 130012China Jilin Institute of Chemical Technology Changchun 132022China Jilin Provincial Key Laboratory of Applied Atomic and Molecular Spectroscopy Jilin UniversityChangchun 130012China college of Electronic Science and Engineering State Key Laboratory on Integrated OptoelectronicsJilin UniversityChangchun 130012China

In this work, we mainly investigate the NH3 molecular multiphoton ionization process by using the photoelectron velocity map imaging technique. Under the condition of femtosecond laser(wavelength at 800 nm), the photoelectron images are detected. The channel switching and above-threshold ionization(ATI) effect are also confirmed. The kinetic energy spectrum(kes) and the photoelectron angular distributions(PADs) are obtained through the anti-Abel transformation from the original images, and then three ionization channels are confirmed successfully according to the Freeman resonance effect in a relatively low laser intensity region. In the excitation process, the intermediate resonance Rydberg states are C^1 A 1(6 + 2 photons process), B^1 E(6 + 2 photons process) and C^1 A 1(7 + 2 photons process), respectively. At the same time, we also find that the photoelectron angular distributions are independent of laser intensity. In addition, the electrons produced by different processes interfere with each other and they can produce a spider-like structure. We also find ac-Stark movement according to the Stark-shift-induced resonance effect when the laser intensity is relatively high.
