| 1 | 管状机织物与管子之间的摩擦系数测量系统显示文摘为了实现管状机织物与管子之间摩擦系数的测量,设计了一套管状机织物在管子上抽拔过程的摩擦系数测量系统。首先通过施加弹性元件的方法,在实际使用工况下测试出附加摩擦力,再测试计算出弹性元件在圆管上产生的正压力,根据计算公式μ(摩擦系数)=F(摩擦力)/N(正压力)直接计算出摩擦系数;同理,通过弹性气压法测出管织物与管内壁的摩擦系数。然后使用所测量的摩擦系数在LS-DYNA分析软件中建立有限元模型进行计算,并与试验数据进行对比分析。最后,针对该摩擦系数测量系统在探月三期工程中月壤钻进取芯组件上的应用效果进行了实验检测与仿真计算对比。结果表明该系统测得的管状机织物在管子上抽拔过程的摩擦系数准确可靠,为有限元分析模型中摩擦系数的确定提供了一种有效的测量方法,满足月壤取芯组件的应用要求。 | 钱秀洋 王洪鑫 殷参 孟炜杰 文桂林 | 2016 | 仪器仪表学报2016，37，12： | 2 |
| 2 | Tribological interactions of 3D printed polyurethane and polyamide with water-responsive skin model显示文摘3D printing in the textile and fashion industry is a new emerging technology.Applications of 3D printing for designing clothes and other wearable accessories require tribological and biological understanding of 3D printing plastics against the complex human skin to mitigate skin-friction related ailments such as calluses and blisters.This study provides tribological insight in search of an optimal 3D printable material that has minimal friction against the skin.Two low friction 3D printable materials,thermoplastic polyurethane(TPU)and polyamide(TPA)were chosen and tribological testing was carried out against a water responsive skin model.The skin model was synthesized using a gelatine based model made with cotton and crosslinked with glutaraldehyde.Tribological testing of TPU/TPA against the skin model in dry and wet conditions were made.The higher coefficient of friction(COF)was observed in the wet condition compared to the dry condition.To overcome the higher friction,TPA/TPU-sodium polyacrylate composites were prepared by heat pressing that significantly reduced COF of TPU and TPA by~40%and 75%,respectively,in wet conditions. | Ashish K.KASAR Ashton CHAN Victor SHAMANAEV Pradeep L.MENEZES | 2022 | Friction2022，10，1： | 1 |

| 4 | Finite-element modelling of frictional behaviour between oesophagus and endoscope显示文摘The endoscopy is the most direct and effective means for digestive tract diseases.Medical workers can conduct a series of manipulations with the help of endoscope,including checking,removing,stripping the diseased tissue or placing the stent.In order to understand the frictional behaviour at the endoscope-oesophagus interface,the finite-element model was analysed by Abaqus in this study.Considering the different modelling conditions,the total force due to frictional stress,frictional dissipation and the maximum Mises stress for the whole model were studied.Results showed that with the increasing amplitude,coefficient of friction and decreasing diameter,the total forces due to the frictional stress and the FD increased obviously.It did not present a clear difference with the variable distance for overlapping parts(region L).The positions of maximum Mises stress for the whole model under different conditions mainly focused on the initial part of the region R.The maximum Mises stress between different diameters showed a big difference.The results can provide the basic data for the finite-element modelling of frictional behaviour of human tissue. | Chengxiong Lin Pan Ren Wei Li Hengyi Deng Zhongrong Zhou | 2020 | Biosurface and Biotribology2020，6，3： | 0 |
| 5 | 湿态织物与皮肤间摩擦特征的影响因素研究显示文摘为调查摩擦方式下湿态织物黏性感知的摩擦特征影响机理,开发织物与模拟皮肤间的摩擦装置,提取4项可用于表征黏性感知的摩擦特征指标,选取服装市场常见的21种织物作为试样,调查不同织物性能、织物含水量饱和度、法向载荷及滑动速度对于织物与皮肤间摩擦特征的影响。结果显示,织物表面粗糙度与最大静摩擦力显著负相关(r=-0.535,p<0.05),织物拉伸伸长率与静摩擦力增长速率显著负相关(r=-0.683,p<0.05);随着织物含水量饱和度增大,最大静摩擦力、黏着变形量和动摩擦力平均差呈增大趋势;随着法向载荷增大,最大静摩擦力、黏着变形量和动摩擦力平均差呈线性增大;随着滑动速度增大,静摩擦力增长速率基本呈线性增大,动摩擦力平均差呈减小趋势。 | 师琅 姜茸凡 | 2024 | 纺织科学与工程学报2024，41，1： | 0 |
