织物和静电极板参数对静电吸附力的影响分析OA北大核心CSTPCD

With the continuous advancement of textile and garment production processes,traditional fabric handling methods heavily reliant on manual labor are gradually insufficient for the demands of intelligent development.In addressing the issue of fabric handling,industrial robots currently employ various methods such as mechanical grasping,needle puncture,vacuum suction,and electrostatic adsorption.In comparison to traditional methods like mechanical arm gripping,needle puncture,or vacuum cup suction,electrostatic adsorption stands out as an ideal approach due to its stable adhesion force and high-precision gripping.Therefore,this paper opts for electrostatic adsorption technology to address the challenge of fabric handling in garment production.In the realm of electrostatic adsorption technology research,prior studies have predominantly focused on areas such as climbing robots and mechanical arms,with relatively limited systematic analysis in the field of fabric handling for garments.Building upon electrostatic adsorption technology,this paper delves into the transfer of garment fabrics,aiming to gain a profound understanding of the electrostatic adsorption force model.Through a systematic exploration of the impact patterns of fabric and electrostatic plate parameters on electrostatic adsorption force,the paper aims to provide a scientific foundation for the design and optimization of electrostatic plates. To enhance the adhesion performance of electrostatic plates during the transfer of garment fabrics,this paper focused on warp-knitted fabrics,establishing a three-dimensional electrostatic adsorption model and a five-layer two-dimensional electrostatic adsorption model to provide scientific basis for the design and optimization of electrostatic plates.Firstly,the paper established a structural model for warp-knitted fabrics and a theoretical model for electrostatic adsorption force,ensuring the effectiveness of the research through theoretical analysis and simulation verification.Secondly,employing the Maxwell tensor method,the paper derived a five-layer two-dimensional theoretical model for electrostatic adsorption force,thoroughly investigating the impact patterns of internal structural parameters on adhesion force.Finally,through the optimization of structural parameters in the design of electrostatic adsorption plates,the paper aimed to enhance the adhesion performance of these plates,so as to provide theoretical support for the intelligent handling of garment fabrics.By introducing a five-layer two-dimensional electrostatic adsorption force model and employing the Maxwell stress tensor method for analysis,this paper extensively explored the impact of internal structural parameters on electrostatic adsorption force,offering a theoretical basis for more accurate predictions of electrostatic adsorption force.Simultaneously,the paper suggested the existence of optimal solutions for plate width and the distance between electrostatic plates,proposing adjustments to these parameters to enhance the overall adhesion performance of electrostatic plates. Research findings indicate that by establishing a theoretical and simulation-based electrostatic adsorption model,the effect of electrostatic adsorption force on the warp-knitted fabric structure in an electric field is verified.The effectiveness and feasibility of the simulation method are confirmed.The magnitude of electrostatic adsorption force generated by the electrostatic plate is jointly influenced by plate voltage and plate structural parameters.Adjusting plate voltage and structural parameters enhances plate adhesion performance.Notably,in designing the electrostatic plate structure,an optimal proportion exists between plate width and the distance between electrostatic plates.Optimization suggests maintaining a ratio of around 0.78 between plate distance and electrode width to maximize overall electrostatic plate adhesion performance.Electrostatic adsorption technology injects new vitality into the textile and garment production industry,improving production efficiency by automating fabric handling and transfer processes.The introduction of this technology not only innovates the mode of production,but promotes the textile and garment industry to move towards a smarter and more efficient direction.
