【摘要】 本论文以棕榈藤家具为研究对象,在研究藤家具的概况和棕榈藤藤材主要特性的基础上,对藤家具质量评定的内容展开深入探讨。具体内容包括藤家具外观质量、典型部件和结点力学性能、整体力学性能的评定项目和检验方法的研究。这一系统性的探索研究,为制定藤家具质量评定标准提供了基础性的技术参考。目前,该标准已在送审过程中。同时,研究也有助于推动企业实现藤家具产品的优化设计,提高我国藤家具的质量和国际竞争力。主要研究结论如下:(1)分析、总结了藤家具及棕榈藤材的基本内容,并对单叶省藤藤皮和藤芯材料的含水率、轴向抗拉强度和抗霉性能进行了测试研究。研究得知:两种材料含水率相差不大,一般在10～11%之间,都是优良的藤编材料。在尺寸相近的条件下,头层藤皮的轴向抗拉性能优于扁平藤芯;二层藤皮的抗拉性能优于头层藤皮;三种藤芯材料中,半圆藤芯的轴向抗拉性能最优。藤皮编织面层的抗霉性能优于藤芯编织面层。(2)藤家具外观质量评定的特色在于对编织面层编排质量的检验方法研究:密实型、通透型编织面层分别引用间隙差值和空隙差值作为衡量指标,实现了量化控制。相邻间隙(空隙)差值越小,编排质量越好。(3)藤家具典型部件和结点的力学性能研究为藤家具整体力学质量评定提供了有力的参考依据。1)编织面层是藤家具的典型部件,在抗弯力学性能评定试验中,它体现了良好的弹性特点。在尺寸相同或相近的情况下,密实型编织面层的抗弯性能优于通透型;密实型藤皮编织面抗弯性能优于密实型藤芯编织面;机器编织面层抗弯性能略大于手工编织面层。2)T型、L型是藤家具的典型结点形式。经正交试验和方差分析得知,连接件、缠结方式、缠结材料和基材四个因素对T型抗拉、抗弯强度的影响均显著。缠结材料对抗拉强度影响显著程度相对较小,基材对抗弯强度影响显著程度相对较小。另外,包角斜接形式的L型结点抗弯性能最好,其余两种结构形式的L型结点抗弯性能相对较差。(4)经大量试验验证,藤家具整体力学性能评定可基本参照《GB/T 10537.1～10537.6家具力学性能试验》中相应内容,仅在耐久性试验加载次数上有改动。更多还原

【Abstract】 On the basis of the research on the main characteristics of rattan materials and the general situations of rattan furniture, this dissertation studied deeply on the quality assesses of rattanfurniture. With the main research object of the rattan furniture, it consisted of three parts——the quality assesses and test methods of the appearance performances, the mechanical properties of the typical component parts and joints, and the mechanical properties of the holistic products. This systemic, exploratory research provided a basic and technical reference for establishing the standard of assessing rattan furniture quality. At present, this standard has been sent for examining and revising. Simultaneity, the research will also contribute to the more excellent designs of rattan products in the enterprise, and enhance our products’ quality and competitive power in the world.The main research results are as follows:(1) The dissertation analyzed and generalized the basic conditions of the rattan furniture, rattan cane and its derivatives (materials for weave).The moisture content, the axial tensile strength, and mildew resistance of the rattan peel and the rattan core of Calamus simplicfoilius Wei. (one rattan species) have been tested: The rattan peel and the rattan core have approximate moisture contents (between 10%～11%), and they also the fine weaving materials .With the similar sizes, the axial tensile strength of the flat peel is better than the flat core; the axial tensile strength of the peel is better than the flat core; Among the three kinds of the rattan core, the axial tensile strength of the half-round core is the best. The mildew resistance of the weaving surface made of the rattan core is better than the one made of the flat peel.(2) The characteristic of the quality assess of the appearance performances is the research of the quality assess of the layout in weaving surface: The gap margin and distance margin for the close-grid and open-grid surface were referred as the indexes of dimension. The smaller the margins are, the finer the quality of the layout in weaving surface is.(3) The study on the mechanical properties of the typical component parts and joints will provide a good reference for the research of the mechanical properties of the holistic products.1) Weaving surface is a typical component part with good flexibility. In the condition of similar or same size, the flexing resistance of the close-grid one is better than the open-grid one; the flexing resistance of the close-grid one made of the rattan flat peel is better than the one made of the core; the flexing resistance of the weaving surface made by machine is better than the one made by hand.2) T-type and L- type are the typical forms of the rattan furniture joints. The results from the orthogonal tests and the variance analysis have showed that: the connections, the wrapping methods, the wrapping materials, and the species of the rattan cane all have significant effect on the tensile strength and bending strength of T-type joint. Correspondingly, the wrapping materials have smaller effects on the tensile strength, and the species of the rattan cane have smaller effect on the bending strength. Otherwise, the angle-wrapping miter L-type joint has the best bending strength, the bending strengths of the other two forms of L-type joint are relatively poor.(6)A mass of the feasibility tests have showed that: the quality assesses and test methods of the mechanical properties of the holistic products can refer to the corresponding contents in the national standard named "GB/T 10537.1～10537.6 Test of Mechanical Properties of Furniture". Only the loading times in durability tests need to be modified.更多还原
