Research On Modeling And Structure Design Of Eucalyptus Laminated Veneer Lumber

Fast-growing eucalyptus is one of the main three species in the south, which plantingwidely and is the main raw material for man-made board. But the defects in fast–growingeucalyptus have seriously limited utilizing degree of wood. Making use of eucalyptus toproduce and develop laminated veneer lumber furniture is an effective and important way toease contradiction between wood supply and demand, play advantage of eucalyptus resource inGuangxi, promote Guangxi forestry economy development, realize the fast-growing highvalue-added use and meet the requirement of furniture market. To play advantage of laminatedveneer lumber material to design and produce furniture to satisfy the furniture market will bethe trend of furniture industry. This dissertation is the first study on fast-growing eucalyptuslaminated veneer lumber furniture in a comprehensive andsystematic as following severalaspects:1. Fast-growing eucalyptus is made into laminated veneer lumber product by pressing andproducing on one's own in the laboratory, its density, water content, the modulus of elasticity, thestatic music intensity, etc, have been tested. The appearance, structure features, physical andchemical characteristics of laminated veneer lumber are analyzed and studied, and by makingcomparison to the real wood lumber in the mechanical properties, the material characteristics offast-growing eucalyptus laminated product have been put forward, also the inspiration formodern furniture design.2. The furniture using fast-growing e ucalyptus laminated veneer lumber has uniquematerial characteristics and fashionable stripe. In furniture modeling design with laminatedveneer lumber, first analyze appearance characteristics including color, texture, material quality,and then make comprehensive utilization of the material characteristics. Combined with thebionics, emotional design, semiotics, and other modern design theory in main steam, thisdissertation discusses the laminated veneer furniture design further.3. To get good texture effect, fast–growing eucalyptus laminated veneer lumber must gothrough bleaching and dyeing. The best process for eucalyptus wood veneer dyeing andbleaching have been determined through the experiment, and do experiment for the materialmachining properties in fast-growing eucalyptus laminated veneer lumber. By comparing withCedar wood which made for furniture in Guangxi constantly, ensure fast-growing eucalyptusveneer layer of material have excellent machining performance in the cutting, planning,accumulate sanding, molding and drilling further.4. Fast–growing eucalyptus laminated veneer lumber structure design of furniture product material is a key component of this paper, fast–growing eucalyptus laminated veneer lumberfurniture can be combined with glue, tenon and structure fittings. Researching deeper for thetenon joint through different tenon joint methods to find out the strength, have made sure theelliptical tenon is the best way for laminated veneer lumber furniture combination. In addition,three different kinds of screws for nail-holding ability of fast–growing eucalyptus laminatedveneer lumber have been discussed as well. ABAQUS finite element software have analyzedspecial bending structure used in laminated veneer lumber furniture, the modern green structuredesign theory have been held together.5. Based on design practice and instance, the design method of exploiting and developingthe new product of fast–growing eucalyptus laminated veneer lumber furniture have been putforward, and make technical economy evaluation for the development of new product have beenraised to offer manufacturing enterprise of the furniture the reference and application.
