Shanghai Daoqin Plastics Co., Ltd.

in analysis mold product design in in issues upper, utilizing plastics mold product design and manufacturing research 虚拟现实 and 虚拟原 type technology and 理论, mold product design, application WTK虚拟 ring development 程序, achieve and CAD formed and data 共享, large improve/increase mold enterprise add 入WTO rear new product development market competition force.

一, 引 言

随 经济 full and market competition day 益激烈, plastics mold product design positive 面临严峻考验. mold enterprise must utilizing most new technology, in most short time inner development high quality, low cost, high add value plastics raw materials product, most fast speed degree and market. this need 改变传统 mold product design methods, using/adopting product design technology, plastics mold 现代 product design technology is Knowledge design, it need comprehensive utilizing tube/pipe 理, control, system engineering, true, 信息建模, 人工智 can, data and 网络通讯 and other technology, will mold product design process in 信息流 has machine formed, 并模拟出 mold product future property can, and mold manufacturing full process for mold product design effect/influence, from 而做出 positive 确 决策 and design solution/scheme.

plastics mold product manufacturing is type mono parts small amount, dispersion type production. mold product development from design, made to product upper cycle long, design process in difficult and use 户进行交流, difficult and 时听取 use 户 意见, difficult 以考虑 can manufacturing property and can assembly property, very difficult comprehensive safety, and other requirements, can comprehensive production, time and use and other versus made conditions made, more upper 考虑整 mold product lifespan cycle more issues. application CAD technology must in mold product full 部出 之 rear, can and use 户进行交流. in addition, upper mold product 因缺乏直观 property, has mold product manufacturing rear can 发现诸 more issues, formed mold product can combined use requirements, effect/influence 交货期, also increase cost, has 时甚至 effect/influence 客户关系 and market has rate.

二, mold product design and manufacturing concept 提出

虚拟现实 technology formed machine 图形学, more 媒体, 人工智 can, 网络, more device, 并行处理 and other technology most new research formed 果. 实时 三维空间 performance force, machine 交互 操 as ring can to belt/tape its 境 感受. 随 际互联网 technology and, 虚拟现实 technology will formed is product design technology and standards. mold product design technology is 虚拟现实 technology in mold product manufacturing in application or achieve. it is mold design ring and manufacturing ring 境 计算 machine internal 映射, is manufacturing important inner 容. mold manufacturing is true technology, 虚拟现实 technology and other is 支撑, for mold design, processing, assembly, 维护经 统一建模形 formed ring 境, process, product.

三, mold product system 构造

1.构造 mold product system frame 架

soft parts 方面包括造 type, 视觉仿 true, for control, frequency 空间化 and soft parts. type soft parts use 定义虚拟 ring 境, material and is 特征. 视觉仿 true soft parts for ring as 实时渲染. for control is use control for 象状态以 and ring 境交互 soft parts frame 架. frequency 空间化 soft parts is according to 三维虚拟 ring generate 声源 工 tool, can in and use in true 实空间 versus for 应 位置 soft parts.

soft parts using/adopting 三维虚拟现实 development soft parts WTK, its function strong/high large, various 虚拟现实输入, 输出工 tool equipment, from most simple to 6 自由 degree equipment, from machine device to tool has 位置跟踪 头戴式立体显示 device, use can in short inner 建立起实时 三维图形 application system.

hard parts 方面包括计算 machine system, device, 位置/ direction device, 三维(六维)输入 plant/unit and 立体发生 device. machine system tool has 实时视觉仿 true;位置/ direction device tool has 当信息输入 to application 程序时, use 跟踪头部, 手, tool and direction function;三维(六维)输入 plant/unit use can and application or 虚拟空间 in for 象进行交互.

2. mold product system specific achieve technology 路线

utilizing WTK良 good toward for 象虚拟 development ring 境, mold product equipment 实例, 显示设置, testing, 装载文 parts for 象, 动态生 formed for 象, for is and control and other. above function table/sheet and 里1000 more C语言函数, 20 more type formed. in Windows system VC ++ ring lower, utilizing WTK and 图形库进行 development, from relatively low control development ring 境 创建, in WTK R9 in through Wtvrm12. dll调 use 虚拟现实造 type 语言VRML2, from achieve high and ObjectARX formed development 创建. 函数调 use methods:Wtobject -type -founction -to -do. use add add true ring; use Wtse ns or -new(… 建立传感 device; use “unive rse tube/pipe true; u-niverse” in product for and device for 象. product for using/adopting CAD system 建模, will for use DXF or WTK文 parts 存储. utilizing WTK provide “viewpofnt” for 象, use setting product parameters, more 视点观察虚拟场景, utilizing 跟踪传感 device 动态改变视点.

3. WrK虚拟 ring lower VRMI and CAD集 formed

三维CAD design mold product 时, can will mold product 三维图形直接转换 formed VRML2.0格式. design need will formed mold product 各 部 separation through VRML语句 has machine in 一起, can formed mold product 交互式三维图形程序 design. in currently CAD system upper, will CAD data type is 虚拟场景, is VRML格式, achieve editor can 视化, can from 任意角 degree mold product design 效果. 并允许 design 者修改位置发生 dry 涉, 安装部位 structure meet/satisfy requirements mold parts. VRML2. 0 can mold 三维体 形状, force property can and and other, through for mold 凸, and other main/primary parts features 定义, can 进行应 force, 应变, strong/high degree and rigid degree analysis 计算, make 计算结果 can 视化. in ring in, through for value 动态显示, make design 者不断修改, design parameters, improve/increase design quality.

四, 结束语

in mold product design in application WTK虚拟现实 soft parts ring 境, 借助VRML语言进行虚拟 mold product design, is design 模式 二次 revolutionary. 当然, mold product design and manufacturing research also is stage/phase, 虚拟现实 ring and CAD system versus combined, table/sheet future mold new product design development development direction.
