包装件或产品的共振频率、振动传输比、阻尼等因素组成了包装系统的动态特性,它是由包装材料与整体包装系统共同决定的。包装系统的动态特性能够反映出在一定的运输环境(冲击、振动)下,包装对产品的保护能力。因此在进行包装设计时,经常需要测试包装件或产品的共振频率,根据共振点来设计包装系统,避免包装件在实际运输过程中发生共振现象。 相似文献

目的研究动态回收环境下,如何确定使利润最大化的废弃包装回收量和回收价格,以及RL-MIS在废旧包装回收过程中的优化问题。方法以RL-MIS为基础,从动态规划(DP)的角度研究回收量、回收价格与各参数之间的关系,构建新的废旧包装动态回收过程DP模型;根据Database提供的历史数据求得供给曲线方程作为验证方程,检验该动态回收模型的运行结果。结果算例结果得到某种材料的废旧包装的每日最佳回收量为263.7 t,最佳回收价格为590.8元/t。结论结合动态模拟结果,表明该模型可在动态回收环境下模拟获得废旧包装回收量与回收价格的最佳解集。说明合理运用该DP模型可以有效提高废旧包装回收收益,并降低回收成本。 相似文献

The aim of this research is to develop an Expert System (ES) that is linked into a 3D design package, which will provide comparison data for various material and manufacturing process combinations to produce a design. The early design stage is the optimum time to ensure that the material and manufacturing process chosen will realize a design's requirements. This paper focuses on the steps within the process to create the Expert System and provides an example of its use. The CAD package chosen is AutoCAD 2004. A recognition module has been developed to recognize a 3D model and to segregate the model into that of the quadratic and polyhedron primitives within a database. A generic material and manufacturing database has been designed. This has established a basic platform from which the different material and manufacturing processes can be compared. As each manufacturing process has process-specific rules, it is necessary to examine the 3D model for the suitability of the processing method chosen within the ES. This ES aims to increase the knowledge available to the designer to aid in the decision-making process, through the comparison reports generated and the web link and specific documentation facility within the software package. 相似文献

In this paper, we identify and propose solutions for several issues encountered when designing a mesh adaptation package, such as mesh‐to‐mesh projections and mesh database design, and we describe an algorithm to integrate a mesh adaptation procedure in a physics solver. The open‐source MAdLib package is presented as an example of such a mesh adaptation library. A new technique combining global node repositioning and mesh optimization in order to perform arbitrarily large deformations is also proposed. We then present several test cases to evaluate the performances of the proposed techniques and to show their applicability to fluid–structure interaction problems with arbitrarily large deformations.

The rapid advance of computerization in industrial package design has led to a strong tendency toward CAD/CAM systems using personal computers for quick design and trial manufacturing. New tools based on a database of the cushioning properties of packaging materials will be needed for the design of package cushioning. Using a compression testing machine with computer control, an attempt has been made to construct such a database with registered characteristics for 47 samples of foamed polyethylene, foamed polypropylene and foamed polyethylene-polystyrene. This database offers the following functions and is recorded on floppy disk: (i) calculation of static cushioning properties (value); (ii) print-out of the computed results; (iii) drawing characteristic figures for designing package cushioning; (iv) indicating optimum value of static cushioning properties; (v) additional registration of new samples. 相似文献

A computer-controlled compression testing machine is used to compile a database of the static cushioning properties of package cushioning materials. Through research into automated data input procedures, so far not developed, a direct transfer program (ZABCON) has been devised, which allows direct access to the disk in which compression test data are stored. Elimination of manual data input has led to simplified and easy construction of a database, and the applied laboratory tests, such as that for determining the relationship between static cushioning properties and compression rate, can be performed quite readily. Also in this report, the application of the static cushioning characteristics of foamed polystyrene in the cushioning package design of dummy goods and the evaluation of its reliability by drop testing are discussed. 相似文献
