Study of static cushioning properties: Automated data input and reliability test of static cushioning properties

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.     

Study of static cushioning properties and construction of a database for static cushioning properties

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.

Support tool for material and process combinations during early design

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.     

State Behavior Database for Pure Liquids and Data Correlation

A database system designed for storage, maintenance, and evaluation of published experimental data related to the state behavior of pure liquids is described. The database system is maintained by a program package (FoxPro) that allows the effective and user-friendly process to enter, store, handle, and update the information starting from a bibliography and ending in a data evaluation. Evaluation of data is performed using either two functions of temperature for data at 0.1MPa or at saturation or the Tait equation for density data at elevated pressures. The weighted least-squares method is employed to evaluate the adjustable parameters of smoothing functions. Search and export program modules allow various views, searches, and outputs of the content of the databases. At present, the database system contains about 4,400 records in the bibliographic part, more than 100,000 experimental data points for about 500 substances, and over 800 sets of parameters of smoothing functions for about 330 substances. The database system is intended as an effective tool for compilation and critical evaluation of data, not as a commercial databank for distribution.     

Rapid Evaluation of Prediction Methods with DIPPR’s Automated Property Prediction Package

An automated property prediction package has been developed that permits rapid evaluation of group-contribution, corresponding states, empirical, and theoretical property estimation methods. The property prediction package, which is part of the DIPPR^® Information And Data Evaluation Manager (DIADEM) software, is used in conjunction with the DIPPR^® 801 database to develop and test new prediction methods. The software is freely available to all DIPPR sponsor companies, but is also commercially available. The estimation engine is based on an automated SMILES (Simplified Molecular Input Line Entry Specification) formula parser to provide required molecular structural information, retrieval of required secondary properties from the DIPPR^® database, and defined rules for the method. Automatic comparisons of predicted values to experimental data in the DIPPR^® database can be made for properties at specified accuracy levels, by chemical family or type, or over the entire database. This allows evaluation of the relative effectiveness of methods for specific chemical families and tailoring of the selected method to specific chemical classes. New methods can readily be added by input using a simple input form. Nearly 200 thermophysical property prediction methods are currently available in DIADEM.     

Thermodynamic Assessment and Experimental Investigation of Fe-Al-C System

Phase diagram information of the Fe-C, Fe-Al and Al-C systems are reviewed and the Fe-Al-C system is assessed. A FeAlC database is created by combining a set of thermodynamic parameters established by Kumar and SSOL database in Thermo-Calc software package. Ternary phase diagrams are calculated with FeAIC and the newly developed Thermo-Calc databases SSOL2 and SSOL4. The FeAIC database is the best one to describe the Fe-Al-C system. Al and A3 values on the vertical section containing 1.5 wt pct AI are calculated with the FeAIC database in this work. To validate the thermodynamic calculation, critical temperatures Ac1 and Ac3 are determined by using dilatometer analysis. There exist some errors between the calculated values and the experimental results. So further optimization of the Fe-Al-C system regarding bcc and fcc phases is necessary. The experimental data in this work could be of some value in further optimization.
