关于客户
本案例研究中没有明确提及客户。但可以推断，客户是从事复合材料设计和制造的公司。其中可能包括航空航天、汽车和其他行业的公司，其产品需要复杂的复合材料。这些公司需要准确地表示和模拟复合材料的行为，生成真实的缠绕零件有限元模型，执行包括较小规模的精细区域的全局模拟，并模拟复杂复合材料零件的叠层制造过程以预测纤维的取向和纤维体积分数。
挑战
该案例研究提出了公司在复合材料设计和制造领域面临的几个挑战。第一个挑战是准确地表示复合材料的行为并从多种可能性中选择最佳选择。第二个挑战是生成伤口部件的真实有限元模型。第三个挑战是执行全局模拟，其中包括较小规模的精细区域。第四个挑战是模拟复杂复合材料零件的叠层制造过程，以预测其纤维的取向和纤维体积分数。最后的挑战是模拟航空天线罩的叠层制造过程，预测其纤维的方向，并在预测电磁性能时考虑这些方向。
解决方案
CEDREM 的 KTex 系列软件为这些挑战提供了解决方案。对于第一个挑战，KTex Pattern 用于表示纱线尺度的复合材料，KTex WovenProperty 用于计算任何给定组织的均质宏观机械性能。对于第二个挑战，KTex Winding 用于可视化纱线在卷绕过程中所遵循的路径，并考虑纱线的机械性能来模拟卷绕过程。对于第三个挑战，KTex Pattern 和 KTex LayUp 用于在纱线尺度上精确模拟复合材料，在选定区域细化复合材料，并将更新的机械性能从较低尺度模型集成到高尺度全球模拟。对于第四和第五个挑战，KTex Pattern 用于在 HyperMesh 内构建多种织物的细观有限元模型，KTex Layup 用于在 HyperMesh 内建立制造过程模拟并使用 RADIOSS 求解器运行。

Plastic Spoons Case study: Injection Moulding
In order to meet customer expectations by supplying a wide variety of packaging units, from 36 to 1000 spoons per package, a new production and packaging line needed to be built. DeSter wanted to achieve higher production capacity, lower cycle time and a high degree of operator friendliness with this new production line.

Boiler Control System for Plastic Manufacturing Applications
Factory automation applications must be equipped to handle and monitor the myriads of information from attached devices. For plastic manufacturing applications, the boiler control system plays a critical role by gathering and regulating information to ensure production is accurate and smooth. In this particular case, the customer combines eight subsystems that include power meters, water meters, alarm output, displays, and I/O status to be controlled by several intelligent controllers with Modbus RTU interface. The Modbus TCP protocol is used for this application due to the distance. System Requirements: • Modbus serial to Modbus TCP translation • Multiple slaves/masters support • Automatic Modbus TCP response time detection
Case Study
Ascend Performance Materials Case Study
Ascend operations must access multiple software systems to manage day-to-day operations in an effective and secure manner. These systems generate large sets of data which contain critical information pertaining to management systems, planning and cost information in business systems and energy consumption. As a result, Ascend management was challenged with creating relevant reports reflecting performance measures in overall context of their operational process. The company’s previous process entailed collecting and analyzing data manually which was not effective, since the information collected was generated after the fact, and was too complex for collaborative use across the organization.

Corporate Identity Solution Adds Convenience to Beckman Coulter
Beckman Coulter wanted to implement a single factor solution for physical and remote logical access to corporate network. Bechman Coulter's users were carrying smart card badges for doors, but also needed a one-time password token to access to our corporate network when they were not in the office. They wanted to simplify the process.
Case Study
Remake Enterprise-to-production System
The client was running a legacy material flow tracking system and wanted to replace the system with a more effective one as the system was increasingly expensive to maintain and support and also was not extendable. The client's IT landscape was filled with modern applications and it was difficult to interface the material flow tracking system with modern applications.
