挑战
Duratec 是一家以其创新的手工自行车车架而闻名的捷克公司，它面临着开发和优化轻质复合材料赛车车架的挑战。主要目标是通过最小化质量同时保持或增加刚度和强度来创建世界一流的性能自行车车架。自行车车架是可靠自行车的支柱，必须采用高强度、高模块化纤维和最好的树脂层压而成。由于需要遵守欧洲标准 EN 14781（该标准规定了性能和安全措施要求），这一挑战变得更加复杂。 Altair 在捷克共和国的渠道合作伙伴 Advanced Engineering 的计算机辅助工程 (CAE) 部门必须优化层堆叠和满足所有结构目标所需的层数。
关于客户
Duratec Ltd. 由 Milan Duchek 于 1992 年创立，是一家捷克公司，以其创新的手工自行车车架而闻名。该公司的成立是杜切克对手工自行车零件的热情的结果。 Duratec 使用铝和复合材料开发自行车车架，重点是通过提供独特的自行车参数来满足骑手的满意度，为客户提供个性化的方法。该公司的目标是开发最适合客户期望的自行车，并特别注重获得正确的尺寸、车架几何形状和优化的座椅定位。 Duratec 还参与合作活动，例如赞助四届残奥会多次金牌得主捷克残奥会赛车手 Jiri Jezek。
解决方案
为了应对这一挑战，Duratec 利用 Altair HyperWorks 套件进行三阶段优化过程。该模型是在 Altair HyperMesh 中创建的，使用 Altair OptiStruct 进行优化，并使用 Altair HyperView 评估结果。第一阶段涉及自由尺寸优化，其中定义了每个复合材料层的最佳形状和位置。第二阶段是尺寸优化，确定层片的最佳厚度。最后阶段是随机优化，评估复合层可能的堆叠顺序，并提出满足所需设计特性的理想顺序。 Duratec 还使用了一种独特的制造技术 OnePiece 技术 - 100% 硬壳式结构，该技术允许在一次热处理中将整个框架（包括管连接）作为一个整体生产。该技术确保了最高的制造精度和最高的加工质量。

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

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.
