关于客户
Fallbrook Technologies Inc. 是一家位于德克萨斯州锡达帕克的技术开发公司。该公司的核心技术是获得专利的 NuVinci® 变速箱，一种无级变速行星 (CVP) 技术。该技术可以提高使用发动机、泵、电机或齿轮传动系统的机器的性能和效率。他们的产品范围包括城市机动车辆、轿车和卡车、工业设备等。 Fallbrook 利用 NuVinci 技术的独特集体开发模式和社区方法有助于加速产品开发，从而改善能源管理、提高性能、更有效、更可靠的控制和可持续的解决方案。他们最初的商业产品是用于自行车的无级变速器 (CVT)，现在包括一个基于骑手需求的产品组合，由五组套件组成。
挑战
Fallbrook Technologies Inc. 是一家技术开发公司，在改善其专利 NuVinci® 传动系统内的油流方面面临着挑战。传动系统是其产品线的重要组成部分，该产品线包括城市机动车辆、轿车和卡车、工业设备等。系统内的油流直接影响变速器的效率、耐用性、功率、容量和成本。然而，对如此复杂的传输系统的设计进行物理评估实际上是不可行的。该公司需要一种经济有效、高效且稳健的方法来提供内部润滑并预测设计方案的有效性。他们还需要一个有效的求解器/软件来指导创新过程中的设计过程。
解决方案
Fallbrook 向 Altair 寻求解决方案。 Altair 提供了集成解决方案，其中包括先进的 GPU 硬件、高性能计算 (HPC) 和 Altair nanoFluidX™ 软件。 nanoFluidX 软件是一种先进的 CFD 求解器，用于模拟 NuVinci 产品内部的润滑流动。它使用平滑粒子流体动力学 (SPH) 方法来预测具有复杂运动的复杂几何形状中的流动，例如具有旋转齿轮和轴的动力总成系统中的注油。仿真模型是使用面向过程的有限元建模软件 Altair Simlab™ 生成的。这包括系统的网格划分、材料和属性分配、所有内部零件的运动定义以及代表油的 SPH 网格的粒子生成。 Altair 的 HPC 云计算解决方案有助于减轻如此大规模模型的计算费用，而 Fallbrook 无需处理云计算系统和相关硬件的维护。

Case Study
Taking Oil and Gas Exploration to the Next Level
DownUnder GeoSolutions (DUG) wanted to increase computing performance by 5 to 10 times to improve seismic processing. The solution must build on current architecture software investments without sacrificing existing software and scale computing without scaling IT infrastructure costs.
Case Study
Remote Wellhead Monitoring
Each wellhead was equipped with various sensors and meters that needed to be monitored and controlled from a central HMI, often miles away from the assets in the field. Redundant solar and wind generators were installed at each wellhead to support the electrical needs of the pumpstations, temperature meters, cameras, and cellular modules. In addition to asset management and remote control capabilities, data logging for remote surveillance and alarm notifications was a key demand from the customer. Terra Ferma’s solution needed to be power efficient, reliable, and capable of supporting high-bandwidth data-feeds. They needed a multi-link cellular connection to a central server that sustained reliable and redundant monitoring and control of flow meters, temperature sensors, power supply, and event-logging; including video and image files. This open-standard network needed to interface with the existing SCADA and proprietary network management software.

Refinery Saves Over $700,000 with Smart Wireless
One of the largest petroleum refineries in the world is equipped to refine various types of crude oil and manufacture various grades of fuel from motor gasoline to Aviation Turbine Fuel. Due to wear and tear, eight hydrogen valves in each refinery were leaking, and each cost $1800 per ton of hydrogen vented. The plant also had leakage on nearly 30 flare control hydrocarbon valves. The refinery wanted a continuous, online monitoring system that could catch leaks early, minimize hydrogen and hydrocarbon production losses, and improve safety for maintenance.

Integral Plant Maintenance
Mercedes-Benz and his partner GAZ chose Siemens to be its maintenance partner at a new engine plant in Yaroslavl, Russia. The new plant offers a capacity to manufacture diesel engines for the Russian market, for locally produced Sprinter Classic. In addition to engines for the local market, the Yaroslavl plant will also produce spare parts. Mercedes-Benz Russia and his partner needed a service partner in order to ensure the operation of these lines in a maintenance partnership arrangement. The challenges included coordinating the entire maintenance management operation, in particular inspections, corrective and predictive maintenance activities, and the optimizing spare parts management. Siemens developed a customized maintenance solution that includes all electronic and mechanical maintenance activities (Integral Plant Maintenance).
