挑战
Cobra Aero, a US-based manufacturer of UAV drone engines, faced the challenge of staying competitive in the market. They invested in a Direct Metal Laser Sintering (DMLS) system to redesign key parts of their engine for Additive Manufacturing. The team aimed to achieve multiple advantages, including improved efficiency, weight requirements, and minimal support during manufacturing. They sought alternatives to traditional fin designs for heat transfer and became intrigued by lattice structures used in heat exchanger design. The challenge was to optimize the lattice structure for heat transfer while meeting the performance and manufacturing requirements.
解决方案
Cobra Aero used nTopology's advanced modeling capabilities to generate different sizes of lattices with varying strut thickness. They filled the lattice inside their cylinder geometry and terminated it with smooth transitions and fillets between the struts. To optimize the lattice for heat transfer, they used nTopology's field-driven design capabilities to spatially control the properties of the lattice. They utilized multiphysics simulation results, including temperature, airflow velocity, pressure drop, and mechanical stresses, to generate a highly optimized structure. The lattice structure was tightened in areas where conduction was more important and loosened in areas where convection was more important. Once the design was finalized, they used nTopology's slicing capabilities to export a CLI file that was sent directly to the Renishaw AM500 system for manufacturing. Testing showed that the new lattice structure design was more efficient than the fin design, requiring less airflow to maintain proper engine temperature in every loading case and at every RPM.

Case Study
Improving Vending Machine Profitability with the Internet of Things (IoT)
The vending industry is undergoing a sea change, taking advantage of new technologies to go beyond just delivering snacks to creating a new retail location. Intelligent vending machines can be found in many public locations as well as company facilities, selling different types of goods and services, including even computer accessories, gold bars, tickets, and office supplies. With increasing sophistication, they may also provide time- and location-based data pertaining to sales, inventory, and customer preferences. But at the end of the day, vending machine operators know greater profitability is driven by higher sales and lower operating costs.

Case Study
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).
