挑战
The challenge for Brüel & Kjær is to design industrial and measurement-grade microphones and transducers with a known and consistent error range, even over extended periods. The company must meet diverse industry sound and vibration challenges, from traffic and airport noise to car engine vibration, wind turbine noise, and production quality control. This requires designing microphones and accelerometers that adhere to various measurement standards. The goal is to achieve high precision and accuracy in their devices, which is critical for their customers, including major companies like Airbus, Boeing, Ferrari, Bosch, and NASA.
关于客户
Brüel & Kjær A/S is a leading company in the field of sound and vibration measurement and analysis, with over 40 years of experience. Their customer base includes prominent names such as Airbus, Boeing, Ferrari, Bosch, Honeywell, Caterpillar, Ford, Toyota, Volvo, Rolls-Royce, Lockheed Martin, and NASA. The company specializes in developing and producing condenser microphones and vibration transducers that cover a wide range of frequencies and sound levels. Brüel & Kjær's products are used in various industries to address sound and vibration challenges, ensuring high precision and accuracy in measurements.
解决方案
Brüel & Kjær employs simulation as a core part of their R&D process to design and test their microphones and transducers. For microphones, they use multiphysics models to analyze the movement of the diaphragm, electromechanical interactions, resonance frequency, and thermal and viscous acoustic losses. This detailed modeling helps predict interactions between the backplate and diaphragm, influencing the microphone's directional characteristics. Simulations also allow them to test different vent configurations for low-frequency sounds, enabling the exploration of new designs and device limits. For vibration transducers, simulation helps design devices that avoid resonance frequencies within the typical range of 10 to 1000 Hz. Mechanical filters are used to cut away undesired signals caused by transducer resonance. This approach allows Brüel & Kjær to quickly and efficiently test new design solutions for various operating scenarios, bringing them closer to achieving high precision and accuracy in their products.

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).
