The Challenge
BMW Motorrad, the motorcycle division of BMW, was facing a challenge with the crankshaft model building process. The process was previously outsourced to external providers, with the average time taken for a model being between 1-2 weeks depending on the engine type. The organization required an annual estimate of new crankshaft models to be produced for budgetary decisions. However, the actual production of the models often fell short of estimates due to varying constraints on the part of the suppliers. Additionally, for any additional crankshaft models when required, the overall order processing time could be lengthy. To facilitate effective budgetary planning and decision-making, accuracy in model production forecasts with a high degree of confidence became necessary.
About The Customer
BMW Motorrad is the motorcycle division of BMW, a German multinational company manufacturing luxury automobiles and motorcycles. With the first motorcycle manufactured in 1923, their current product line includes a variety of shaft, chain, and belt-driven models designed for off-road, dual-purpose, and sports powered by a variety of engines ranging from a single cylinder, various two cylinder (parallel twin, flat twin, boxer etc.), four cylinders inline and six-cylinder inline ones.
The Solution
BMW Motorrad chose Altair as a development partner to explore alternate solutions. The initial course of action was to clone the classical approach, duplicating a previous vendor’s process and building the model without using all the SimLab features. In parallel, Altair engineers developed the same model using SimLab technology and demonstrated the process to BMW. The idea was to establish a process for automated crankshaft meshing in SimLab. With the second project, the classical process was migrated to a complete SimLab process. The semi-automated process applied by BMW Motorrad to model an engine crankshaft for structural and fatigue analysis using SimLab includes group assignment, mesh controls & surface mesh, layered elements, volume mesh & RBEs, and renumbering and group set definition.

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).

Intelligent Building Automation System and Energy Saving Solution
One of the most difficult problems facing the world is conserving energy in buildings. However, it is not easy to have a cost-effective solution to reduce energy usage in a building. One solution for saving energy is to implement an intelligent building automation system (BAS) which can be controlled according to its schedule. In Indonesia a large university with a five floor building and 22 classrooms wanted to save the amount of energy being used.
