b'Heavy Industries | Engineer InnovationAvoiding recurrent prototyping to reduce risk For heavy equipment manufacturers, customer requirements are usually so diverse and at the same time so specific that most machines are a limited series, if not unique editions. As a result there are lengthy development cycles that include a lot of trial-and-error and recurrent prototyping. Consequently, early virtual validation of various design aspects, including the machine concept and control strategies, is critical to save time and reduce risk. As well as this the development of information processing by the Controller Area Network (CAN) bus benefits enormously from such a simulation-based approach. This is what French-based, Cerebrum-Ingnierie, has turned their focus to. Founded in 2015 from the Fluid Design Group, Cerebrum-Ingnierie engineers help manufacturers, particularly in the heavy equipment industry, to optimize and secure the development of mechatronic systems by bringing digital modeling into the design process. For this, they use Simcenter Amesim software from Siemens Digital Industries Software.The first CAN bus was developed at Robert Bosch GmbH in the 1980s, as a response to the continuously growing number of distributed signals and interfaces in car passenger vehicles. The multiplexing of these systems had to be generalized and standardized. As todays requirements regarding energy efficiency, emissions, safety and comfort have led to an exponential increase of smart sensors and actuators, the CAN bus is becoming more complex, while at the same time more important than ever. The development time of algorithms inside the bus is largely determined by the required validation and fine-tuning calibration of the machine in operation.79'
