Multibody simulation is the best technology to analyze the dynamic behavior of safety circuit breakers. These mechanisms are characterized by high-speed dynamic motion: to prevent damage, the switch from the “on” position to the “off” position must occur in just a few milliseconds.
The premium software RecurDyn was used to simulate a Double Pole Single Throw Switch using three different modeling schemes: the first model used rigid bodies and joints; in the second model, the joints were replaced with contacts; and in the third, the main components of the switch were modelled using flexible bodies. A comparison of the results highlighted the influence that clearances (in the second model) and flexibilities (in the third model) had on the commutation time and the commutation force, which provided useful information for the designers.

The text provides an in-depth account of Stefano Odorizzi’s journey in founding and growing EnginSoft, our engineering company specializing in computer simulation and modelling. Established in 1984, EnginSoft overcame early challenges, such as the high cost of computing, to emerge as a leader in simulation services, particularly in the fields of mechanical engineering and computational fluid dynamics (CFD). The narrative highlights several key milestones in the company’s history.

In this example, a tracked bulldozer was simulated to evaluate the dynamic behavior of the vehicle on different terrains and with different obstacles. The model can also be used to calculate the loads operating on the vehicle’s structure..
