Circuit Breakers

Multibody simulation is the best technology to analyze the dynamic behavior of safety circuit breakers

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.

Improving the performance of shaped charges and passive ballistic protections

CAE models evaluated using two commercial solvers

In this technical article, the authors discuss the development of CAE models for simulating the behavior of shaped charges, devices used in various industrial sectors, against two types of target – a monolithic steel target and a multi-layer steel-ceramic target – in order to better understand the physics of penetration.
