Multibody system dynamics
The Laboratory of Mechanical Engineering has specialized on multibody system dynamics. Basic research on this discipline is always required in the lab, since there does not exist a single method to address optimally all the problems in this area of knowledge. New problems often feature peculiarities which demand new research to be carried out. It is then essential to holistically consider the various components of the method, as each of them affects the others: modeling, coordinates selection, formulation of the equations of motion, numerical integration, and programming. The challenge increases with the required level of detail in the model (flexible bodies, contact and impact phenomena, control, multiphysics -electricity, hydraulics, thermodynamics, etc.-) or when addressing optimization problems.
The research lines of the lab that result from the application of multibody system dynamics to various fields are described next.

Automotive
We are working on the development of state/input observers based on multibody models of cars which may serve as virtual sensors, and on their implementation in on-board embedded systems. We are also developing multibody models of cars to be used in hardware-in-the-loop simulation. In the past, we developed a car driving simulator too.

Biomechanics
We are working on the development of active orthoses to assist the gait of SCI subjects, and on methods for gait analysis and prediction which may give support to orthosis design and patient adaptation.

Maritime
We are working on the simulation of fishing nets and tackles, and on test methods to characterize net opening resistance. We are also working on the validation of a software package, previously developed in the lab, for the simulation of the lifting maneuver of ship anchors. In the past, we simulated wave energy converters, and the launch and recovery of autonomous underwater vehicles from submarines.

Machinery
These applications are usually addressed upon requests from companies. We have developed several simulators: excavator, cranes, forklift, etc.
