Multibody system dynamics

The Mechanical Engineering Laboratory (LIM) is specialized in the computer simulation of mobile mechanical systems, which is based on the discipline known as multibody system dynamics. Basic research in this discipline is always a line of the laboratory, since there is no method that allows all problems to be solved, but each new problem usually presents peculiarities that require new research. Thus, it is essential to contemplate the different components of the method in an integral way, since each one of them influences the others: modeling, choice of coordinates, formulation of the equations of motion, numerical integration, programming. The challenge is greater the greater the detail required in the model (flexibility of the elements, contact and impact phenomena, control, multiphysics -electricity, hydraulics, thermodynamics, etc.-) or when optimization problems are addressed.

Multibody system dynamics finds application in all those sectors that present mobile mechanical systems. The LIM focuses on practical applications in the automotive, biomechanical, machinery, and maritime fields. Computer simulation is complemented by the development of physical prototypes and experimentation when the projects so require.

Listed below are applications in which the LIM works or has worked in the sectors mentioned:

	Automotive Vehicle multibody models Observers of states, forces and parameters based on multibody models of vehicles: virtual sensors Vehicle monitoring Vehicle controllers Digital twins of vehicles or components Component test benches Simulation of real tests
	Biomechanics Complete or partial multibody models of the human body, at the skeletal, musculo-skeletal, or neuro-musculo-skeletal level Analysis of human and animal motion Exoskeleton analysis Active orthoses for gait assistance Biomechanical sensorization
	Machinery Excavator simulators Crane simulators Forklift simulators Simulators of ...
	Maritime Simulation of the behavior of fishing nets and gear in the sea Fishing net tests Simulation of maneuvers on surface ships or submarines Simulation of marine energy harnessing systems
