Measures applied using the APTA method (advanced transfer path analysis) in La Rochelle.

The work done includes:

ATPA Measures: to obtain the overall structural contributions of the union points of two bogies, and the structural and aerial contributions of interior panels, 7 receiver microphones are placed in 10 dynamic conditions (30, 40, 50, 60, 70 km/h, and 2 directions of movement).

This allows us to measure the precise mobility of the union points of each bogie on a passenger car.
