Multiaxis vibrations

Environne'Tech has a facility for controlling up to 6 axes for simultaneous management of up to 6 vibrators (electrodynamic or electrohydraulic). Control is sine, random, or repeats road signals, and force, displacement or acceleration signals.
For example: stresses along 3 directions are measured at a point of an axle system element mounted on a vehicle driving on a roadway.

The axle system gear element is then set up on a bench with 4 hydraulic jacks that exert force at several points of the structure. The jack control signals can be calculated by successive iterations to generate the forces measured on the roadway.
