What is a road simulator?

The road simulator is a system formed of: test device, hydraulic actuators, dynamic controllers, data acquisition hardware and playback commanded by a computer program that simulates the road conditions in a lab.

These programs are used to perform durability tests on components and mechanical subsystems, especially automotive and with hydraulic actuators. The simulator allows tests to represent more precisely the possible failures that may appear when the product is used.

During the first stage the vehicle or subsystem is instrumented and it's data is collected while it performs on the actual test course we want to simulate.

During the second stage, the vehicle or subsystem is installed on the lab test device and the transfer function of the system is calculated.

During the third stage the road drive of each course we want to simulate is determined.

This road drive is obtained through iterations that calculate the signals that must be applied on setpoint inputs of the controllers so we can obtain the response of the installed sensors on the vehicle, the same way as in step one.With the drive signals of each road in hand we proceed to the fourth and final stage: we structure a sequence of repetitions of the signals of the road drives to determine the procedure of the durability test.
