LMS Imagine.Lab Power Steering provides reliable and accurate models to design robust power steering systems (stability, vibration, couplings analysis) while reducing time-to-market. The solution involves different AMESim tools and libraries focusing on the reality of the multi-domain approach which is required when dealing with hydraulic, electro-hydraulic and electric power steering systems.

LMS Imagine.Lab Power Steering focuses on functional design (mainly stability or vibration issues) and enables engineers to examine functionalities and performances of any power steering system to assess technology risks and examine related electronic control units.

Detailed views of the rotary valve, pump, and hydraulic circuit can be generated for more in-depth studies as well as for analysis of vibrations and stability in parking maneuvers or driving conditions. It is even possible to analyze the shimmy phenomenon and display its contributions on the steering system through interfaces with multi-body software like LMS Virtual.Lab Motion or MSC.ADAMS.

LMS Imagine.Lab Power Steering will significantly help to define optimal steering performance, present trade-offs between technologies, identify the optimal steering feel and assess the impact of driver assistance on the driver’s perception.
