Title: Co-Simulation: The Road to a More Precise Model

Abstract: 

FLUIDESIGN Group performed a dynamic simulation study of the complete hydraulic system for the MPG (Multi-Purpose Gantry) being operated in the London Subway.   The results indicate that a gap still exists between the virtual prototype and the actual machine.  While the machine is in operation, torsion in the structure affects the hydraulic system’s performance.

The purpose of this presentation is to understand how we can close this gap. In integrating the deformation of the static part with the dynamics of the vehicle, the engineering entity of FLUIDESIGN Group performed a study on a complete new Articulated Boom Lift design.

The numerical simulation performed by FLUIDESIGN Group and Haulotte Group intends to validate the mechanical structure and the hydraulic sizing of a new articulating boom lift kinematics. The mechanical structure and hydraulic actuation modeling allows us to understand the interaction between the two physics which govern the boom behavior. Vibratory phenomena related to bodies' flexibility and actuators' dynamics are studied via a co-simulation method with Virtual Lab Motion and AMESim software.

From inception of the project, the risks were substantial, mainly on the backward stability of the machine. The chosen methodology was to perform a co-simulation. The 1D dynamic simulation confirmed the hydraulic systems sizing, validated the components choice, and verified hydraulics and the mechanical structure stability while the 3D mechanical model confirmed the dynamic stability, calculated the loads in the connections, and validated the effects of the controls done in the dynamic simulation on the behaviors of the machine’s systems.

In each section of the co-simulation, the models were optimized in order to perform as required. The coupling of the models was then achieved and we were able to verify the operation and the controls. We tested the virtual prototype with the recommended profile. We noticed an imbalance in the pressure at the moment the boom was going down, with an amplifying effect as it was progressing. We evaluated different solutions both in the components sizing and on the operation controls. We could then manage the controls before the material prototype was built.

The first trials of the actual prototype were conclusive. Not only we achieved a gain of time in the fine-tuning of the machine, we also were able to reduce the design time significantly. The multitude of benefits by using co-simulation allows us to foresee the future perspectives of using this type of methodology. Co-simulation is a powerful tool to build numerical models closer and closer to reality.
