Simulation of a suspension with SimMechanics and SimHydraulics
Simulation of a suspension with SimMechanics and SimHydraulics
(OP)
In the Simulink environment its possible to create a multi-body model for simulation a simple vehicle model. This is an option for simulating with a simple spring and damper. Now I want to simulate a hydro pneumatic suspension with SimHydraulics connected to the multi-body model of SimMechanics. Separately the models work perfect, but when connected together the solver gives problems. It is an option to solve the SimHydraulics model with a local solver. But even with a local solver applied the model is stuck.
Now is my question:
Is it possible to connect a SimHydraulics model to a SimMechanics model? Both are a Simscape toolboxes.

When simulating something like you have described most of the time I derive the coupled model manually then solve the differential equation using Simulink or m-code.
Although, I know it is much faster using built in toolboxes ect. I have nothing against them.
Have you looked into MapleSim?
It can do exactly what you described in minutes. (No equations ect. )
It is helpful modeling very complex systems very quickly.

The problem is that this is meant to be a modular solution. When changing the car specifications, will the suspension remain the same. Simulating the suspension in Simulink works fine. But its a time consuming activity. The model will act as a tool to specify the desired damping.
I'll have a look into mapleSim, but I haven't got any experience with it.

It is possible to connect the 2. A stuck model is usually a physical problem or singularity.
