Lump mass(zero element) simulation

[shantidass]

Hi,

I want ask whether it is possible to use Lump mass method to do force analysis simulation, this is for my client payload model. My client suggest to create a lump mass (0D element) to represent payload( due it be complicated) and then link that element to platform attachment points via rigid links/connections. They say that it will make simulation work more easier and faster.

However, I don't know whether this is even a viable method to do simulation with in fusion 360 because i have never done it before . So i want to check if this is method is even possible and is there such thing as exporting model in lump mass format.

Hello and welcome to the forum!

@henderh do you have any insights on this?

Hi @shantidass,

I believe a Remote Force load can fulfill the requirement. It can be used to represent a load from complex geometry, or geometry that isn't included in the model. It uses rigid links to transfer the load (force and implicit moment) to the selected faces of the modeled geometry.

• Remote force loads in the Simulation workspace

If you're only interested in the effects of weight from the complex geometry or geometry not included in the model, the analysis can be simplified by representing it using a point mass.

• Point mass

Neither of these methods require creating Rigid Body Connectors manually. The Rigid Body Connectors are added automatically in a Remote Force. In a Point Mass, the loads from the weight are applied directly to the selected faces.

Hi Hugh Henderson,

Thanks for the solutions and advice, but i just want to check whether my client suggestion and the idea of creating zero element model to joint to payload load in fusion is viable or not. I don't need really a solutions but i thank you for it. I just need whether it possible or not.
