How to create a solid object with only mass size and no other properties in abaqus

[Alex_920123]

The structural beam contains heavy objects, and the objects do not affect the structural strength Young's modulus, and the vibration analysis of the objects contained in the structural beam is discussed. The analysis result should be that the frequency drops and the result that I use the coupling method to give a little mass is wron

g. Is there any better way

 

[FEA way]

There are several ways to do it. From what I understand, now you are using point mass and you’re not happy with the results. Then you could use nonstructural mass feature or simply model the parts as rigid bodies.
