Issue with hair in both viewport and render I need to do a render video about some industrial brushes and their function

But , When I play the viewport animation the bristles start vibrating and then totally detach from the brush itself (you can see it here https://gph.is/g/4zArbRv), and I'm having another issue. Blender crashes when i try to render it.
Does anyone has any suggestion on how to solve this issue?
For some reason I'll leave to experts to explain, if you Apply the Array modifier on each circle array, the particle system behaves:

However, if you want each circle array member to behave independently,  you'll have to depart from array and instead Duplicate instead of array.  And if you Dip-linked, the bristles might not behave independently if an effector causes some to deform.
There may be other more expert solutions if you search on &quot;Particle System Array&quot; in this forum.
