I am using Adams Machinery to model helical gears with 3D contact method, I am getting noise in the results when I compute forces at gear joints (revolute). Is there any way to avoid these noise in the result without application of filters.

    The surfaces of the gears is a meshed surface, which means that you cannot avoid the noise from the 3D contact. You can influence the noise by changing the mesh settings (number of profile points & number of layers).
    If you are not interested in the gear mesh error you can use the simplified gear force instead of the 3D contact. This will give you a smooth transition and still provide all resulting forces. Only the gear mesh error will be omitted.

    Hello MSC Team,
     
    I am modelling below gears with simplified contact (spur gears). I want to make gear 2 as floating gear (no bearing ). I am facing problem modelling it as floating one. I tried using bushing constraint for gear 2 (restricting axial translation and all rotation). I tried with different coupling directions bit did not work. (It works in detailed contact method with no loads on gear 2 bushing as expected).
     
    Is there any way to work with simplified contact method.

    The simplified gear contact method needs a reference part outside the gears (i.e. carrier part). It is not suited to model a floating gear.
    If you have spur gears (not helical) then you can use the Detailed gear force. This is a very accurate and fast gear force, but it is Spur Gear only. Please note that with this gear force you will need to constrain the gears in the same plane. I have not tried to use this with a floating gear, so I don't know if it will work.
    If that doesn't work, you are stuck with the 3D contact force.
     
    Please note:
