Axle weights on vehicle model/assembly

By Tony Kuiper on 30 Apr 23:55 1 answer 1 comment

Hi there...

I am working up an assembly for a vehicle which has limits on the allowable axle weights for legality and roadworthiness.

I have a mass sensor and centre of mass working, with alarms for going over a target amount of gross mass.

Currently I am calculating the axle weights by measuring the distance from the centre of mass and applying a ratio of this weight to the axle based on the distance from the centre mass and the wheelbase of the vehicle.

I would like to know if its possible to create a mass sensor at the front and rear axle which shows the weight as a function of the distance the axle is from the centre mass.

A formula might be (for example)
FrontAxleWeight = GrossMass * (1-(FrontAxleDistanceFromGrossMass/WheelBaseTotal))

I can measure this distance in the assembly but the measurement itself doesnt stay there and change as the weight changes. Havent figured if this is possible.

Thanks

Tony

    you could try to to use that dimension as a global variable (in equations)
