I have a full tractor-trailer model. On the Tractor Steer Axle, I have single Tires, and all other Axles I have Dual Tires.
I’m running a static and then a dynamic analysis. I’m setting an initial velocity for all the parts in the model. In addition, I’m specifying an initial rotational velocity for all Tires and Wheels. In the hopes of stamping out some of the transients between the static and dynamic, I’m basing the initial rotational velocity on the actual realized Tire radii at each position after the static.
Looking at the results, I’m seeing that the single Tires at the Steer Axle start at the assigned spin velocity. However, the Tires that are part of a Dual set start at about 1/3 the assigned values and then “find” the right value after a few (~10) time steps. I’m guessing this is a “jolt” to the system causing the above-mentioned transients between static and dynamic.
So, what am I forgetting? Is there something about the dual tire setup? Something else?
