Narrative:

As we were accelerating down runway 31L at dfw, our nose gear bottomed out at least twice. The runway has a large dip, it is followed by a rise and another dip approximately 2000 ft down the runway. I almost lost control of the nosewheel tiller. Dangerous. After liftoff, I advised the tower and tower advised us that he was aware of the dip. Not accepting that runway will be what I will do in the future. More delays! Safety first. Pleas notify dfw again.
