does anyone know how to determine how much force the tounge of a trailer has in solid works. I have designed a trailer and i belive i have my axle in the right location now i want to know how much tounge weight I have, can anyone help.
Use SW to check where the CG is of your trailer and any load on it. If the CG is in front of the axle centerline, then the force on the tongue will be the percentage of that load that the CG is in front of the axle vs. the distance from the axle to the hitch ball. For example, if the distance from the ball to the axle is 50" and the CG is 10" in front of the axle, and the mass of the trailer is 1000#, then the tongue load will be (10/50)*1000, which is 200#.
You can also use Cosmos or Cosmos express to show these forces as well and where the weak areas lie.
^ What Wayne said.
But why stop there? If you are designing your own trailer, make sure you are taking into account what you are designing the trailer for and how you anticipate to haul that load.
A small trailer designed for say 2 quads COULD be a much different configuration than a general prupose trailer.
Design for your worse case scenario and that typically leaves you with plenty to work with.
