snow plows

snow plows

Hi. I Need to find some information on how snow plows affect the CG of vehicles, as well as the forces and stress analysis of plows on a truck.

Thank you.

Eng. in snow land.

RE: snow plows

These should be questions to the manufacturers of the plows themselves.
These questions were hopefully asked during the the design stages in order to make a quality product.

RE: snow plows

I'd bet you won't find much if you look larger than light duty trucks.

Medium and heavy duty users / manufacturers tend to build it larger each time it breaks as use is incredibly hard to predict.

The loading on plows varries by operator skill / attitude.  Some operators need to wear a seatbelt to keep them in their seat!

For light trucks this means a weak point is designed into the plow.  Meyers have an offset tab which shears when overloaded.  I broke them both off my personal plow last year hitting an ice bank at low speed.

Trip style also affects the dynamic loading.  An edge trip will almost always dump and ride up when overloaded.  A moldboard trip will only dump if the upper part of the moldboard is clear to tip.

As far as cog, a 6.5 ft blade and push frame weighs about 150 - 250 lbs, the bracketry and pump on the truck about 100 - 200 lb.  The blade is hung about 2 ft in front of the truck whereas the bracketry is next to the front of the truck.

Hope this helps.

RE: snow plows


Here are some resources I am aware of regarding snow plow loads:

Olson, WW, A Kempainen, M. Milicic and Mark Osborne, “Dynamic Modeling of Forces on Snowplow Equipped Trucks,” SAE Paper 973193, in Heavy Vehicles and Highway Dynamics, SAE Special Publication 1308., 1997, Pg. 49 - 55. Available from www.sae.org.

Kempainen A., D. Milacic, M. D. Osborne, W.W. Olson, “Modeling and Testing Snow Ploughing Forces on Trucks,” International Journal of Vehicle Design, Vol 19, No4, 1998. Pgs 472-503. www.inderscience.com/catalogue/v/ijvd/ijvd.html
