'g' loads during transportation

[nandviks]

Hi All,

Does anybody know (or suggest a reference)what the 'g' loads normally are during transportation on road.

We are have problems while transporting our unit and therefore would like to analyze the structure per those 'g' loads.

Thanks

Do you man cornering, braking, or accelerating loads?

Trucks are in danger of rolling at somewhere around 0.3 g lateral acceleration. Passenger cars lose grip around 0.75 to 0.85 g.

The advisory speeds on curves, using the method in the current US MUTCD, result in lateral acceleration of ~.2 to .25g.

Many curves still have advisory speeds set using the older method, which was base on the cornering capabilities of American sedans of the 1930s, and are therefore even more conservative.

It just occurred to me that if you're carrying something faragile on a truck, you might be more interested in vertical accelerations due to bumps. Have you asked your question in one of the automotive forums?

We had to use ~4g when transporting a large pump motor

Could you please explain the basis of your calculations, ...also were they vertical or lateral acceleration ?
