![]() It is possible that higher shock loads should be assumed for rail transport outside Europe. The design, dimensions and the connections between the individual packaging elements must be adequate to absorb these shock loads. This formula takes into account the kinetic energy of the impact, which is determined by the velocity of the impact, as well as the. Where IGF is the number of G forces experienced, v is the velocity of impact, and d is the distance traveled during impact. This must be taken into consideration in particular when securing the goods within the packages. The formula used to calculate the impact G force is given as: IGF 1/2v2 / d / 9.81. In the case of rail transport, figures from Deutsche Bahn show that acceleration forces of 4 g can be caused during hump shunting. This in turn has an impact on the friction acting between the package and the loading area and, if the packages are stacked, on the dimensioning of the load-bearing components of the boxes/crates. On Earth, the acceleration of gravity generally has a value of 9.806 m/s2 or 32.1740 f/s2. Gravity is measured in metres per second squared, or m/s2. It’s what keeps our feet firmly planted on the ground. This means that the package fluctuates between being heavier and lighter. 1G is the acceleration we feel due to the force of gravity. This page provides a technical overview of how to calculate the force a vaulter experiences during a fall, including an introduction to g-force calculations. This results in a change in the force exerted by the weight of the package: The values given above must be combined with the downward force of gravity of 1 g and any dynamic fluctuations (vertical) as follows: (a) = ± 0.3 gĪ package with a mass of 1,000 kg is subject to an acceleration force of ± 0.8 g additional to the force of gravity, for instance as a result of pitching of the ship. Primarily ferry traffic and container feeder services ![]() Wagons with containers, swap-bodies, semi-trailers and trucks and also "block trains" Force Calculator The force can be calculated by using the following formula: where p is the momentum, t is the time, m is the mass and a is the acceleration.
