What is the maximum impact force on a conveyor belt during a test?

[PeterB]

Hi good people,

I have some problem with determining impact force acting on rubber-like elastic material (conveyor belt).
The problem is:
The object of mass M is released from the height H on conveyor belt which is clamped at the both ends and subjected to an uniaxial tensile force T. I would like to determine the maximum impact force (not impact energy) acting to the belt conveyor during the impact test if I know the acceleration-time curve. The acceleration changes during impact in a very small time interval. Can I use the formula IMPACT FORCE = MASS(it is constant) x CHANGE IN ACCELERATION ? CHANGE IN ACCELERATION (DECCELERATION respectively) is as follows: Acceleration before impact (9.81 m/sec^2) - Acceleration if object of mass M is in the lowest position.
And how can I calculate the maximum displacement of the object if given are Poisson's ratio and Modulus of elasticity of conveyor belt. Can anyone give answer for this problem.
Thanks

Hello,

I understand the importance of accurately determining impact force on materials. In order to calculate the maximum impact force on the conveyor belt, we can use the formula you mentioned: IMPACT FORCE = MASS x CHANGE IN ACCELERATION. However, we must also take into account the time interval over which the acceleration changes, as this can greatly affect the impact force.

To calculate the maximum displacement of the object, we can use the equation: Displacement = (Force x Length) / (Poisson's ratio x Modulus of elasticity). This will give us the maximum displacement of the object on the conveyor belt.

Additionally, it may be helpful to consider the material properties of the conveyor belt itself, such as its thickness and strength, in order to accurately determine the impact force and displacement. I would also recommend consulting with a materials engineer for further assistance with this problem.

I hope this helps and good luck with your research!
