Elimination OF Abrupt Mechanical Shock Loading

In summary, the conversation revolved around the problem of reducing an abrupt shock load as an 850 kg machine moves down ramps and comes to a halt at the end of its tether attached to a van's tow hitch. The suggestion of using block-and-tackles for a safer descent was brought up, but it was mentioned that it may not be possible to accurately calculate the necessary spring due to unknown circumstances. The conversation was then closed due to the topic being considered too dangerous to discuss.

It's a problem of reducing an abrupt shock load as an 850 kg runaway machine trundles down ramps, and comes to an abrupt halt at the end of its tether fixed to a van's tow hitch. Ramps fixed to the van's rear door sill incline at 20 degrees to ground level and their length is 2.5 metres. I need to pass on figures to size a suitable in-line spring.

Why not use block-and-tackles to lower it gently? That sound much safer.

If we give you a spring calculation, it might be wrong because we can't know all the circumstances no matter how much you describe it.

We don't allow discussion of dangerous topics here on PF.

This is not an existing current risk which has been resolved with a valid working tether used as a backup to a self propelled machine that is successfully being driven down ramps under its own power. I am trying to improve the tether---should on the unlikely off chance it be needed--- by reducing its shock load with a suitable spring. There are no further circumstances to describe? It is a straight forward 850kg mass down a 20 degree incline requiring buffering on a tether. (KISS)

Sorry, it involves the safety of people and equipment, so we can't really offer you advice on your project. Thread is closed.
 

1. What is elimination of abrupt mechanical shock loading?

The elimination of abrupt mechanical shock loading refers to the process of minimizing or removing sudden and intense forces applied to a system or structure. These forces can be caused by impacts, drops, or sudden changes in velocity, and can lead to damage or failure of the system.

2. Why is it important to eliminate abrupt mechanical shock loading?

Abrupt mechanical shock loading can cause significant damage to sensitive equipment or structures, leading to costly repairs and downtime. It can also pose a safety risk to individuals working near the affected area. Therefore, it is crucial to eliminate these shock loads to ensure the longevity and reliability of the system.

3. What are some common methods for eliminating abrupt mechanical shock loading?

There are several methods for eliminating abrupt mechanical shock loading, including using shock-absorbing materials, incorporating shock mounts or isolators, and designing structures to better withstand shock loads. Other approaches include implementing proper handling and transportation procedures and conducting regular maintenance and inspections.

4. Can eliminating abrupt mechanical shock loading be achieved in all systems?

While it is possible to minimize or eliminate abrupt mechanical shock loading in most systems, it may not be feasible in some cases. In systems where shock loads are inevitable, such as in heavy machinery or vehicles, the focus may be on designing the system to withstand these forces rather than eliminating them entirely.

5. How does eliminating abrupt mechanical shock loading affect the overall performance of a system?

Eliminating abrupt mechanical shock loading can have a positive impact on the overall performance of a system. By reducing the risk of damage and failure, the system can operate more reliably and efficiently. It can also improve safety for individuals working with or near the system. However, it is essential to carefully consider the trade-offs and potential costs of implementing shock elimination methods.
