Important parameters: flexibility and rigidity

Compensation springs work by applying a force that is proportional to the compression that they are subject to. Each part, through an ad-hoc customisation process, can have different characteristics. To correctly assess the compensation springs, it is necessary to keep certain essential parameters in mind: rigidity and flexibility.

The reference is specifically to the speed that the spring expresses increases, while the spring itself is subject to compression. Each customer can have different needs, and it is possible to intervene on this parameter. For example, if it is necessary to use a more rigid spring, it will be necessary to increase the wire gauge (reducing the spring diameter); on the other hand, if a more flexible spring is necessary, it will be necessary to do the opposite.

What sectors use compensation springs

Load compensation springs are used in sectors such as automotive, the oil and steel industries, and more. It is possible to design compensation springs by referring to a set of base materials in combination with optional treatments: naturally, all of this is in view of customisation and based on the specific use and destination of the accessory. It will first be necessary to identify the type of fatigue the spring will be subject to. Let’s see what characteristics make it possible to assess the quality and operational capacities.

Characteristics that determine spring function

We have already mentioned the importance of aspects such as rigidity and flexibility, combined with the number of waves, characteristics of forces that the spring can apply and counter. The springs that we use often require prior setting, so as to compensate for lengthwise sag – completely functional – that occurs during the work phase (the spring is compressed to the work length, so as to assess the relative sag).

Another crucial factor is the frequency of use: some supports work statically, and others are dynamic (for example, a slow combustion motor). The aspect relative to the frequency of use affects the choice of material used to manufacture it.
