Why Ceetak makes use of Finite Element Analysis

Finite Element Analysis offers information to predict how a seal product will perform under certain conditions and may help identify areas the place the design may be improved with out having to check a number of prototypes.
Here we clarify how our engineers use FEA to design optimum sealing solutions for our buyer applications.
Why can we use Finite Element Analysis (FEA)?
Our engineers encounter many important sealing purposes with complicating influences. Envelope dimension, housing limitations, shaft speeds, pressure/temperature scores and chemical media are all application parameters that we must consider when designing a seal.
In isolation, the influence of those utility parameters within reason straightforward to foretell when designing a sealing solution. However, if you compound a number of these factors (whilst typically pushing a few of them to their upper restrict when sealing) it is crucial to foretell what goes to happen in real application situations. Using FEA as a software, our engineers can confidently design and then manufacture robust, reliable, and cost-effective engineered sealing options for our customers.
Finite Element Analysis (FEA) permits us to understand and quantify the consequences of real-world conditions on a seal part or meeting. It can be used to establish potential causes the place sub-optimal sealing performance has been observed and may also be used to information the design of surrounding components; particularly for products such as diaphragms and boots where contact with adjacent parts may have to be avoided.
The software additionally permits force knowledge to be extracted so that compressive forces for static seals, and friction forces for dynamic seals could be precisely predicted to assist customers within the final design of their products.
How can we use FEA?
Starting with a 2D or 3D mannequin of the initial design idea, we apply the boundary circumstances and constraints provided by a customer; these can include pressure, pressure, temperatures, and any applied displacements. A suitable finite element mesh is overlaid onto the seal design. เกจไนโตรเจนsumo ensures that the areas of most curiosity return accurate outcomes. We can use larger mesh sizes in areas with much less relevance (or decrease levels of displacement) to minimise the computing time required to unravel the model.
Material properties are then assigned to the seal and hardware parts. Most sealing supplies are non-linear; the amount they deflect underneath a rise in pressure varies depending on how massive that pressure is. This is in contrast to the straight-line relationship for many metals and inflexible plastics. ร้านซ่อมเครื่องวัดความดันโลหิต complicates the material model and extends the processing time, but we use in-house tensile take a look at services to precisely produce the stress-strain materials models for our compounds to make sure the analysis is as representative of real-world performance as potential.
What happens with the FEA data?
The analysis itself can take minutes or hours, relying on the complexity of the part and the range of working circumstances being modelled. Behind the scenes within the software, many hundreds of thousands of differential equations are being solved.
The outcomes are analysed by our skilled seal designers to determine areas the place the design may be optimised to match the precise necessities of the appliance. Examples of these necessities might include sealing at very low temperatures, a must minimise friction levels with a dynamic seal or the seal may have to resist high pressures without extruding; whatever sealing system properties are most necessary to the customer and the application.
Results for the finalised proposal may be introduced to the client as force/temperature/stress/time dashboards, numerical data and animations exhibiting how a seal performs all through the analysis. This information can be utilized as validation data in the customer’s system design course of.
An instance of FEA
Faced with very tight packaging constraints, this customer requested a diaphragm component for a valve software. By using FEA, we had been in a position to optimise the design; not solely of the elastomer diaphragm itself, but in addition to suggest modifications to the hardware elements that interfaced with it to increase the obtainable area for the diaphragm. This stored materials stress ranges low to remove any chance of fatigue failure of the diaphragm over the life of the valve.
