Why Ceetak uses Finite Element Analysis

Finite Element Analysis offers information to foretell how a seal product will function beneath certain conditions and can help establish areas where the design can be improved with out having to test multiple prototypes.
Here we explain how our engineers use FEA to design optimal sealing solutions for our customer applications.
Why will we use Finite Element Analysis (FEA)?
Our engineers encounter many crucial sealing functions with complicating influences. Envelope size, housing limitations, shaft speeds, pressure/temperature scores and chemical media are all utility parameters that we must contemplate when designing a seal.
In เครื่องวัดแรงดันเกจที่นิยมใช้ , the influence of these application parameters is reasonably straightforward to foretell when designing a sealing solution. However, when you compound a quantity of these components (whilst often pushing some of them to their higher limit when sealing) it’s essential to predict what goes to occur in real utility situations. Using FEA as a tool, our engineers can confidently design after which manufacture strong, dependable, and cost-effective engineered sealing solutions for our customers.
Finite Element Analysis (FEA) permits us to know and quantify the results of real-world circumstances on a seal half or meeting. It can be used to identify potential causes where sub-optimal sealing efficiency has been noticed and can additionally be used to information the design of surrounding components; particularly for merchandise similar to diaphragms and boots the place contact with adjacent components could have to be avoided.
The software additionally permits force data to be extracted so that compressive forces for static seals, and friction forces for dynamic seals may be precisely predicted to assist clients in the last design of their products.
How can we use FEA?
Starting with a 2D or 3D model of the initial design concept, we apply the boundary situations and constraints equipped by a buyer; these can embody stress, force, temperatures, and any applied displacements. A suitable finite element mesh is overlaid onto the seal design. This ensures that the areas of most interest return accurate outcomes. We can use larger mesh sizes in areas with less relevance (or lower ranges of displacement) to minimise the computing time required to unravel the mannequin.
Material properties are then assigned to the seal and hardware components. Most sealing materials are non-linear; the quantity they deflect beneath a rise in drive varies relying on how large that drive is. This is unlike the straight-line relationship for many metals and inflexible plastics. This complicates the fabric mannequin and extends the processing time, however we use in-house tensile test facilities to accurately produce the stress-strain materials models for our compounds to ensure the evaluation is as consultant of real-world performance as potential.
What occurs with the FEA data?
The analysis itself can take minutes or hours, relying on the complexity of the part and the range of working situations being modelled. Behind the scenes in the software, many hundreds of hundreds of differential equations are being solved.
The outcomes are analysed by our experienced seal designers to determine areas the place the design can be optimised to match the precise necessities of the appliance. Examples of these requirements could embody sealing at very low temperatures, a need to minimise friction levels with a dynamic seal or the seal might have to resist excessive pressures without extruding; no matter sealing system properties are most essential to the customer and the appliance.
Results for the finalised proposal may be offered to the customer as force/temperature/stress/time dashboards, numerical data and animations exhibiting how a seal performs all through the analysis. This info can be utilized as validation information in the customer’s system design course of.
An example of FEA
Faced with very tight packaging constraints, this customer requested a diaphragm element for a valve utility. By using เกจวัดน้ำยาแอร์refco , we have been capable of optimise the design; not solely of the elastomer diaphragm itself, but also to suggest modifications to the hardware components that interfaced with it to extend the available space for the diaphragm. This saved material stress ranges low to take away any chance of fatigue failure of the diaphragm over the life of the valve.
