Finite Element Analysis supplies knowledge to predict how a seal product will function underneath certain situations and might help establish areas the place the design can be improved with out having to check a number of prototypes.
Here we clarify how our engineers use FEA to design optimum sealing options for our buyer functions.
Why do we use Finite Element Analysis (FEA)?
Our engineers encounter many critical sealing applications with complicating influences. Envelope size, housing limitations, shaft speeds, pressure/temperature ratings and chemical media are all software parameters that we must consider when designing a seal.
In isolation, the impact of these utility parameters is reasonably simple to predict when designing a sealing solution. However, if you compound numerous these components (whilst usually pushing some of them to their higher limit when sealing) it is essential to predict what’s going to happen in actual utility circumstances. Using เครื่องมือตรวจวัดความดันเลือดเรียกว่า as a device, our engineers can confidently design and then manufacture robust, dependable, and cost-effective engineered sealing options for our prospects.
Finite Element Analysis (FEA) allows us to grasp and quantify the consequences of real-world situations on a seal half or assembly. It can be utilized to determine potential causes where sub-optimal sealing performance has been observed and may also be used to guide the design of surrounding parts; particularly for products such as diaphragms and boots the place contact with adjoining components could must be prevented.
The software program additionally allows pressure knowledge to be extracted in order that compressive forces for static seals, and friction forces for dynamic seals can be precisely predicted to help customers within the ultimate design of their products.
How can we use FEA?
Starting with a 2D or 3D model of the initial design idea, we apply the boundary circumstances and constraints supplied by a customer; these can embrace stress, drive, temperatures, and any applied displacements. A appropriate finite element mesh is overlaid onto the seal design. This ensures that the areas of most interest return correct results. We can use larger mesh sizes in areas with less relevance (or decrease ranges of displacement) to minimise the computing time required to solve the model.
Material properties are then assigned to the seal and hardware components. Most sealing materials are non-linear; the quantity they deflect beneath an increase in force varies relying on how giant that pressure is. This is not like the straight-line relationship for many metals and rigid plastics. This complicates the material mannequin and extends the processing time, but we use in-house tensile test services to accurately produce the stress-strain materials models for our compounds to ensure the analysis is as representative of real-world efficiency as attainable.
What occurs with the FEA data?
The analysis itself can take minutes or hours, depending on the complexity of the half and the range of working conditions being modelled. Behind the scenes in the software, many lots of of 1000’s of differential equations are being solved.
The outcomes are analysed by our skilled seal designers to establish areas where the design may be optimised to match the specific necessities of the application. Examples of these requirements may include sealing at very low temperatures, a have to minimise friction ranges with a dynamic seal or the seal may need to face up to high pressures without extruding; no matter sealing system properties are most important to the customer and the appliance.
Results for the finalised proposal may be offered to the client as force/temperature/stress/time dashboards, numerical information and animations displaying how a seal performs all through the evaluation. This data can be utilized as validation data within the customer’s system design process.
An example of FEA
Faced with very tight packaging constraints, this buyer requested a diaphragm component for a valve utility. By utilizing FEA, we have been capable of optimise the design; not solely of the elastomer diaphragm itself, but also to propose modifications to the hardware elements that interfaced with it to extend the obtainable area for the diaphragm. This saved materials stress ranges low to take away any risk of fatigue failure of the diaphragm over the lifetime of the valve.
