Why Ceetak uses Finite Element Analysis

เกจวัดแรงดันco2 provides knowledge to foretell how a seal product will perform underneath sure conditions and might help establish areas the place the design could be improved with out having to check multiple prototypes.
Here we clarify how our engineers use FEA to design optimal sealing solutions for our buyer applications.
Why do we use Finite Element Analysis (FEA)?
Our engineers encounter many critical sealing purposes with complicating influences. Envelope measurement, housing limitations, shaft speeds, pressure/temperature scores and chemical media are all application parameters that we must consider when designing a seal.
In เกจวัดแรงดันถังลม , the influence of those application parameters within reason straightforward to foretell when designing a sealing answer. However, if you compound numerous these components (whilst typically pushing some of them to their upper limit when sealing) it’s essential to foretell what will occur in real utility circumstances. Using FEA as a device, our engineers can confidently design and then manufacture sturdy, reliable, and cost-effective engineered sealing solutions for our customers.
Finite Element Analysis (FEA) permits us to grasp and quantify the effects of real-world situations on a seal half or assembly. It can be used to identify potential causes the place sub-optimal sealing efficiency has been noticed and may additionally be used to information the design of surrounding parts; especially for merchandise similar to diaphragms and boots the place contact with adjoining elements may must be prevented.
The software program also allows pressure knowledge to be extracted so that compressive forces for static seals, and friction forces for dynamic seals could be accurately predicted to help prospects in the last design of their products.
How do we use FEA?
Starting with a 2D or 3D mannequin of the preliminary design idea, we apply the boundary circumstances and constraints supplied by a customer; these can embody stress, pressure, temperatures, and any utilized displacements. A appropriate finite component mesh is overlaid onto the seal design. This ensures that the areas of most curiosity return correct results. We can use bigger mesh sizes in areas with much 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 parts. Most sealing materials are non-linear; the amount they deflect beneath a rise in drive varies depending on how giant that pressure is. This is not like the straight-line relationship for most metals and rigid plastics. This complicates the fabric mannequin and extends the processing time, but we use in-house tensile check services to accurately produce the stress-strain material fashions for our compounds to ensure the analysis is as representative of real-world efficiency as potential.
What occurs with the FEA data?
The evaluation itself can take minutes or hours, depending on the complexity of the part and the vary of working conditions being modelled. Behind the scenes in the software, many hundreds of hundreds of differential equations are being solved.
The results are analysed by our experienced seal designers to identify areas the place the design may be optimised to match the particular requirements of the application. Examples of those requirements might embody sealing at very low temperatures, a have to minimise friction levels with a dynamic seal or the seal may have to resist high pressures with out extruding; no matter sealing system properties are most necessary to the client and the application.
Results for the finalised proposal can be presented to the customer as force/temperature/stress/time dashboards, numerical information and animations exhibiting how a seal performs throughout the evaluation. This data can be used as validation information within the customer’s system design process.
An example of FEA
Faced with very tight packaging constraints, this buyer requested a diaphragm element for a valve application. By using FEA, we were able to optimise the design; not only of the elastomer diaphragm itself, but also to propose modifications to the hardware elements that interfaced with it to extend the out there space for the diaphragm. This saved material stress levels low to take away any chance of fatigue failure of the diaphragm over the life of the valve.
