Why Ceetak uses Finite Element Analysis

weksler pressure gauge ราคา supplies knowledge to predict how a seal product will operate beneath sure conditions and can help determine areas where the design could be improved without having to check a number of prototypes.
Here we explain how our engineers use FEA to design optimum sealing solutions for our buyer purposes.
Why can we use Finite Element Analysis (FEA)?
Our engineers encounter many crucial sealing applications with complicating influences. Envelope size, housing limitations, shaft speeds, pressure/temperature scores and chemical media are all software parameters that we should think about when designing a seal.
In isolation, the influence of these utility parameters within reason straightforward to predict when designing a sealing resolution. However, whenever you compound numerous these components (whilst usually pushing some of them to their upper limit when sealing) it is essential to predict what is going to occur in actual utility conditions. Using FEA as a device, our engineers can confidently design and then manufacture robust, reliable, and cost-effective engineered sealing solutions for our customers.
Finite Element Analysis (FEA) permits us to grasp and quantify the results of real-world circumstances on a seal half or assembly. It can be used to establish potential causes the place sub-optimal sealing efficiency has been observed and can also be used to information the design of surrounding parts; especially for merchandise similar to diaphragms and boots where contact with adjoining components could must be averted.
The software program additionally permits drive data 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 final 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 conditions and constraints supplied by a buyer; these can include pressure, pressure, temperatures, and any utilized displacements. เกจวัดน้ำยาแอร์refco is overlaid onto the seal design. This ensures that the areas of most interest return accurate outcomes. We can use bigger mesh sizes in areas with less relevance (or decrease ranges of displacement) to minimise the computing time required to resolve the model.
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 pressure varies relying on how large that drive is. This is not like the straight-line relationship for most metals and inflexible plastics. This complicates the fabric mannequin and extends the processing time, however we use in-house tensile take a look at services to accurately produce the stress-strain material models for our compounds to make sure the analysis is as representative of real-world performance as attainable.
What occurs with the FEA data?
The analysis itself can take minutes or hours, depending on the complexity of the part and the range of working situations being modelled. Behind the scenes in the software, many hundreds of thousands of differential equations are being solved.
The results are analysed by our experienced seal designers to determine areas where the design could be optimised to match the specific necessities of the application. Examples of those necessities could include sealing at very low temperatures, a must minimise friction ranges with a dynamic seal or the seal may need to resist high pressures without extruding; whatever sealing system properties are most necessary to the client and the applying.
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 evaluation. This info can be utilized as validation information in the customer’s system design process.
An example of FEA
Faced with very tight packaging constraints, this buyer requested a diaphragm part for a valve software. By using FEA, we had been able to optimise the design; not only of the elastomer diaphragm itself, but also to propose modifications to the hardware components that interfaced with it to increase the obtainable space for the diaphragm. This saved material stress ranges low to remove any chance of fatigue failure of the diaphragm over the lifetime of the valve.
