Imagine the power of being able to predict and design the future..
Computer Aided Engineering (CAE) is one of the most powerful virtual product design development tools available for predicting and optimizing the behavior of components and complete systems for operational use. Designs can be optimized and design flaws eliminated, and manufacturing problems resolved early on in development with some of the most sophisticated analytical tools available.
Segula EES offers a complete set of solutions for optimization, ranging from use of optimization methods, like sizing, shape and topology optimizations, or calculation of response surfaces, to a broader process management to analyze and optimize designs across multiple disciplines. Our “Analytically Driven Design” approach is an accelerated development approach where the design is driven forward with analytic software tools that are tightly coupled with design engineering and manufacturing teams. The process allows designers and engineers to quickly iterate back and forth in perform many “what-if” scenarios. This is where alternatives are compared and filtering out as design weaknesses are eliminated before prototype testing and further production planning.
Linear and Non-Linear statics analysis is used for design and verification of products using a variety of structural and thermal loads. Knowing how a design will perform under different statics load conditions allows EES engineers to recommend changes prior to physical prototyping, thus saving clients both time and money. Non-linearity includes geometric and material non-linearity effects. In the real world, most engineering problems contain some kind of nonlinear effect. Sometimes, EES uses simplified linear approximations as a faster and more efficient alternative to non-linear analysis.
Frequency and buckling analyses are critical components of a design and verification process. Inherent vibration modes in structural components or mechanical support systems can shorten equipment life and cause unexpected failures. We evaluate natural frequencies or critical buckling loads and recommend design changes to improve product performance.
Contacts are not applied by default in most finite element analysis even though frictional contact is the most common in almost all engineering situations. Utilizing the latest algorithms in our analysis software, EES can help our clients predict the contact stresses in your application, be it an insertion/extraction, press-fit, or frictional contact, to help with design and verification.
Structural components such as a control arms might be strong enough to withstand a single applied load. But what happens when the part operates over and over, day after day? To predict component failure in such cases requires what’s called fatigue or durability analysis. Computer simulations determine how well parts will hold up during cyclic loading. Results are important in calculating and verifying safe part lifetimes. All parts and structures subjected to cyclic mechanical and thermal loading will suffer from fatigue. Whether our clients design engine parts or bridges, we can help predict how fatigue will affect the overall life of the product, and identify the areas that may be critically damaged.
A large portion of our business involves consumer safety concerns and simulating regulated performance criteria as original equipment manufacturers strive to provide maximum protection to vehicle occupants under any condition. Behind this effort is advanced virtual computer simulation using state of the art software to simulate a variety of global requirements such as:
- FMVSS crashworthiness regulations like frontal, rear and side impact, roof crush resistance
- ECE regulations like deformable 40% offset, frontal impact, rear impact, euro dynamic side impact.
- Insurance/consumer requirements like IIHS, RCAR, AMS
- Bumper Testing for both high and low speed impact tests
- FMVSS requirements for occupant safety like Free Motion Head Impact, Seatbelt Anchorage, Child Restraints anchorage system, sled test occupant simulation, knee bolster simulation, steering control system
- ECE regulations including luggage intrusion, steering control system, pedestrian safety
Moldflow analysis is a plastics flow simulation that allow our clients to determine the manufacturability of their part in the early design stages and avoid potential downstream problems which can lead to production delays and costly overruns.
Segula EES engineers have demonstrated to clients that Moldflow analysis can
- Increase the confidence in the manufacturability of design
- Reduce part cost by improving material utilization
- Improve part strength and quality
- Optimize design to client’s production capabilities
- Help select material characteristics
- Do advanced analysis like warpage and shrinkage
Metal forming analysis is a virtual simulation of the process by complete simulation of press action in a stamping operation to form sheet metal parts. The analysis provides visual design verification in the virtual world without need for expensive and time consuming prototyping. All aspects of forming: Stamping, Trimming, Flanging, Hemming and Springback Analysis can be evaluated.
Segula EES engineers have vast experience in this domain and have state of art software to assist with modeling and simulations.
Blank Sizing and Material Utilization. As a precursor to the stamping process, custom software allow Segula EES engineers to help clients quickly do blank sizing and material utilization studies to minimize scrap.
Material Cost Reduction Studies. Material cost reduction can be achieved through a variety of methods. This includes complete design using alternate materials, material substitution and down-gauge studies, material utilization studies, among other methods. Segula EES engineers can help evaluate client’s material needs: from furniture and other consumer products to defense and aerospace needs.
Manufacturing Analysis. Wide variety of computer simulation based evaluation is now available to model and virtually simulate manufacturing feasibility for extrusion, tube bending, hydro-forming, casting, and forging analysis. Custom software available allow Segula EES engineers to quickly evaluate manufacturing process for client applications to help with design recommendations to improve their products from a manufacturing perspective thereby offering cost savings through avoidance of costly and time consuming trial and error test methods.
Reliability and Robustness. Reliability-based robust design for products like automobiles can be offered through mathematical and mechanical models for actual computation methods and practices on the basis of the research of failure physics and combined with the reliability-based test and statistical analysis of failure data. We utilize latest software to help clients develop predictive models for reliability and robustness engineering.
Segula EES engineers have applied principles of DFSS to analysis for automotive and other components for improving designs.
Stochastic Analysis. Stochastic or random vibrations occur in a variety of applications of mechanical engineering. We can answer questions like how structures respond to random excitation and quantify random behavior.
