Ventilation system manufacturer Soler & Palau needed a faster way to evaluate design alternatives
Soler & Palau (S&P) is one of the leading ventilation manufacturers in the world. Its systems are known for being well-designed, easy to install and extremely durable. Designing a ventilation system can be a lengthy endeavor due to the complexity of the assembly. It consists of an inlet with a protective mesh, duct, rotating impeller, electric motor, exhaust, louver shutter and other components. “The relative position of every part is critical to achieving an optimized design,” says Josep Vilanova, development and support manager, Soler & Palau. “For example, if the rotating impeller blades are located near fixed parts as supports, an objectionable noise is usually produced.”
Because there are so many design variables, only a limited number of design concepts can be evaluated with physical prototypes as a single prototype can take up to one month to build. S&P can’t risk delaying new product introductions because a fan that is late to market can be instantly out-dated. The company needed a way to evaluate multiple design concepts quickly to speed the introduction of optimized new products.
S&P took a new approach with its PVP-SL ventilator series, a family of six new heliocentrifugal fans that deliver low noise and high performance and provide direct coupling for installation in impulsion or aspiration duct lines. S&P used the development of this product as a test bed to optimize its usage of engineering methods based on NX. The goal was to increase product performance while reducing development time.
S&P engineers used the software to model assemblies in 3D. Then, using NX visualization capabilities and third-party analysis programs, they evaluated the virtual assemblies electronically. They also used the software for electronic communication and collaboration with manufacturing.
In the early phases of the design cycle, S&P engineers evaluated four different virtual prototypes in a single week. The engineers also evaluated several additional structural and aerodynamic alternatives. “Even if we had not reduced the design time, our efforts would have been justified by the fact that we were able to consider more design variations,” says Vilanova. “This made it possible to significantly improve the performance of the product.”
Once the product definition was finalized, engineers provided digital models for tooling, molds and dies to suppliers that machined them directly from the model. This ensured the accuracy of the tooling and also reduced the lead time required to move into production. “We reduced the time-tomarket by about 40 percent,” says Vilanova. “Beyond that, the existence of the 3D digital model meant that we were able to quickly make modifications to the product design and communicate them to downstream manufacturing sources.”
S&P now uses NX for complete digital product development from initial concept to finished product. The company creates, simulates, optimizes, documents, builds and tests products within an integrated digital environment, involving its extended development team and the supply chain in the product development process.
Keys To Success:
Client's Primary Business:
Soler & Palau is a leader in the European ventilation market, producing axial-flow fans, roof fans, in-line fans and centrifugal direct-drive fans for industrial applications and axial extractors, centrifugal extractors, cooling fans and heaters for home use.
"NX is helping us develop new products in less time by providing tools to create virtual prototypes. With NX, we can evaluate multiple design alternatives before we commit to a physical implementation."
