Bentley’s $198,725 Flying Spur sedan is extra sustainable attributable to ESI Group’s digital prototyping course of

Engineers check every element in digital type to cut back the automotive’s total weight and cabin noise earlier than constructing any bodily elements.

Bentley labored with ESI Group to make use of a digital prototyping course of to cut back cabin noise and the general weight of the 2021 Flying Spur V8.

Luxurious automotive maker Bentley is utilizing digital prototyping to create a quieter experience within the Flying Spur and make all the course of greener. The carmaker is working with ESI Group to take the design work digital.

Simon Noble, acoustic engineer at Bentley Motors, mentioned in a press launch that digital prototyping helped the corporate optimize every element of the automotive just about earlier than constructing the bodily elements.

“Digital prototyping means fewer prototypes should be constructed, and we cut back our testing mileage,” he mentioned. “It additionally helps affect the design and engineering of the automotive at an early stage and affords vital advantages within the in depth testing section.” 

The 2021 Flying Spur is $198,725, based on Automobile and Driver. The 2021 Flying Spur V8 is 100kg lighter than the Flying Spur 2021 W12, based on the corporate.

The ESI Group used digital prototyping to create digital mock-ups that helped establish noise, vibration and harshness earlier than constructing a bodily model of the automotive. 

“The digital prototyping helped to cut back bodily elements within the check section and save time,” Jonas Fredriksson, managing director ESI Northern Europe, mentioned in a press launch.

With the normal prototyping course of, every design resolution needs to be validated with a bodily product to review the conduct of every half towards one another and its affect on the ultimate product, based on a spokesperson from ESI. 

“This takes time and has a value in uncooked materials,” Fredriksson mentioned.

Utilizing a digital design course of, all the pieces is finished in a digital mockup with a digital illustration of every half and the automotive as an entire. 

“Each alternative of fabric and element positioning is not bodily prototyped to be examined, however as an alternative each check is run just about as a simulation,” Fredriksson mentioned. “This answer gives way more freedom: the variety of bodily prototypes is decreased whereas growing the variety of checks that may be accomplished.”

By performing life like digital simulation of sound and materials conduct of the design, Bentley eliminates the necessity to make bodily prototypes. The digital course of permits designers to validate and check just about, get it proper from the start and keep away from pricey modifications, waste of prototypes and time.

“The digital design course of makes the design of the automotive extra economical by way of time and value and particularly uncooked materials,” Fredriksson mentioned. 

Bentley described the method this fashion in a press launch:

“This zero-waste, extremely progressive course of can be according to Bentley’s ground-breaking Beyond100 technique, focusing on sustainable international mobility management. The corporate’s formidable purpose is to be end-to-end carbon impartial by 2030, with the Crewe operations local weather constructive thereafter.”

The ESI spokesperson mentioned that the digital course of makes it simpler to check supplies whereas additionally consuming much less and polluting much less.

A Bentley spokesperson mentioned that engineers carried out weight optimization processes for 40 parts on the Flying Spur to maintain the automobile’s weight as little as attainable.

ESI additionally works with Renault to do digital prototyping. The spokesperson mentioned that Renault bought the very best ranking on Europe’s security check certification for the Clio 5 with a single bodily prototype. Different Renault fashions wanted anyplace from 10 to twenty-eight further prototypes to move the certification course of.

The ESI group has 50 years of expertise with digital prototyping and has labored with automotive corporations, together with Safran, Audi, Latecoere, Kion Group, Volkswagen and Honda, in addition to protection and naval corporations.
