Η Volvo έχει εμμονή με την ασφάλεια και πριν από μερικές ημέρες, σε μια παρουσίαση του XC90 στον ειδικό τύπο, προσομοίωσε μια έξοδο σε ένα χαντάκι, με το XC90 να απογειώνεται, ώστε να μας δείξει το πως λειτουργεί το σύστημα προστασίας “Run-off Road Protection“. Αυτό σφίγγει τις ζώνες ασφαλείας, αλλάζει τη θέση του καθίσματος ώστε να υπάρξει καλύτερη προστασία στη σπονδυλική στήλη των επιβατών, ενεργοποιεί τους αερόσακους και αποσυνδέει το πεντάλ του φρένου, ώστε να δημιουργεί επιπλέον ζωτικός χώρος στα πόδια του οδηγού. Δες τα ακόλουθα video, με τη δοκιμή να γίνεται ρομποτικά με 80 χλμ/ώρα.
The art of turning an amusement park ride into a run-off road test at Volvo Cars Safety Centre
Volvo Cars’ safety expert Anders Axelson knows that brilliant ideas can pop up in the strangest of circumstances. A visit to Legoland with his twin daughters in 2007 inspired Anders to turn an amusement park ride into an efficient test method in Volvo Cars’ quest for better protection in run-off road crashes.
“Watching people being thrown in all directions during a ride in the ‘Robocoaster’, I suddenly realised that those rapid, random movements resembled the violent forces occupants in a run-off road crash are exposed to,” says Anders Axelson.
Run-off road crashes had been on Anders’ mind since 2006 when Volvo Cars intensified the development of technology to help protect car occupants in these common and complex scenarios.
Based on real-life accident data, Anders Axelson’s team initiated three complete vehicle crash test track methods, called ‘Ditch’, ‘Airborne’ and ‘Rough terrain’, for evaluating the consequences of various run-off road scenarios.
Analysing films from a large number of these tests confirmed that being thrown out of the ideal, firmly strapped-in seat position correlates well with potential injury-causing mechanisms seen in real-world crashes.
Searching for a test method “The engineers developed promising solutions to actively retract the occupants in order to keep them in position. But since running complete cars into the terrain is a time-consuming and expensive test method, we needed a quicker and cheaper solution to evaluate the ideas,” Anders Axelson recalls.
The stroke of genius conveniently came on a family trip to Legoland in Denmark. At the time, Anders’s twin girls were too small for the ‘Robocoaster’, but after watching other kids being shaken by the robot arm, he realised that the ride had potential beyond making kids scream with joy.
Back at the office, Anders started searching for a similar robot that could be programmed to mimic the exact movement patterns that Volvo Cars had recorded during the complete vehicle run-off road crash tests.
Unique test rig “The industrial robot manufacturer ABB had the technology and the knowledge to programme a machine designed for precision work to move a car seat around in a seemingly random pattern. It worked brilliantly,” says Anders Axelson.
A vehicle seat and restraint system is mounted on the multi-axial industrial robot. The robot, which is used together with a crash test dummy, can be programmed to simulate the occupant kinematics during crucial parts of run-off road scenarios.
During the development work of the all-new XC90 and upcoming cars based on the company’s new scalable architecture, Volvo Cars’ own ‘Robocoaster’ has been used to find the combination of safety belt geometry, rapid belt retraction and seat design that helps keep the occupant firmly in position in run-off road scenarios.
World-first run-off road safety solution The result is a world-first run-off road protection package that includes rapid electrical safety belt retraction as well as unique ‘energy-absorbing’ functionality in the seat that cushions the vertical forces that occur in a ‘hard landing’ in the terrain.
“The most valuable result from the ‘Robocoaster’ tests is probably the insight into how well the safety belt retraction interacts with the enhanced side support in our new seat generation,” says Anders Axelson.
By the way, Anders Axelson never went on the ‘Robocoaster’ ride during that visit to Legoland. “No way. Violent rides like that make me sick,” he says with a smile.
ALL-NEW VOLVO XC90 ORDER BOOKS OPEN
- Volvo’s Gothenburg factory accepts new orders for the first vehicle from the new SPA platform
- Order system opens with an influx of pre-orders placed at dealers
- New engine and options now available from preview customer feedback
Volvo Car Corporation has opened the order books for the all-new Volvo XC90, the first vehicle to be built on its brand new in-house designed and built chassis, using its own in-house designed and built engines.
Amongst the first orders to be placed are the lucky 1927 owners of the First Edition, 53 of them being from the UK. Customers who have already placed orders at dealers will have their order accepted by the factory and become the some of the first owners to have their vehicle delivered.
Having been able to preview the all-new XC90 to a number of customers and from feedback already received, a number of additions have been made available to order. Principle changes have been the introduction into the UK of the 320hp T6 petrol engine and the addition in the availability of the auxiliary heater on the D5. The auxiliary heater, standard on the T8 Twin Engine, allows the driver to pre-condition the vehicle cabin to a set temperature so that it is ready for when the car is required.
The XC90 will be built on Volvo’s brand new SPA chassis. Designed under the leadership of Thomas Ingenlath, the new vehicle shows the new design direction of Volvo Cars, together with its new interior and centre-piece, the tablet style centre touchscreen.
The XC90 is the first car to be powered solely by Volvo’s new Drive-E engine range. Available to order from launch with either an all-wheel-drive (AWD) D5 225hp diesel, an AWD T6 320hp petrol or an AWD T8 Twin Engine petrol plug-in hybrid with 400hp.
The all-new Volvo XC90 First Edition was sold exclusively on-line and was sold out within 47 hours, at peak time seven cars were sold every minute. Only 1927 cars were made available, a celebration of the year that Volvo was founded, all in one specification level and in the same exterior colour and interior upholstery.
