Realistic Simulation Supports Expansion of the London Underground

By Akio

Dubbed “one of the most complex tunneling projects in the U.K.,” the Bond Street Station Upgrade (BSSU) project is being carried out to satisfy growing traffic demands within London’s busiest shopping district, the West End.

Upon its completion, Bond Street Station’s daily passenger numbers are expected to rise from 155,000 to 225,000.

A project this complex in nature has to consider the existing tunnel infrastructure, as well as the stress and strains imposed by the surrounding soil layers for the development of new tunnels.

Dr. Sauer and Partners was contracted to provide such tunneling expertise. The company took on responsibility for preliminary-to-detailed design and construction on all BSSU sprayed concrete lined (SCL) tunnels.

Using FEA simulation, they were able to virtually test the ground through which the tunnels are being dug alongside the existing tunnel structures.


This realistic assessment enabled them to improve upon the preliminary design, as well as bring greater confidence to the overall approval process.

Test tube transport: the Hyperloop nears reality

Imagine traveling in capsules sucked through a tube using low air pressure and magnetic acceleration to achieve speeds of up to 760 miles (1,223 km) per hour. That’s the idea of the California Hyperloop, which could eventually cut the travel time between Los Angeles and San Francisco to a mere 30 minutes, compared with today’s one-hour flight or six-hour car journey.

As soon as next year, a full-scale test track will begin construction in Quay Valley, a proposed sustainable community located between California’s two major metropolises.

The Hyperloop is a system that not only makes sense because it’s cheaper to construct, but it’s also sustainable so it’s cheaper to run,” says Dirk Ahlborn, chief executive officer of Hyperloop Transportation Technologies, Inc. “It changes the world.”

Tesla founder Elon Musk first laid out his Hyperloop vision in 2013 and invited others to take up the challenge. Turning the idea into a full-scale model in just three years may seem fast, but, as Mr. Ahlborn points out, it took a decade to get to the moon—“a way more difficult task,” he says. “The Hyperloop technology sounds like science fiction but, in the end, everything we’re doing already exists. The Quay Valley track is necessary to find out how to optimize the technology.”

The Hyperloop concept is similar to the pneumatic tubes used by banks to carry cash and documents, except that the passenger capsules would be sucked through the tube by controlled propulsion. A capsule (with large doors for speedy boarding) would enter a tightly sealed exterior shell. The tubes would probably be constructed from steel—although other materials, including fiberglass, are being considered—and covered with solar panels to supply the system’s energy. Low air pressure—of around 100 Pascals—would reduce air resistance inside the tube, while magnetic levitation and an air cushion would allow the capsule to hover above the tube’s surface. The straight track would further aid speed. As on a flight, passengers would sense how fast they are moving only when the capsule accelerates, slows or turns.

The Quay Valley track will allow engineers to work out optimum capsule size and boarding procedures. Each capsule is currently expected to seat 28 passengers and depart every 30 seconds during peak times, allowing a full-size Hyperloop to transport some 3,360 passengers an hour.

The Hyperloop would be elevated on pylons, making it possible to place the route above existing infrastructure such as highways, while also simplifying the process of obtaining right of way and minimizing the environmental impact.

More importantly, the pylons would be flexible enough to withstand earthquakes, in the way that pylons built in the 1970s to carry Alaska’s oil pipeline have proved resilient to such shocks, Mr. Ahlborn notes. As an enclosed system, the Hyperloop would also be impervious to harsh weather.

Perhaps more revolutionary than the technology is the way the Hyperloop team itself works. As well as partnering with companies and universities, more than 300 experts from 21 countries have been brought onto the team, working remotely online. Although they don’t get paid—most hold day jobs as engineers—they do get company stock options. “They’re driven by passion,” says Mr. Ahlborn.

The Hyperloop is groundbreaking in a commercial sense, too. It is expected to cost $16 billion to build, versus $68 billion for a comparable California high-speed rail line. Ticket prices for the Los Angeles-San Francisco stretch, at $20- $30, would be far cheaper than flying, and even that business model is open to disruption. “Do we need tickets?” asks Mr. Ahlborn. “Or are there other ways in which we can generate enough income.” Maybe the Hyperloop could “make more money having more people ride and we can say it’s free. Or maybe it’s free at certain times, and at peak times it costs a bit,” he adds.

The Hyperloop turns conventional infrastructure on its head, from its technology to its crowdsourcing. “Usually these things are done behind closed doors in a boardroom. We’re trying to be open. We’re using the community to do everything,” Mr. Ahlborn says. The Hyperloop “is a first for a lot of things.”

Volvo’s New XC90 Wins the FAI 3rd Creativ’Experience Award


 This year’s 30th annual “Festival Automobile International” (FAI) event thrilled the automotive industry with the presentation of 2014’s innovative technology and design accomplishments. The “Creativ’Experience” award has proven to be one of the most exciting moments during the festival.A driverless car, enhanced virtual capabilities, hyper connectivity and new lightweight materials were just a few of the impressive breakthrough achievements featured at this premier event.

2015 “Creativ’Experience award” Winner-Volvo (XC90)

It is the Swedish brand Volvo XC90 that captured the “Creativ’Experience award” with its revolutionary driving assistance system. The new XC90 offers two new safety technologies: “A system that tightens safety belts and activates energy-absorbing features in the seats if the car wanders off the road and automatic braking if a vehicle pulls in front of the XC90” ( social interaction and mobility features interact with the surrounding environment and people which is good news for drivers that have to deal with over-crowed roads and urban traffic. “We see that eventually our Volvos will not crash at all and that very much leads us to autonomous driving” said Volvo Cars Chief Information Officer Klas Bendrik, in an interview.

Another application for this technology is bicycle recognition which uses the Volvo cloud database. A two-way connection shares the exact positions of the cyclist and car to alert the driver of a potential collision.
