Hurricanes experienced in Cambridge
Cambridge Consultants is testing its novel wind simulator, before delivery to The University of Western Ontario (Western) for pioneering research into wind damage on low-rise buildings.
Following a year of design and development work, Cambridge Consultants is testing its novel wind simulator, before delivery to The University of Western Ontario (Western) for pioneering research into wind damage on low-rise buildings With advice on wind behaviour from RWDI-Anemos, Cambridge Consultants has devised a unique wind simulation system that is capable of varying the speed and direction of air flow up to seven times a second

Through-wall vision technology from Cambridge Consultants promises a new edge for security and emergency personnel.
This allows an array of actuators to emulate the real-life swirling effects of destructive winds.
The design can also dynamically adjust flow rate to maintain pressure - even as a structure begins to disintegrate.
The results of Western's research are expected to lead to more formal techniques for weather-proofing low-rise buildings in hurricane prone areas.
The simulator takes the form of modular pressure actuators, which are mounted against the exterior surface of a test structure.
Each actuator can generate pressures equivalent to a category 5 hurricane, enabling realistic loads to be applied to full-size buildings for the first time.
A real-time control system, also being developed by Cambridge Consultants, will enable arrays of actuators to be co-ordinated to simulate complex wind effects over the entire surface of a test structure.
Western will use this simulation technology to apply realistic wind patterns onto real-world structures, beginning with a two-storey, pitched-roof dwelling currently nearing completion at 'The Three Little Pigs' research facility in London, Ontario.
Following completion of Cambridge Consultants' development tests, Western expects to start commissioning the simulator this summer, using an initial batch of 10 actuators on a rig that will become a permanent facility for testing building materials.
Around 100 modular actuators will then be fabricated, to create a wind simulator large enough to test complete low-rise buildings.
