SAMAC Engineering - Vehicle Testing

Rollover

Vladimir Panlilio provided technical assistance and advice to the RCMP in their rollover testing in Terrace, British Columbia in April 2009 and again in April 2010. These tests at an abandoned airstrip yielded invaluable data, information, and hands-on training to RCMP collision reconstructionists and analysts. These exercises broaden their knowledge of vehicle and occupant dynamics in rollover events . In 2009, 12 cars were launched off a moving tilt table and documented photographically as they rolled on the tarmac. In 2010, 30 cars were rolled using a tilt table modified from the 2009 testing. The 2010 testing was the first time high speed photography was utilized so the trip and roll phases of the sequence, including several rollovers into a hydro pole, could be discretely analyzed.

Heavy Vehicle

In September 2010, Vladimir Panlilio provided technical assistance and advice to the RCMP in their heavy commercial vehicle testing at the Hanna Test Centre. The RCMP wanted to observe the weight distribution and the stopping distance of various trailers with lift axles under certain conditions. Wide base tires (Super Singles) were also demonstrated. Federal and provincial government representatives as well as trucking industry representatives – trucking companies, trailer designers/manufacturers, professional truck drivers – were invited to witness the testing and demonstrations.

Yaw Testing

Our high speed vehicle research on yaw maneuvers was published by the Society of Automotive Engineers in April 2009 (SAE 2009-01-0103). Gilles Amirault, the primary author, presented it at the International SAE Conference in Detroit. The peer reviewed paper, “Variability of Yaw Calculations from Field Testing” was authored by Gilles and Steve MacInnis. It included 2 years of testing with multiple vehicle types, varying brake levels, and different types of tires. The appropriate analytical methods to be used by both engineers and police investigators were then analyzed.

Yaw is the result of a sudden steer maneuver and is often caused by an avoidance maneuver by a driver for instance; when a driver oversteers to avoid an object on the road. The testing and research was undertaken in partnership with the Calgary Police Service. The first series of these tests was conducted in May 2007 and the second series was conducted in May 2008.

The goal of the testing was to add to the current state of knowledge of determining the speed of a vehicle which has undergone a yaw maneuver based on the tire marks left by the vehicle. This study provides accident reconstructionists with more information regarding yaw related incidents.

Vehicle Compliance Testing

Do you install seat belts or seats in vehicles? Are you concerned whether your personnel are properly protected?

If your organization is adding or modifying seats or seat belts in vehicles, your installation and testing must comply with the Canadian Motor Vehicle Safety Standards (CMVSS).

For trucking firms, city fleet managers, and new equipment manufacturers, SAMAC provides the due diligence to ensure that any non-OEM seats and restraints are certified to meet government regulatory requirements. The photographs below show some recent testing at our Calgary test bay.

If you wish to discuss compliance test requirements for any vehicles that you have altered or modified, or want to modify, please contact us.
