The impact resistance of a hip protector is evaluated using a
Dynatup 9250 HV impact test system.
The Challenge
Accidental falls are a leading cause of injury among elderly people.
Specifically, hip fractures are the largest single injury resulting from falls
in patients aged 65 to 74 years. Biomechanical analysis shows that maximum
force on the hip when falling approaches three times body weight. This can be
reduced by about a third using a protective device. The device must be able to
absorb and dissipate impact energy and be comfortable enough to wear on a daily
basis.
Our Solution
Evaluation of the performance of a hip protector is conducted by simulating a
fall using an impact test system. By specifying crosshead weight, drop height,
velocity and acceleration, test configurations can be designed to accurately
reproduce forces produced during a fall.
The Dynatup® 9250 HV impact testing system allows for all of
these configurations, and the Impulse™ machine control and data
acquisition system simplifies measurements of maximum load, time to max load,
time to failure, total time, impact energy and energy to max load. Results from
such tests assist researchers and engineers in the design of protective
devices, and help physicians properly prescribe these devices to prevent
patient injury.
