Pushing is one of the most common manual work tasks and prevention of work-related injuries in this field holds a very large socio-economic potential. The AnyBody Modeling System™ enables simple investigations of muscle efforts and joint forces depending on postures and other workplace parameters.
In this example a hospital employee is pushing a bed with a total mass of 200 kg forward at an acceleration of 0.3 m/s^2. The duration of the push is 1.5 second. It is possible to choose three different heights of the horizontal handle bar: 0.9m, 1.1m and 1.3m.
Simulation reveals that the muscle effort as well as the elbow joint force during the push is smaller for the high position of the handle bar.
