Effect of stiffness and movement speed on selected dynamic torque characteristic of hydraulic-actuation joystick controls for heavy vehicles

Article Abstract:

A study conducted to quantify the effects of joystick stiffness and movement speed on the dynamic torque characteristics of hydraulic-actuation joystick controls, as found in off-road vehicles, as one of the initial steps towards the development of joystick design protocol. The most important result of this work is that the dynamic torque characteristic incurred during hydraulic-actuation joystick use is substantial, while peak torque values were not very different between the fast and slow motion conditions.

Off-road machine controls: investigating the risk of carpal tunnel syndrome

Article Abstract:

This article discusses the use joystick controllers in off-road machines and the possibility of acquiring carpal tunnel syndrome. The authors maintain that the wrists left to right movement when operating a joystick increases the risk for carpal tunnel syndrome.
