Design and construction of an experimental stand for total hip and knee prosthetics testing

The paper presents the design and construction of an experimental stand for in vitro testing of total hip and knee prosthetics. It is composed of a pneumatic circuit (two pneumatic cylinders, a rack-piston oscillating motor), an electric circuit (an electric motor of 24 V DC, a power source, a command and control circuit), a device for cycles number counting, sensors for acceleration, rotational speed and Euler's angles measurements etc.
