With a total of 3 patents to his name, Hartnagel's work has implications for various engineering applications.

Latest Patents

Hartnagel's latest patents include a method for determining an unbalance of a shaft-elastic rotor with reference to the outward deflection. This innovative method involves creating a rotor model that describes the geometric shape and material properties of the rotor. The compliance of the rotor model is calculated at a measurement point and at the center of gravity of the rotor at an assumed speed. The method allows for the measurement of outward deflection at the measurement point, enabling the calculation of the equivalent modal unbalance that needs to be compensated for.

Another significant patent is a method and device for determining the static unbalance of a body. This method utilizes a center-of-gravity weighing scale and electric displacement sensors to measure the position of the locating surface of the body. The process involves computing the eccentricity of the locating surface and weighing the body to record the mass and position of its center of gravity. The unbalance of the body is then computed from the measurement signals and eccentricity.
