Increasing the efficiency of cam follower systems through energy recovery
A cam and follower system is a mechanical linkage designed to transform a rotating motion to that of a linear reciprocating motion. Cams are well known for valving in internal combustion engines but are commonly utilized in industrial processes including stamping, food processing, and textile …

Numerical Analysis of Transient, Line-Contact Problems in Elastohydrodynamic Lubrication
… example, in rolling-element bearings, gears and cam-follower mechanisms. In EHD lubrication, the contact surfaces are not only separated by a thin lubricating film, but also elastically deformed to an amount comparable to the film thickness. The film thickness in an EHD contact can be as small as …

Comparison of the force and torque transfer for different cam profiles
… and torque distribution measurements in groove cams for sinusoidal and cycloidal cam profiles. In this thesis, two different designs and apparatuses were developed and built for the static force and torque measurements in cam-follower systems. It was shown that for the constant load applied to …

Piezoelectric buckling actuators : form reduction, bidirectional control, and optimal switching
… force-displacement behavior using a closed loop cam-follower path. Finally, a dual buckling actuator mechanism is discussed which exhibits both quasi-static and dynamic motion properties through asynchronous activation control. Through the use of phase-plane analysis, an optimal switching control …

Quantifying the Response of Relative Brain/Skull Motion to Rotational Input in the PMHS Head
… posteriorly. The test event was controlled by a cam-follower-flywheel mechanism, which facilitated control of pulse parameters and provided a form of "infinite energy" so that the device and therefore the test input would not be influenced by the characteristics of the object under test. This …

The feasibility of using electrostatic charge condition monitoring for lubricant additive screening
… and electrostatic charge. During a simulated TU3 cam-follower wear test, charge signals underwent a sign inversion; this was due to a transition between tribocharging of the lubricant under running-in and mild wear, and contact potential difference generated at the onset and progression of …
