Boeij (2009) Multi-Level Contactless Motion System In machine design, the acceleration and velocity of moving parts are often constrained by mechanical bearings for guidance and cables for transferring power and information. These factors not only limit the stroke and functionality of the machine, but additionally disturb the motion of the mover, thereby reducing reliability, speed, and accuracy.…”

“…This thesis focuses on the removal of these constraints and their effect on the system-level design of the machine. Three different contactless techniques can be incorporated into the motion system design to overcome the limitations of bearings and cables [23]. Hirano et al ( 2017) used a musculoskeletal model and a Kinect TM based on a contactless motion analysis approach to measure muscle activation [24].…”

Objective: In this paper, a proposed technique of motion transmission is introduced, which is based on the crank-rocker principle of motion. The energy transmission action is performed through magnetic force, in which no direct connection is made between the energy source input and the energy load output. Also, to illustrate the concept of motion and to approve the continuity of energy transmission using this proposed technique, a simple model of this mechanism has been built and run, showing the basic sequence of operation. Methodology/analysis: In this mechanical transmission mechanism, one side is rotating and the other side is vibrating, in which any side is energy input (which is usually the vibrating rocker), and the other side is energy output (which is the rotating crank). That seems similar to the classical crank-rocker machine in the four-bar mechanism, but without direct mechanical contact between the input and output energy stream. The concept of motion and mathematical analysis with structuring conditions is provided in this paper, where the dynamic analysis of the system is left for future work. A pilot physical prototype is manufactured and experimentally tested, validating the proposed design. Findings: The structural parameters of this proposed contactless crank-rocker machine have been modelled and simulated using the MATLAB program. It shows that these parameters could be selected and optimized to guarantee the minimum conditions for continued energy transmission. Based on these parameters, a simple model has been built and operated, which illustrates the concept of motion and validates the finding of MATLAB simulation. Novelty/improvement:Contactless crank-rocker motion is a very promising technique. It is possible to apply it in many applications, like the energy harvesting area, and it could be employed certainly in specific designs, such as MEMS, where no other motion transmission types can be used.
