Ship's steering systems have changed over the ages, driven by the need for more powerful and reliable systems. Nowadays the normal practice for ship's steering systems lies into hydraulic solutions because of their excellent characteristics in terms of performances and reliability. However, the modern advancements in the electric drives field, give insights to compare the two systems, with attention to the lower masses and costs enabled by electric drives adoption. This paper describes this comparison, downstream to the conceptual design purpose of an electric drive system suited for ships of about 500 tons of load displacement and 50 m of overall length. The results confirm the hypothesis, laying the foundations for the development of ship's steering systems inspired by this studied solution.

“…The first one is modification of the motion law from the motor [7]. The second way is to modify the mechanical structure such as redesign the mechanism or adding a balance weight [8], [9]. In this work, a modification realized by adding balance weights will be discussed, through the software ADAMS which allows one to simulate the kinematic and dynamic movement and reaction of both the system and each component [10].…”

Abstract: This paper is about a mechanical solution to vibration problem of a wrapper flow pack mechanism, which is used in packaging industry. The target mechanism is the welding head of the machine where the vibration is generated, due to eccentric masses rotating with a cut-on-the-fly motion law. Consequently, production rate is limited by the vibration at 200 pieces per minute. To reduce the vibration so that the production rate can exceed over 200 ppm, two ways of improvements are considered. The first one is optimizing the motion law. The other one consists in mechanical modifications which eliminates or balance out the inertia forces derived from the eccentric rotating mass. This research implements the second way of adding balance weights and discusses the properties of it. During analysis, the software ADAMS which provides kinematic simulation is used as the analytical tool to test and examine the solutions proposed.

“…Design techniques for motion laws have reached a very good level of automation, by mean of dedicated software that aid to satisfy a set of functional specifications [1], [2] and [3]. These laws are defined by applying available parameters into well-known patterns: a classical example [4] is given by a curve-intermediate between the parabolic and the cycloidal, but with the fewest and lowest possible harmonics.…”

The vibrational effects created by machines moving parts is strictly related with the characteristics of the law of motion they implement, both in case of cam-follower devices and in case of servo system electronic cam controls. One of the most effective way to prevent these harmful phenomena is to limit the harmonic content of the law of motion by designing their curve as a combination of few, low frequencies, sinusoidal curves, but this often makes difficult to satisfy other functional requirements like precision points or constant speed intervals. In this work an original method to solve this problem is illustrated. It adds to the programming language CamOMiLe new functions to assist the functional design of mechanisms. The combination of the classical theory results with the flexibility of CamOMiLe building block approach makes possible to address a large number of practical applications and two examples of them are illustrated.
