“…The aim is to guarantee a continuous workflow between a process stage and the following one, overcoming the weaknesses of a trial-and-error approach [2]. Among the several SE methodologies, the Model-Based System Engineering (MBSE) [3] is one of the most implemented; instead of using document-based information interchange as its primary method, it focuses on developing and utilizing domain models [4,5].…”

System Engineering (SE) methods and principles are nowadays widely adopted in the product development processes, especially in the industrial sector, where saving production time and costs are primary goals. This work describes an application of a particular SE methodology, the V-model based design, in which the system development lifecycle is divided on the basis of a graphical V-shaped scheme, called V-model. Following this approach, a new concept of Charging Arm for Robotic Train Inspection Monorail (TIM) of Large Hadron Collider (LHC) at CERN (Conseil Européen pour la Recherche Nucléaire) has been developed. The current Charging Arm version is affected by several issues and limits that have led to the necessity of a new solution. Starting from the first stages of Functional Requirements (FRs) definition and decomposition (left side of the “V”), a new concept has been implemented, in order to be tested for its verification & validation (right side of the “V"). As part of the principles of SE, the process has been based on virtual models of the product and on virtual simulations of its operation, rather than on the realization of time-consuming and expensive physical models and tests, even if a final physical prototype has also been built and some physical operative tests have also been carried out on it. These tests have showed that the new product appears to fulfil each one of its FRs and overcome the limits imposed by the previous version. The future commissioning and operative tests in the real operating condition and location shall definitely validate the new product.

“…The Simscape module based on the Matlab Simulink platform provides a convenient block diagram based operating environment for modeling and simulation, which has gradually become mainstream commercial software for multi-physics mechanism analysis [27]. The NABE-RE presented in this study is mainly composed of two kinds of physics: hydraulic physics and rigid-body physics.…”

Multi-rope elevators are widely used in modern buildings. However, problems such as vibration, noise, uneven wear of key components and shortened life caused by the uneven distribution of rope tensions are still unsolved in the elevator industry. In order to balance the different tensions and the axial deformation of each rope, a novel automatic balance equipment for rope-type elevators (NABE-RE) is proposed in this article. Simulations based on the Simscape numerical methodology are used to verify the kinematic rationality of the proposed mechanism. The optimal structural stability of the core components is evaluated through a series of investigations based on the finite element method. Additionally, the manufactured prototypes are put through a series of comparison experiments to evaluate their tension balancing performance. The results show that the unbalance rate of the system is effectively limited to a low level, thus verifying the feasibility of the automatic tension balancing function of the proposed NABE-RE.
