“…Now, following the guidelines proposed by the mechatronic design methodology, the simulation of static loads was performed to verify that each proposed mechanism did not suffer tension failures when applying a force, as shown in Table 3 . For this purpose, the SolidWorks Simulation software was used, which estimates the Von Mises stress, a scalar that can indicate a good design for ductile materials, such as those used in [ 28 ].…”

Injuries in the elbow area, such as lateral and medial epicondylitis, are the leading causes of consultation with health specialists. Therefore, this research proposes the mechatronic design of an orthosis with a graphic interface that supports professionals in the rehabilitation of the elbow joint through the execution of flexion–extension and pronation–supination movements. For the development of the rehabilitation prototype, mechatronic design, co-design, and IDEF0 methodologies are used, performing activities such as actuator characterization, simulations, and modeling, among others. Through the execution of a case study in a real environment, the device was validated, where the results suggest a functional and workable prototype that supports the treatment of pathologies in the elbow area through the execution of the mentioned movements, supposing that this is a low-cost alternative with elements to improve, such as the industrial design and new functionalities. The developed proposal shows potential as an economical product that health professionals can use. However, some limitations related to the design and functionalities in the application domain were identified.

“…Despite the advanced levels this technology has achieved recently, the efficiency and high initial investment costs required remain a considerable challenge for investors, researchers, and other stakeholders in this technology. In the last decade, the use of single and dual-axis tracking systems has played an important role in terms of gaining high amounts of energy, and much research has been conducted to analyse and design various types of solar trackers [1][2][3][4][5]. These studies found that the selfweight of the structure, and wind loads, are the primary forces that affect its stability directly, and hence such structures should be designed and tested to a high level.…”

The use of advanced technologies to increase the amount of solar irradiance received, using solar tracking systems, is an important development that will enhance the efficiency of solar modules' ability to produce energy. However, solar trackers are vulnerable to failure or collapse, due to aerodynamic loads. This study analyses a dual-axis tracking model, using finite elements numerical modelling, to assess its structural stability and fatigue under static and cyclic loads. A rectangular solar tracker, with an area of 27.4 m² is investigated, using COMSOL Multiphysics 5.3 software. The results demonstrate that the maximum von Mises stress obtained is 92.51 MPa, which is less than the yield stress (200 MPa), and that the resulting safety value is 2.16. The maximum settlement obtained is 19 mm. In addition, the maximum usage fatigue factor obtained is 0.046. The study therefore concludes that the solar tracker structure satisfies the design requirements of the stability and fatigue criteria. Moreover, it concludes the ground concerned is stable, and exhibits only a slight amount of settlement that falls within the acceptable range, according to geotechnical engineering design.

Modeling and simulation of mechanical structures in development phase are fundamental to optimize and improve the stability and reliability of the final product as well as to reduce the cost of prototyping and testing. Wind turbines are subject to critical loading to the centrifugal force due to wind speed and gravitational force. The present study discusses three-dimensional numerical simulations of combined Darrieus-Savonius wind turbine D-SWT for applications in urban and isolated areas for lighting, pumping water, etc. The Darrieus turbine is used to produce wind power and the Savonius rotor to start the system. Finite Element Analysis (FEA) using SolidWorks 2015 is employed to generate the geometry of the structure and SolidWorks Simulation to investigate the stability and reliability static on the structure of the D-WST built by two types of material of the blade Galvanized Steel (GS) and Aluminum alloys 1060-H18 (ALU). Mechanical parameter of the structure are calculated for critical loading conditions, including the gravity and wind pressure loading due to the wind speed of 23m/s. Simulations results indicate no structural failure is predicted for all components of the D-SWT for both materials used according to Von Mises criterion stresses and the factors of safety of the most fragile material are greater than (the unity) 1. The maximum displacements found (3.84 & 6.81mm), occurred at the tip blades (free ends levels). These displacements are accepted relatively to the structure size.
