A low-cost inertial measurement unit has been developed for accurate motion capture, allowing real-time spatial position registration (linear and angular) of the user's whole-body. For this, we implemented a dedicated circuit for 9 degrees of freedom motion sensors, composed of an accelerometer, gyroscope and a magnetometer. We also applied signal processing and data fusion algorithms to prevent the inherent drift of the position signal. This drift is known to exist during the sensor integration process and the implemented algorithms showed promising results. This system is meant to be used in two specific biomedical applications. The first one is linked to the development of a low-cost system for gait analysis of the whole-body, which can be used in home-based rehabilitation systems. The second application is related to the realtime analysis of working postures and the identification of ergonomic risk factors for musculoskeletal disorders.
This article investigates the interference fit requirements for customized dual-fit fasteners in a linear guide rail mounting application. The shaft support mount used in this study is designed to support linear guide rails and is fixed to a surface using customized dual-fit fasteners. The interference fit between the two parts of fasteners is calculated to determine the necessary friction to hold both parts attached. This study aims to optimize the frictional force in the shaft support mount attachment and investigates the effects of the fastener diameter, material, and surface roughness on the interference fit. The results of this study show that the interference fit between the two parts of the fasteners significantly affects the frictional force required to hold the shaft support mount attached to the surface. The findings of this research can be used to improve the design of linear guide rail mounting systems and provide guidance for engineers and designers when selecting customized dual-fit fasteners for similar applications.
This technical article focuses on determining the maximum power transfer capacity of spur gears mounted on shafts with spline bushes using an interference fit. Spur gears play a crucial role in power transmission systems, and the use of spline bushes with an interference fit provides enhanced stability, load distribution, and safety. The gear is mounted on the spline bush, which, in turn, is mounted on the shaft using interference fit. This arrangement ensures that in case of torque overload, the interference fit allows the spline bush to slip preventing mechanical structural failure of the transmission elements. Understanding the maximum power capacity of these gear systems is essential for ensuring reliable and efficient operation. The article provides an overview of spur gears, spline bushes, and the benefits of an interference fit. It explores the factors influencing power transmission and presents analytical methods for calculating critical parameters. A case study calculation is included to demonstrate the application of the discussed methods. Design considerations and optimization techniques for enhancing power capacity are also discussed. By determining the maximum power transfer capacity, engineers can make informed design decisions, optimize gear systems, and ensure both reliable power transmission and safety.
