This paper presents a study to experimentally evaluate a new design paradigm for robotic components, with emphasis on space robotics applications. In this design paradigm, robotic components are made from embedded binary actuators and compliant mechanisms in order to reduce weight and complexity. This paper presents a series of five experiments that demonstrate the concept. These studies includ...
The dynamic performance of the trailer bogie brake system is essential for safe operation a high-speed train during braking process. In this work, we developed novel ten-degree-of-freedom (ten-DOF) dynamics model based on and tribological theories. non-linear factors including disc-pad friction wheel-rail interactions were considered. field test results demonstrated that more intense vibrations...
Wear and fatigue in rails are major contributors of rail degradation depending on operational conditions, track, characteristics of bogie type, Million Gross Tonnes (MGT), curvature, traffic type and environmental conditions. Estimation of parameter for failure models is necessary for accurate prediction of expected number of rail defects over a period of time based on MGT of traffic and operat...
This article presents the results of theoretical analysis stress-strain state industrial traction unit PE2U and PE2M frame. The was performed using finite element method in SolidWorks Simulation software. are necessary to estimate residual resource units at end their service life extend life. According requirements standards, rolling stock load-bearing constructions, these constructions should ...
Maintenance activities mostly depend on the specific conditions of individual equipment, being defined as personalized businesses. In order to improve efficiency maintenance for complex equipment in lots, thinking mass customization is used. After modular technology used generic model, product/service was divided into mandatory and optional modules, which can form multiple service solutions. Co...
Different optimal designs of bogie bolster for model 18-100 freight car are examined in the article. There is an analysis existing designs. Full-fledged fatigue tests by method specified GOST 32400-2013 carried out on stand designed dynamic strength tests. The values experimental studies were compared with calculated ones, maximum loads from 735 to 755 kN. best results observed at a load 745 kN...
The article presents the methodologies based on multi-body systems used to analyze the dynamics of rail vehicle in motion in a straight line. Study of the railway vehicles dynamics requires the creation of three mutually independent models: the model of the vehicle, the track model and a model of the wheel – rail contact. A railway vehicle model developed in the multi-body systems convention w ...
