Analysis and research on dynamic characteristics of railwayway vehicle braking system

The creep phenomenon will inevitably occur in the course of railway vehicles traveling. By solving the creep mathematical model, the relationship among wheel-railway adhesion coefficient, vehicle speed and creep rate is obtained. On this basis, the mathematical model of ABS and AMESim simulation model are established, and the simulation and analysis are completed under the conditions of track drying and wetting. The temperature field of disc brake is analyzed based on ABAQUS.

Design of mobile battery intelligent control system

According to the working environment and conditions of mobile battery, an intelligent control system is proposed. The system can complete the detection, communication, display, early warning and storage of battery-related information to ensure the stability of the working status of each battery. The system is based on single chip computer and has high performance-price ratio. In terms of function, the designed system has many functional modules, besides basic data detection, it can also realize fault diagnosis, storage and early warning, with high efficiency.

Strength and modal analysis of aviation turbine based on ansys

Turbine is an important component of aero-engine. Once a fault occurs, especially when the load exceeds the yield strength, the turbocharger will be damaged in a very short time. Therefore, the structural reliability analysis of turbocharger becomes more and more important. A simplified turbine model is established by Catia. The static strength of the model is analyzed based on ANSYS Workbench finite element analysis software. The distribution of stress and deformation is obtained, and the relationship between rotational speed and maximum stress is studied.

A literature review on natural fibers, its properties and influence of water absorption on mechanical properties of composites

Natural fibers composites are low-cost fibers with high specific properties, low density and eco-friendly. The development of advanced bio composite materials made is increasing in the world. It will be an alternative way to develop the bio-composites which can be particularly used for daily needs of common people whether it is house hold furniture, house and light weight car components and other equipment. This effort to develop bio-composite materials with improved performance for global applications is an ongoing process.

System engineering as a deployable enterprise system generation tool

This paper verifies the effectiveness of system engineering by its impacts towards enterprise system generation. An industrial case studies is presented about IBM adopted a model-driven engineering method to determine intentional services that meet business goals. It aims to extend the understanding of a specific method of system engineering- Service Oriented Architecture (SOA), with its flexible integration of business process and effective simplification of generation framework.

A universal programming platform by extending xml

XML is everywhere: Data Integration, File configuration and Interface definition are areas where XML is intensively present. We may define rules, constraints and configuration settings, or specify graphical interfaces, export data and define rules. This markup language allows the extensibility of any data specification, graphical interface design, or settings storage in an easy and flexible way, which allowed a wide usage of XML in the industry community. Programmers write programs using a learned syntax that depends of a specific language.

Security threats in electronic learning

Technological advances have made e-learning an increasingly central delivery system enhancing teaching and learning processes. Unlike face-to-face methods of teaching, which depend on physical structures, e-learning provides a potentially better alternative to face-to-face learning and makes learning easily accessible. With e-learning, education can be facilitated from virtually anywhere and at any time because of the convenience and affordability of the new technology. At the same time, however, new technology has introduced platforms that attract illegal activity.

Control system design of three-servo packing machine

Aiming at the shortcomings of packaging machine, such as slow packing speed, limited packing precision and low intelligent level, a three-servo intelligent high-speed packaging machine was designed and developed. Three-servo packaging machine is one of the most important equipment in food and material packaging industry. Its control effect and reliability have a key impact on the efficient completion of packaging process.

Students e-learning acceptance in developing countries: liberia

The rapid advances in technology and the changes these advances have brought to people’s lives have led to increased study of technology acceptance. Studies have shown that a factor such as behavioral intention affects college students’ e-based learning acceptance. Despite the substantial amount of knowledge on the acceptance of technology, there was a gap in knowledge regarding the veracity of TAM undeveloped countries.

Smart connected home

Technical development in Industry 4.0 offer the humanity, the assumption for living a simple yet advance life maintains on increasing. "SMART Connected" word is ending up being preferred nowadays by most of us. We live in an interesting time where increasingly more daily items, objects are becoming SMART! All objects have sensing units and can communicate to various other objects and also can supply control to more objects. The Internet of Things (IoT), is upon us in a significant way and also designers are rapidly designing new gadgets that enhance our lives.
