Object Morphology Detection Research Based on AVR
Wheel set is an important component of bogie locomotive, one of the main factorsaffecting the safety operation of trains. Over the years, railway transportation plays animportant role in the countries’ economic development in the world,. As an importantcomponent of the wheel vehicles in the railway’s safety transportation, it occupies animportant position. The traditional detection methods [...]
Study on Integrated Method of Automobile’s Wheel Modelling and Structural Design
The most important is the hub of the vehicle load security components, its are immanent quality and reliability is not only related to vehicle and vehicle manpower-material security, also affect the vehicle driving process stability, in handling, comfort properties. This requires wheel size high accuracy, good dynamic equilibrium fatigue strength, high rigidity and elasticity, good [...]
The Research for Impact Factor Analysis and Control on Wheel and Rail Noises of High-Speed Railway
Along with the development of the economy and society, the railway is a kind of important means to get the fast development. The construction and operation of a number of high-speed passenger lines greatly accelerated the process of China’s high-speed railway. With the improvement of speed, the noise pollution increase dramatically which bring with varying [...]
Shape Optimization and Fatigue Strength Research of Wheel
Excitation frequency of wheel-rail system is increased, the service environment of the lightweight wheelsets is deteriorated, and the structure fatigue reliability issues become more and more prominent with the continuous increase of train speed. The random fatigue life prediction of the wheel is achieved by using combination method of the flexible multi-body dynamic analysis, finite [...]
Strength Analysis of Wheelset for High Speed Car Bogie
With the development of railway rolling stock towards to high speed and heavy haul, the safety and reliability of its key structures is becoming concerned. By interference fit, wheelset is made of axle and wheels. The full weight of vehicle impose on the rail through wheelset, so the wheelset plays key role while vehicle is [...]
Design of Round of the Rust on the Auto-Cleaning Machines
Wheel running gear of the train vehicles, one of the most important components. Round to ensure the quality of the rust under a fluorescent magnetic particle testing process quality, reduce leakage exploration, fault detectors, and to ensure safe transportation of great significance. In the current round of the rust machinery, not related to the rust [...]
Research on Wheel Bending Fatigue Test Machine Based on Configuration Technology
At present, the wheel manufacturers need the wheel dynamic bending fatigue test machine more, so we developed a new type of wheel dynamic bending fatigue test machine. Be based on the factors of taking into account the test accuracy and the cost of the test machine, this article synthesized all the advantages of the wheel [...]
Heat Load Analysis of Heavy-Haul Freight Car Wheel for Tread Breaking
In order to improve the transport capability of the freight car, the 25t axle load of the vehicle have been developing, the axle load of general freight car has been planning increased to 27t and the purpose freight car increased to 32.5t on the premise of the speed is raised to 120km/h. As the tread [...]
The Research of Hydraulic Turbine Runner Hydraulic Design Method and Its Internal Flow Simulation
Hydraulic Turbine is an energy-recycling appliance, which transforms the pressure energy of the fluid into the mechanical energy of the turbine through the rotating of the impeller. The hydraulic turbine can recycle as much as 70 ~ 80% of the total fluid energy, and can be used in the case of high pressure difference, and [...]
