When the speed reducer brakes the rolling stock, countless high-pressure lubrication areas will be formed between the frictional contact surface of the brake rail and the wheel, and the contact...
Due to the high humidity of the air, a water film will be formed on the wheels or the brake rail of the reducer, which will reduce the friction coefficient when the reducer is braking. Since the thick...
To achieve a win-win situation for economic development and environmental protection, so as to comprehensively promote the implementation of sustainable development strategies and policies. Key analys...
The concrete structure of the vehicle retarder is susceptible to impact damage. The mechanical properties of concrete are characterized by the large difference in strength between compression a...
Establishing a bolt parameter database The establishment of a standard parts library requires the use of a database to store part data. Two databases need to be established when designing the bolt dat...
Waveform characteristics When the spring has no defects, the ultrasonic wave is reflected inside the spring to form an ultrasonic channel in the spring. The ultrasonic wave will always propagate to ...
