A platen assembly is an integral part of a railway line. The track referred to here includes many components. As a whole engineering structure, the track is laid on the subgrade, plays the guiding role of the train running, and directly bears the huge pressure of the locomotive and vehicle and its load. Under the dynamic action of the train operation, its various components must have sufficient strength and stability to ensure the train to operate safely, smoothly and without interruption according to the prescribed Z high speed. In the annual vehicle procurement of the Ministry of Railways, in addition to the new vehicle demand brought by the new mileage, there is also a large part of the vehicle replacement demand. Railway linking piece for several years, rapid development in the backdrop of the railway linking piece speed and overloading, in order to achieve the hundreds of kilometers per hour or dozens of tons of overloading goal, must equipment can meet the needs of high-speed overload, safe and reliable and high quality rail linking piece, it will directly to speed up the demand for high technical content of vehicle accessories, There's a lot of room for new generation products and technologies. Since the launch of the railway Leap-forward development plan eight years ago, China's investment in railway construction has seen a significant increase. Seven years ago, the annual investment in railway infrastructure and in the purchase of rolling stock doubled compared with five years ago. By six years ago, the annual investment in railway fixed assets in China reached more than two hundred billion yuan. Railway accessories are the components of railway lines, here refers to the track including rail, sleeper, connecting parts, road bed, anti-climbing equipment, rail support and turnout, etc. As a whole engineering structure, the track is laid on the subgrade, plays the guiding role of the train running, and directly bears the huge pressure of the locomotive and vehicle and its load. Under the dynamic action of the train operation, its various components must have sufficient strength and stability to ensure the train to operate safely, smoothly and without interruption according to the prescribed Z high speed.
