按照《中长期铁路网规划》,预计到“十二五”期末,中国高速铁路达1.6万公里以上,平均每公里造价1.14亿元计算,“十二五”期间高铁的总投资约为1.875万亿元。虽然众多中国企业已经纷纷“搭上”高铁,但在高端配套领域,却严重依赖进口,被国外企业技术垄断。本文主要讲述高铁客车重要零件枕梁,加工过程中遇到的几个难点及相应的解决方案,并最终实现国产化。 According to the “Medium and Long-Term Railway Network Planning”, it is estimated that by the end of the “Twelfth Five-Year Plan” period, there will be more than 16,000 km of high-speed railways in China with an average cost of 114 million yuan per kilometer. The total investment About 1.875 trillion yuan. Although many Chinese enterprises have already “hiked” high-speed rail, they are heavily dependent on imports and are monopolized by foreign enterprises in the field of high-end facilities. This article describes the main parts of high-speed rail passenger car bolster, processing difficulties encountered in the process and the corresponding solutions, and ultimately localization.
