動(dòng)車組車輪踏面的檢定方法及裝置研究

【摘要】動(dòng)車組車輪踏面是列車行駛的核心部件，如何精準(zhǔn)及時(shí)對(duì)動(dòng)車組車輪踏面進(jìn)行檢定，不僅關(guān)乎乘客乘車的舒適度，也可以保障列車的運(yùn)行安全。本文介紹了一種動(dòng)車組車輪踏面檢定裝置，并且將其應(yīng)用于實(shí)踐中，同時(shí)也探討了對(duì)該檢定裝置進(jìn)行計(jì)量溯源的方法。

【關(guān)鍵詞】車輪踏面；檢定裝置；計(jì)量溯源

Abstract： The wheel tread of Multiple unit is the core component of train operation. How to accurately and timely verify the wheel tread of Multiple unit is not only related to the comfort of passengers， but also can ensure the safety of train operation. This paper introduces a kind of verification device for wheel tread of Multiple unit， and applies it in practice. At the same time， it also discusses the method of metrological traceability of the verification device.

Key words： wheel tread； verification device； metrological traceability

0引言

隨著我國(guó)軌道交通的發(fā)展，鐵路設(shè)計(jì)速度和荷載重量持續(xù)上升，在保證線路提速和高速化過程中，又對(duì)高速軌道車輛的輪軌系統(tǒng)的安全性、可靠性、耐久性提出了更高的要求。（剩余4192字）
