机车撒沙与提高黏着牵引力关系试验研究

Research on Relationship between Locomotive Sanding and Improving Adhesion Traction Force

在轮轨低黏着状态时可采用撒沙提高机车黏着牵引力,针对撒沙与提高机车黏着牵引力关系开展了试验研究,分析不同撒沙工况下的机车黏着牵引力提高情况,提出了机车撒沙系统的优化方案。

Sanding can improve locomotive adhesion traction in low wheel-rail adhesion status. In this paper, tests and research were carried out for analyzing the relationship between locomotive sanding and improving adhesion traction force. Improving adhesion effect was compared and analyzed under different sanding conditions. In the end of the paper, an optimization scheme of the sanding system was proposed.
