【摘要】：為提升連續(xù)長大下坡路段安全水平,研究一種基于制動器溫度的縱坡設(shè)計(jì)方法.以7個(gè)典型連續(xù)長大下坡路段為研究對象,分析了下坡速度、車輛總質(zhì)量對特定連續(xù)長大下坡路段貨車制動器溫度的影響.并以車輛到達(dá)連續(xù)長大下坡終點(diǎn)的制動器溫度、制動器溫度達(dá)到200℃和260℃時(shí)距連續(xù)長大下坡起點(diǎn)的距離為特征值,分析了采用等效平均縱坡單一坡度和設(shè)置緩坡兩種展線形式對貨車制動器溫度的影響,提出了連續(xù)長大下坡路段區(qū)段劃分量化標(biāo)準(zhǔn)和縱坡設(shè)計(jì)建議.研究表明:從降低貨車制動器溫度角度考慮,連續(xù)長大下坡路段應(yīng)盡可能采用單一坡度展線,相鄰坡段采用不同縱坡坡度時(shí)坡差不宜過大,特別是下部區(qū)段.
[Abstract]:In order to improve the safety level of continuous long downhill section, a design method of longitudinal slope based on brake temperature was studied. The effects of downhill speed and total vehicle mass on the brake temperature of freight cars in certain continuous downhill sections were analyzed with seven typical continuous downhill sections as research objects. The characteristic values are the brake temperature at the end of the continuous long downhill, the distance between the brake temperature of 200 鈩，
