摘要
针对B0+B0-B0+B0轴式八轴机车不同的牵引方案,在定义了名义牵引高、过渡牵引高和等效牵引高的基础上,进行了轴重转移的计算分析。分析结果表明:不管B0+B0-B0+B0轴式八轴机车的悬挂采用什么方案,机车的最佳牵引高总是接近轨面的,采用水平牵引装置很难达到最佳的黏着利用率。通过采用斜牵引杆结构,使机车的名义牵引高达到最佳牵引高,就能获得较高的黏着利用率。分析了斜牵引杆结构的名义牵引高和倾斜角对机车黏着利用率的影响,给B0+B0-B0+B0轴式八轴机车牵引机构的设计提供了理论依据。
The load transfer of B0+B0-B0+B0 locomotive with different traction schemes was calculated,basing on the definition of nominal and transitional and equivalent traction height.The analysis results show that whichever suspension method of B0+B0-B0+B0 locomotive is adopted,the optimum traction height is always near the rail level.So it is hard to realize optimum adhesion availability if the horizontal traction device is taken.A higher adhesion availability can be reached as long as the slope drag bar device is used to make the nominal traction height equal the optimum traction height.In the paper,the influence of the nominal traction height and the slope angle on optimum adhesion availability of the locomotive is also analysed for the purpose to offer a theoretical base for the traction device design of B0+B0-B0+B0 locomotive.
