长沙矿山机械厂研制的J×40KB型40马力防爆低污染内燃机车,已于1984年底在开滦马家沟煤矿通过技术鉴定,已投入批量生产。现整理出该车的牵引计算方法,供参考。 一、列车组成计算 1.计算牵引矿车数量:重车下坡运行且满足40m制动距离要求的列车,其矿车数量按下式计算:式中n——矿车数量,辆; J × 40KB 40 horsepower explosion-proof and low-pollution diesel locomotive developed by Changsha Mining Machinery Factory passed the technical appraisal of Majiagou Coal Mine in Kailuan at the end of 1984 and has been put into mass production. Now sorted out the car’s traction calculation method for reference. First, the train composition calculation 1. Calculation of the number of tow car: heavy car downhill and meet the 40m braking distance requirements of the train, the number of its car by the following formula: Where n - the number of cars, vehicles;
