根据功等于力与距离的乘积的定理,减速顶的制动功可作如下表示: W=integral_1 (f(1)dl) 显然,加大距离1可提高制动功,而1只能随减速顶安装高度H的增高而加大,因此,提高制动功的有效途径之一是把减速顶安装高度H增高。但是,H的增高受到编组场内线路限界以及车轮与减速顶接触关系的限制,一般允许的极限是75mm。那么,减速顶安装高度H的值 According to the theorem of work equal to the product of force and distance, the braking work of the deceleration top can be expressed as follows: W = integral_1 (f (1) dl) Obviously, increasing the distance 1 can improve the braking work, One of the most effective ways to increase the braking power is to increase the decelerating roof mounting height H. However, the increase of H is limited by the line limits in the field of assembly and the contact relationship between the wheels and the decelerating top. The allowable limit is generally 75mm. Then, the decelerating top installs the value of height H.
