制动初速度 meaning in English

initial eed of braking
initial speed of braking

Initial speed of braking
制动初速度
The calculating formulas show that braking distance depends on initial braking speed , road dragging coefficient , mad slope grade , braking force increasing time ; and nothing to do with total mass of crane
计算公式表明：决定汽车起重机制动距离的主要因素是制动初速度、路面阻力系数、道路坡度和制动力增加时间；汽车起重机总质量与制动距离无直接关系。
The measuring principle of brake acceleration , brake speed , height of vehicle gravity center , pitching inertia of sprung mass and efficiency of suspension anti - pitching are also theoretically discussed to provide new methods for vehicle test research
进一步说明了该系统在车辆制动减速度、制动初速度、整车质心高度、簧上质量纵向转动惯量及悬架抗制动点头率的测试或计算方法。
