impact speed meaning in Chinese
冲击速度
碰撞速度
碰撞速率
Examples
- Determination of the impact speed of eroded particles in a slurry medium - containing quartz sand for the erosive - corrosive wear
砂浆冲刷腐蚀磨损介质中粒子冲击速度的确定 - Most current earth - penetrating missiles achieve their impact speeds ? around 450 meters a second ? simply from the force of gravity
目前最新的钻地飞弹完全依靠重力获得冲击速度（约为每秒450公尺） 。 - A parameter study on dynamics of the car and biomechanics response of occupant was carried out in terms of initial impact speed and impact angle of the car
通过改变不同的仿真参数(碰撞条件) ，研究碰撞中汽车的动态响应和乘员的生物力学响应特性。 - A head - on collision involving two vehicles each moving at only 25 km h produces an impact speed of 50 km h - the same as falling head first from the third floor window of a building . the following summarise the main legal requirements for wearing seat belts
如果两辆时速25公里的汽车迎头相撞，产生的冲力会高达时速50公里，相等于一个人从四楼窗口堕下而头部首先著地的冲力。 - The effect of car body elastic vibration on the ride comfort is analyzed . the ride comfort and acceleration responses of the car system with rigid car body model or elastic car body model are studied and compared . finally by using ansys / ls - dyna software , the finite element impact models of car body with a rigid wall have been set up , then the displacement , velocity , acceleration and energy variation of the car body are analyzed and compared for before and after lightening cases under the condition of impact speed 5 . 8m / s and 11 . 8m / s
本文利用ansys软件建立了25k硬卧客车车体轻量化前后的有限元模型，计算了车体的强度、刚度和模态，并对轻量化前后的车体作了对比分析；然后，用nucars动力学分析软件建立了25k硬卧客车系统的数学模型，分析了弹性振动对平稳性的影响，并对刚性车体和轻量化前后的弹性车体对平稳性和加速度响应的影响作了对比分析；最后用ansys / ls - dyna软件建立了25k硬卧客车车体轻量化前后的动态显式有限元模型，分别在5 . 8m / s和11 . 8m / s的速度下碰撞刚性墙，得到了车体的相对位移、速度、加速度和能量的变化过程，并作了对比分析。
