normal impact meaning in English
正碰撞
Examples
- High chromium cast iron has higher erosion resistance at lower impact angle , while the erosion resistance is worse for the lower toughness at normal impact
高铬铸铁在低角冲蚀时有较高的耐冲蚀性，但高角冲蚀时由于脆性大，易崩裂。 - For a impact process with a normal impact velocity , the control equation for rkpm was deduced based on a small strain and incremental elasto - plastic constitutive law
针对冲击速度较低的情况，假设冲击过程为小应变，并引入弹塑性增量本构关系，推导出冲击过程的再生核质点法计算控制方程。 - The dominant parameters on the anti - erosion proportion of materials are rigidity and intensity at lower impact angle , while the main parameter is toughness at normal impact . the ni - based alloy coating and ni - based alloy / sic coating have been obtained by laser cladding
决定材料抗低角冲蚀磨损性能的主要因素是硬度和强度，抗高角度冲蚀能力取决于材料的韧性，在实际应用中需要综合考虑这几个因素。 - Compared with any vibrating systems involving normal impacts , an oblique - impact vibrating system features not only the non - smooth characteristic of impacts , but also complicated dynamics owing to the relative tangential velocity and corresponding friction between two colliding objects
斜碰撞振动系统不但具有正碰撞振动系统力学状态的非光滑特性，还由于相对切向速度和摩擦引起碰撞物体的切向变形，因而具有更大的研究难度。 - But the noise made when the door is closed is far beyond national correlative standards , and make serious noise pollution . the article put emphases on the mechanize of the electric control door through experiments on the spot and emulation of computer , then advance that the root of noise is that the design has defects . the safe close of the door is depended on the impulsion of door normal impacts
本文密切关注了这种与大众生活相关的研究课题，通过实测实验和计算机系统仿真，重点研究了电控门工作的机理，提出了电控门噪音产生的根源是设计存在重大缺陷?电控门的安全闭合必须依靠门体正撞产生的冲击力，并且没有相关降噪措施，必然在使用造成巨大噪音的结果。
