汽车安全气囊中整体质量检测方案(摩擦系数测试)

汽车发生严重碰撞时,装置在方向盘内和前排座椅靠背、头枕内部的安全气囊会立即打开并迅速冲入氮气,从而避免驾驶员和乘员与仪表板或前排座椅发生碰撞,减少人员伤害。但在实际生活中,却并不一定像上述情况那样理想:有可能气囊表层涂覆的干粉不够,致使表层干涩,很难立即打开;可能打开以后与人员或周围器件发生严重挤压变形,导致整体胀破,气体四溢;也有可能因为密封性太差,刚充入气体便出现泄漏…… 以上种种问题不仅意味着生产企业对产品质量的不负责任,更意味着对广大消费者生命安全的轻视。因此在生产过程中,汽车安全气囊的表面摩擦系数和袋体整体耐破性、密封性等性能指标生产企业必须严格控制。Labthink兰光为了帮助广大汽车安全气囊生产企业获得最合理精确的工艺参数,可专业提供MXD-02摩擦系数仪和LSSD-01泄漏与密封强度测试仪,来帮助检测安全气囊的表面摩擦系数、耐破强度和密封性能。 了解关于更多相关仪器信息,您可以登陆济南兰光公司网站查看具体信息或致电0531-85068566咨询。Labthink兰光期待与行业中的企事业单位增进技术交流与合作。

高速直喷柴油燃烧系统,碳烟,一氧化碳,汽车发动机中减排方法,速度场检测方案(粒子图像测速)

The current direction for Diesel combustion system development is towards homogenization, in order to reduce particulate and NOx emissions. However, a strong increase of carbon monoxide emissions (CO) is frequently noted in combination with enhanced homogenization. Therefore, the current investigation focuses on a detailed analysis of the particulate - CO trade-off using a laser-optical and multidimensional CFD investigation of the combustion process of a swirl HSDI system. The CFD methodology involves reduced kinetics for soot formation and oxidation and a three-step CO model. These models are validated by a detailed comparison to optical measurements of flow, spray penetration and the spatial distribution of soot, temperature and oxygen concentration. The results obtained show that high concentrations of CO occur as an intermediate combustion reaction product. Subsequently, CO and soot are oxidized in large areas of the combustion chamber. In part load operation, CO emissions are mainly caused by dilution effects in the early phases of combustion. However, the engine’s soot emissions are caused by insufficient oxidization. Soot generation and oxidation are found to be strongly impacted by the slight non-homogeneity of the swirl motion. The gaseous emissions are not affected by the small differences in local flow, which are outlined further in the text.
