自卸汽车侧翻事故分析实例

事故经过: 某单位一台矿内运输自卸汽车在存矿场进行卸载作业时发生倾倒事故,所幸侧翻时速度较慢,驾驶员反应灵敏,及时采取了自我防护措施,没有受伤,只是受了惊吓.车辆损失较大,两块蓄电池壳体破碎,燃油箱破裂造成燃油泄漏,举升油缸活塞杆轻度弯曲,举升油缸底座与车架连接处断裂.     

Application of a thermodynamic model with a complex chemistry to a cycle resolved knock prediction on a spark ignition optical engine

A combination of experimental and numerical methodologies is proposed for the investigation of knocking in spark ignition engines to aid in better understanding the physical and chemical processes that occur and to exploit the capabilities of a developed computational tool. The latter consists of a thermo-fluid dynamics model, which is part of an advanced 1-D fluid dynamics code for the simulation of the entire engine, and a complex chemistry model, which can be embedded into the thermo-fluid dynamics model using the same integration algorithm for the conservation equations and the reacting species. Their mutual interaction in the energy balance will be considered. The experimental activity was carried out in the combustion chamber of an optically accessible, single-cylinder P.F.I. engine equipped with a commercial head. The experimental data consisted of optical measurements correlated to the combustion and auto-ignition processes within the cylinder. The optical measurements were based on 2-D digital imaging, UV visible natural emission spectroscopy and the chemiluminescence of radical species (OH and HCO). The engine parameters, the pressure signals of the related data and optical acquisition are compared on an individual cycle basis in the simulation by running the engine at a constant speed and varying the spark advance from normal combustion to heavy knock conditions.

体验长途行车加油难

“五一”期间，笔者所在单位组织员工自备车辆到洛阳、开封、焦作等地旅游。此前对限量加油早有所闻，但未曾亲历感受。通过本次远距离行车，感受颇多。发车之前，在单位内将客车燃油箱加注满燃油（单位配有自用油库），燃油箱约容纳220L柴油，由于该车型为单位通勤客车，所以只配备单燃油箱（旅游客车一般配置双燃油箱），这也成为本次旅行中的一大缺憾。

Using a surrogate safety approach to prioritize hazardous segments in a rural highway in a developing country

Road safety is a global concern particularly in developing countries where some road sections are disproportionately more vulnerable in terms of the frequency and severity of crashes. Other than using historical crash data based reactive approaches, those sections need to be identified proactively, so that mitigation measures can be applied. Moreover, those approaches are sometimes questioned mainly due to data reliability issues in developing countries. The study reported here is aimed at highlighting the applicability of traffic conflict techniques as surrogate safety measures to identify those sections of a rural highway in a developing country, which are most likely at risk. An adapted framework is demonstrated to identify traffic conflicts using combined surrogate indicators acknowledging the limited resources and facilities in developing countries. A new model is put forwarded using a count data modelling approach. Both fixed and random parameters model derivatives have been explored as an alternative methodological approach to relate the factors affecting the number and probability of conflicts. The partial effects of individual independent variables were estimated to gain a better insight of their impact. The results show that the model can predict high risk segments in terms of probability of conflicts as well as safety risk, as well as prioritize road sections according to the likelihood of their safety level. The model provides a less expensive alternative to the collection of historical crash data in order to identify hazardous road locations or black spots on two-lane highways in developing countries.¹     

一种用汽油燃烧系统模拟发动机台架催化剂热老化的方法

采用通用汽车公司的快速老化程序RAT-A，分别在FOCAS燃烧系统及发动机上对催化剂在老化前和老化后的性能进行对比试验。结果表明，FOCAS燃烧系统能够对催化剂进行和发动机类似的老化。与发动机台架试验相比，FOCAS系统有明显的优点，如严格地控制空燃比使其变化幅度很小、空燃比稳定运行的范围宽、活动部件少及易操作等。
