Crashworthiness simulation and improvement design of auto-body based on finite element mehtod

One developing commercial vehicle was simulated on crashworthiness using the nonlinear finite element method. The deformation of the auto-body, the movement of the steering wheel and the dynamic responses of the occupant at the initial velocity of 50 km/h were studied. The results show that the design of the vehicle could be improved on structure and material. The frontal longitudinal beam, the main energy-absorbing part of the auto-body, was optimized on structure. The data of the simulation predict that the hinge of the engine hood would fracture during the crash. The failure of the engine hood hinge would be a danger to both the driver and passengers. Then the problem was solved by changing the engine hood and hinge on structure and material. Simulation results also show that applying new material and new manufacture techniques could improve the crashworthiness of the vehicle greatly. These improvement methods are valuable to the virtual design of vehicles.     

面向国家标准的汽车转向机构安全性仿真

国家标准《防止汽车转向机构对驾驶员伤害的规定》中规定了防止转向机构对驾驶员构成伤害的技术要求和当汽车受正面撞击时转向盘向后窜动的试验方法，转向盘遭受撞周时吸收能量的试验方法，本文以某车型及其转向机构为研究对象建立有限元模型，按国家标准规定的试验条件对两项技术要求进行计算机仿真，仿真结果与试验结果吻合，因此利用仿真技术对评价汽车转向机构碰撞安全性具有一定的指导意义。     

关于事业单位工会维权途径与机制的探究

维权机制的建立是工会基本职责的履行,是做好维权工作的基本保证。在维权机制建设中,事业单位工会进行有益的探索将会起到重要的现实作用。但是当前维权机制的建设中存在的问题很多,具体的表现为重数量,轻质;重形式,轻内容;工会维权机制还没有真正有效的运转起来,部分事业单位的工会维权机制却已经成了"花架子"。为了提高事业单位工会维权实效,建立和完善事业单位工会维权机制,切实做到维护广大职工的基本权益,就要对这些问题进行分析,找到问题的解决对策。本文主要对事业单位的工会维权途径和机制的建立进行分析,以求更好地维护广大职工的基本利益。
