冷轧运卷小车是负责钢卷运输的关键工序设备,其液压系统设计不仅需要满足钢卷大举升力、多级升降速度、高度等工艺参数,而且要求运行平稳、高安全性,否则会带来故障频发带甚至于重大安全事故。本文通过理论计算、原理图设计、元件选型,完成了运卷小车液压系统设计,并通过AMEsim仿真软件对设计进行了校核及优化,结果表明本设计可以满足生产工艺需求及现场安全要求。 相似文献

1.设备概况钢卷小车是西德引进的设备,安装在卷取机与大链子运输机之间,担负着将已酸洗好的钢卷从卷取机上卸下来,并运送到链子运输机上去的任务。它是酸洗机组的重要设备,原设计为机械传动。走行机构由电机经立式行星减速机和螺旋锥齿轮传动到车轮上。这种结构比较复杂,而且太阳轮轴颈强度和轮齿的弯曲强度不够,以及行星轮的布置不合理等缺点。因此在投料试车阶段,2号钢卷小车就发生过太阳轮和行星轮齿部被磨坏,轴被折断,造成 相似文献

In today's business environment people can no longer afford to be 'out of touch' when they are away from the office, with the result, the car has become a mobile office for many workers. The aims of this study were * to review current technology in the mobile office, * to determine problems of office working in the car, * to offer design solutions. Case studies gained an insight into working practices and problems in the car. Diaries quantified the types and amounts of work done in the car and an interview survey measured the extent of mobile office technology implemented into cars, problems relating to working in the car and some potential solutions. People do experience problems trying to do office work in their car. These problems include lack of space, lack of storage, nowhere flat to rest work on, inadequate temperature control in the car and poor communication facilities. 相似文献

Due to the high energy absorption capacity at constant compressive stress level, cellular metals may be used as crash‐energy‐absorbing elements in autobody structures or car components, e.g., car seats. Modern car seats do not only have a high technical functionality, like electronic positioning, heating, and ventilation systems; in the case of a crash they must protect the passenger. The present paper deals with an analysis of potentially suitable cellular metals for integration in car seats. By means of different quasi‐static tests, i.e., compression, tensile, shear, and bending testing of several candidate metal foams and foam sandwich structures, the general material properties, the damage behavior and the reproducibility of mechanical data are tested. The results, which include optical 3D strain distribution measurements of the chosen cellular metals during quasi‐static testing, are implemented in the engineering design of structural car seat components and finite element calculations to simulate the crash behavior. Objective of the work is the derivation of robust and reliable mechanical testing procedures and standards as well as an improved understanding of the damage mechanisms of cellular metals under different loading conditions to finally derive design guidelines for cellular metals. 相似文献
