浅谈汽车类学生跟岗实习日常管理工作 ——以四川信息职业技术学院为例

四川信息职业技术学院汽车类学生根据人才培养方案中的教学计划要求,在校期间的学习过程中,需要深入到企业中进行为期一个月的跟岗实习,利用实习的机会可以加强学生的综合素养。但是最近几年学生在实习的过程中也产生了很多的问题:例如缺少职业素养、不能较好地服从企业管理等问题。文章主要从企业、学校、指导老师、学生等层面来浅析学生跟岗实习日常管理工作。通过实践取得了良好的预期效果,愿为高职院校圆满地完成汽车类学生跟岗实习及管理工作提供借鉴。     

汽车灯具中灯体嵌件后压入工艺研究

介绍了汽车灯具中灯体嵌件后压入工艺中冷、热2种压入方式的工艺过程及特点,给出了灯体后压入嵌件和底孔的尺寸及设计方法.试验结果表明,与嵌件直接注塑嵌入成型相比,嵌件后压入工艺具有模具结构简单、灯体报废少、嵌件定位精度准确等优点,可保证灯体加工和装配的质量要求.

Improving the fatigue life of large offshore foundations

Offshore foundations are subject to fatigue due to wind and wave loads during their lifetime. Post-weld treatment is a group of techniques well known to improve the fatigue life. This study investigates how this is applicable for large structures, i.e. a 2.4 meter jacket T-node. A large scale empirical study was performed and results were obtained from a SN-diagram based on three repetitions and supported by a theoretical background. The as welded samples performed as expected and on the safe side of the category 56 line. Unexpectedly, the burr grinded samples showed no improvement and had an evidently larger variance. Both ultrasonic impact treatment and especially pneumatic impact treatment showed improvements, but did not reach the expected category 125 line. The results were substantiated with strain-gauge measurements for hot spot analysis. The obtained results on fatigue life improvements give rise to apply post weld treatment in an industrial scale for offshore construction. However, it also brings up the discussion of the necessity to redesign structures in order to automate the treatment in a cost efficient manner.
