Braham教授在印度新德里理工大学获得机械工程硕士学位和摩擦学博士学位,于1985年成为日本东京工业大学的访问研究员,1998年至2000年间为千叶工业大学的日本学术振兴会(JSPS)会员,2002年获得瑞典吕勒奥工业大学机械元件研究所教授职位,现任清华大学摩擦学国家重点实验室杰出兼职教授,同时还担任几家摩擦学(如Friction一区)刊物的客座编辑,曾在各种国际摩擦学会议上被邀请参加会议。Braham教授在学术和工业领域都有超过41年的研发经验,研究和教学活动与高温摩擦学、材料和润滑剂的摩擦学、固体润滑剂/自润滑涂层、边界润滑、机械部件的摩擦学(轴承、齿轮和密封)以及摩擦磨损相关。其在各种国际期刊中发表论文200余篇,并出版专著。此外,教授已成功完成100多个工业合同的研发任务。
在讲座中,Braham教授先介绍了吕奥勒工业大学以及其所在机械研究所的情况。吕勒奥理工大学成立于1971年,其机械研究所及摩擦学研究在领域内占有重要地位。
摩擦学,即研究相对运动或有相对运动趋势的相互作用表面间的摩擦、润滑和磨损,及其三者间相互关系的学科。摩擦学涉及的领域很广泛,影响摩擦界面性能的因素多且复杂,涉及物理、数学、材料等多个学科。
Braham教授的许多研究基于工业应用背景,通过追求摩擦学的最优方案来减少摩擦和磨损,以达到降低成本和能耗,并且改善产品质量。他着重介绍了他的几项研究项目,例如超高强度钢热压成型中的摩擦磨损问题以及润滑涂层开发;车辆离合器中的摩擦学问题,发动机气缸套中的摩擦学等。在前沿研究分享中,他介绍了用于水润滑的多尺度聚合物复合材料等。
In the lecture, Prof.Braham first introduced the Luleå University of Technology(LUT) and the Mechanical Research Institute he worked. The mechanical research institute and its' tribology research in LUT have played an essential role in the field.
Tribology, a discipline that studies friction, lubrication, and wear between relative motion or interactive surfaces with relative motion trends, and the relationship among them. Tribology involves a wide range of fields. Many complex factors affect the performance of friction interface, including physics, mathematics, materials, etc.
Most of his researches are based on the industrial application. By pursuing the optimal scheme in tribology to reduce friction and wear, he aims to reduce the cost and energy consumption while improving product quality. He focuses on several of his projects, such as friction and wear problems in the hot pressing of ultra-high-strength steel and the development of lubricating coatings; Tribology in vehicle clutch; Tribology in engine cylinder liner, etc. On cutting-edge researches, prof.Braham introduces the multiscale polymer composites for water lubricated tribological contacts.
