ABOUT THE COURSE:

The course is designed as a fundamental undergraduate/postgraduate course to support motivated students willing to achieve excellence in their scientific and engineering research pursuits in the area of hydraulics. The course will also be beneficial to the researchers and industry personnel working in the relevant field. Each module comprises theoretical lectures that lay the foundation, component/system demonstrations, design aspects, and home assignments to enhance the penetration of the core syllabus and would finally end with an end-of-course exam. In addition to formal lectures, the course would include lab demonstrations to explain further the concepts taught through the theories. This will help students to have enough exposure to pursue the subject further as professionals in the industry or as students of higher education in top universities in India or abroad. The course focuses on making students industry-ready, enabling them to design and develop low-cost automation circuits for industrial applications and develop innovative design solutions to cater to the demands of any modern industry where skilled manpower is required to innovate and maintain the existing setups. The broad objectives of the course are summarized as:

• To design fluid power circuits with standard symbols.

• To demonstrate working principles and constructional details of major components used in Fluid Power Systems.

• To understand and analyze system components and drives.

• To develop the dynamic model of the hydraulic systems and their control.
