Department of Mechanical Engineering is committed to provide a prestigious level of education in both Mechanical and Mechatronic disciplines leading to be awarded an accredited degree program and researching in the areas of Mechanical Engineering to publishing of such research in appropriate forums and obtaining recognition while collaborating with Sri Lankan and International Industries, provides students the excellent opportunity to graduate as an all-inclusive engineer that suits modern challengers.

Mission

To produce mechanical engineers with sound engineering knowledge and interdisciplinary problem-solving skills, social awareness and confidence required to serve emerging research and industry for sustainable development of the nation and beyond.

Laboratories and Equipments

The mechanics lab consists of machine simulation apparatuses as well as material testing apparatuses. In these labs students will be taught the working mechanisms of machines and how they are used on an industrial level. Furthermore, with the lab of the material testing apparatuses stents learn about the material properties of a material and how these properties are important in the selection of materials for engineering processes.

Thermodynamics is the study of the behavior of heat and thermal energy. Energy is the ability to bring about change or to do work. Historically, thermodynamics originated as a result of man’s endeavor to convert heat into work. In the Thermodynamic Laboratory we observe different type of energy transferring process and how energy is being loss to the environment through Conduction, Convection & Radiation also the behavioral patterns of pressure due to the sudden changes in temperature will be methodically observed. In addition to that working mechanism of a Heat engine, Basic refrigeration and Advance refrigeration systems, steam cycles & the relevant theories for each section will be thoroughly covered. To get give the hands-on experience for our students, an experienced laboratory professional and the top quality personal protective equipment will be provided to the students to reach their maximum potential.

Equipped with a four ton hoist among other essential equipment, the Automobile Laboratory houses two vehicles - including a custom built fully Electric Three-wheeler, test rigs, an assortment of automobile parts and an array of sophisticated as well as conventional tools, which allow students to gain hands-on experience and practical insights into the working principles, mechanisms as well as dismantling of key automotive elements. The dedicated vehicles allow a multitude of experiments to be conducted including Noise and Vibration testing. Custom built apparatus designed and fabricated by our expert staff, including a Bush Testing rig and Clutch mechanism apparatus, among others, allow instructors to precisely convey the intended objectives of laboratory exercises. Fostering independent growth, the Auto Lab welcomes individual research while harboring many student projects and the Formula Student initiative, under the watchful guidance of our expert resident Auto Technician and academic staff, enabling students to witness the practical application of theoretical concepts and enrich themselves with field experience.

The Mechanical Workshop consists of various machines including lathe, drilling, milling, welding machines and all the other basic tools that we require during a workshop session. During a workshop practical, students will be taught the working mechanisms of machines and tools, their safety measures and also about the industrial level applications. Our workshop provides a safe environment for all the students under the guidance of the academic staff.

The automation laboratory consists of modern industrial automation devices. The hands-on lab sessions designed to enable students to tackle real-world industrial automation tasks and problems

With the use of various types of valves, actuators and sensors, the lab provides hands on knowledge on developing Pneumatic, Electro-Pneumatic, Hydraulic systems. Industrial controls implemented through the latest Programmable Logic Controllers (PLC) and Programmable Automation Controllers (PAC). Human Machine Interfaces (HMI) and Supervisory Control and Data Acquisition (SCADA) used to create a bridge between the industrial system and the human operator.

In addition, the lab provides a miniature conveyor system to simulate an object sorting mechanism. The system consists of a conveyor driven by a DC motor, a photoelectric sensor to detect the type of object and pneumatic pistons for object ejection. This setup provides a platform to build a realistic industrial system for a given situation and allows students to think more practically.

Message from the Head of the Department

The mission of the department is to produce mechanical engineers with sound engineering knowledge and skills to meet today’s aspirations and demands. The mechanical engineers have an important role to play in overcoming numerous challenges faced by our country.  We are committed to providing a world-class education for the future generation of mechanical engineers who will undertake the ardent task of finding sustainable solutions to greatest engineering challenges.

Mechanical engineering is one of the oldest fields of engineering. Nevertheless, we have identified latest trends and offer a modern curricula to produce graduates with the required knowledge and skillsets.

The department offers a Bachelor of Science Honours Degree in Mechanical Engineering. We have identified that mechatronic engineering as an emerging area in recent times. All mechanical systems have integrated electronic systems for improving its performance and autonomous operation. Hence we offer a state of the art Bachelor of Science Honours Degree in Mechanical Engineering specialized in Mechatronic Engineering.

We have designed the curricula to facilitate the modern concept of student centered learning. The delivery of modules include lectures, tutorials, labs and project work. During the program, students are required to undergo a compulsory period of industrial training. The curricula meets the requirements of local and international professional and accreditation bodies.

The department has a well-qualified staff consisting of professors, senior lectures, lecturers and instructors involved in the delivery of the programs. We also have visiting lectures who are experienced professionals to share perspectives from the industry. Laboratories are an indispensable part of the delivery of a Mechanical Engineering program. The department has a mechanical workshop and eight labs covering all major areas of mechanical engineering.

Over the years the department has built a broad network of partnerships with local and foreign industry and other organizations. The Bentley Computer Aided Engineering Unit established with Bentley Motors UK is the result of one such partnership. Our staff members are also involved in numerous research projects to find solutions to problems we face in modern times. We are also involved in internationally sponsored projects collaborating with other local and foreign universities.
