Research in Engineering Design at Aalto University focuses primarily in two fields: product development and mechatronics.
The research interest in product development consists of product development methods, including conceptual design, modularisation, integrated product development processes and industrial design and design for manufacturing. Aalto University Design Factory serves as an essential research environment for our product development work.
Mechatronics represents modern machine technology as a multidisciplinary field of science, including mechanical engineering with electronics and computer control in the design and manufacture of industrial products. The aim in mechatronics design is to enhance the performance of machines, improve their price-performance ratio and increase functionality. Main research interests in mechatronics include vehicle dynamics in Arctic conditions, hybridisation of mobile machines, industrial internet-connected machines, rotating machinery, tribology and integrated fluid power systems. With respect to integrated fluid power systems, the main research interests are digital hydraulics, magnetorheological actuators, vibration control technology and wave energy applications.
Biotribology research studies the properties and development of prosthetic joints.
The wear of prosthetic joints, especially total hip and knee prostheses, poses a significant clinical problem. The wear products of implants cause adverse tissue reactions, which may lead to substantial loss of bone around the implant and consequently the loosening of the fixation. This requires a revision operation, in which the loose implant is replaced with a revision prosthesis. Revision operations are complicated and expensive, however, and their results are often poor.
Research aims to improve the tribological evaluation methods for prosthetic joints and their materials. Two examples of this activity are the design, building and validation of the 12-station anatomic hip joint simulator HUT-4 and the 100-station pin-on-disk hip wear simulator Super-CTPOD. These two simulators are now commercially available from Phoenix Tribology Ltd (TE 86 and TE 87).
The latest additions to the selection of test devices are RandomPOD, a 16-station, computer-controlled, servo-electric pin-on-disk wear simulator that can be programmed to produce virtually any type of motion and load, even random; and HF-CTPOD, a 3-station, dual motion pin-on-disk device for accelerated wear testing.
The study of tribology (friction, wear and lubrication) of orthopaedic biomaterials started in the Laboratory of Machine Design in 1987. The principal source of funding has been the Academy of Finland. In addition, contract studies have been conducted for the orthopaedic industry and for the National Agency for Medicines.
Integrated fluid power research focuses on energy efficiency, covering a broad spectrum in the areas of control, component and systems development and energy management. Topics of interest include digital hydraulic valve development and new manufacturing methods, hybrid systems and autonomous actuators and energy management focused on regenerative systems in general, using external and renewable energy, pressure accumulators, pumps and compressors, and also benefitting from new manufacturing technologies. As fluid power technology is tightly integrated with other technologies, such as electronics, mechanics and thermodynamics, these aspects are also considered in most research.
Digital hydraulics enables realising hydraulic systems that are robust, more fault-tolerant, have better controllability and operational characteristics and are also more cost- and energy-efficient than the hydraulic systems commonly used today. Research focuses on valve development and new manufacturing methods. Due to its advantages, digital hydraulics is expected to seize the hydraulics market in the near future.
Hybrid systems enable using different kinds of energy sources, thus improving their energy economics. The research focuses on autonomous actuators, which are expected to replace some of the central hydraulic systems in various machines due to their clear advantages in e.g. self-sufficiency, fewer design constraints, an optimised selection of components and better maintainability.
Energy management research is focused on regenerative systems in general, using external and renewable energy, pressure accumulators, pumps and compressors, and also exploiting new manufacturing technologies. The market for energy-efficient systems is increasing due to the rapid increase in global energy usage and risks posed by global warming.
Industrial internet research focuses on applying and developing of digital methods to improve the efficiency and quality in both product design and product use. Essential elements include the identification of new development and application potential and competitive advantages offered by IoT including 5G applications in II. Digital disruption of industry is recognised as a common future challenge and possibility. Aalto Industrial Internet Campus is the primary research environment.
Mechatronic machine systems research covers a wide range of mechatronic machines, focusing on two major areas of interest.
Mechatronic applications in vehicles include vehicle dynamics in Arctic conditions and the electric powertrains of mobile machines. In electric powertrain research, the focus is on heavy vehicle powertrains and robust design methods. These design methods aim at high overall performance and energy efficiency, taking into account driving cycles and other loads.
Industrial internet provides a new source of data for research and further improvement of the machines. For instance, electric vehicle research uses data measured on-line during machine operation. On-line data collection makes it possible to study machines in their normal operating environments. Powertrain research is also carried out on multiphysics systems that include mechanical, electric, and thermal power systems, such as ship energy systems.
Mechatronic industrial systems include machine dynamics, machinery for bioproduct production and machining and measurement of large machine components. Aalto Industrial Internet Campus and the mechatronics laboratory serve as primary research environments in this area.
Research in product development in the department can be divided into two streams: product development methods and development practices in organisations.
In product development methods, our research focuses on idea generation, conceptual design, modularisation, integrated product development processes and industrial design and design for manufacturing.
In terms of product development practices in organisations, our research investigates how different types of individual perceptions, team practices and organisational processes support developing innovative products.
