About KTH Vehicle Dynamics
A ground vehicle contains many components that interact with each other, resulting in a complex dynamic system. The division’s goal is to improve the knowledge about dynamic behaviour and function of vehicles (buses, cars, trucks etc.) to lead the development of new vehicles to be more reliable under different driving conditions. The research and education is focused on problems related to handling, rollover and comfort of road vehicles, as well as driver/vehicle interaction, non-linear phenomena and catenary-pantograph dynamics. To solve these problems, aspects on active safety as well as methods for simulation and measurement of dynamic behaviour for efficient product development are considered.
The division is, together with the Division of Railway Technology, responsible for the competence program in Ground Vehicle Engineering within the Master of Science Programmes in Vehicle Engineering and Mechanical Engineering at the Royal Institute of Technology.
Vehicle Engineering Laboratory
Most of our educational activities are conducted in the Vehicle Engineering Laboratory where we have an area for our test vehicles and equipments, one area for lectures and seminars and one area with computers. The laboratory is shared between the Railway, Vehicle dynamics and Aerodynamics group. The students have a kitchen with fridge to store and prepare lunch since when the facilities are not booked this laboratory is open for the students in the Vehicle Engineering programme.
The laboratory have a car lift so that it is easy to work with the test vehicle and store two vehicles simultainiously. The laboratory also have increased seiling so that it can be used to hoist up a car and measure moments of inertia.
In our facilities we also have a stationary driving simulator that have the same software as in VTI moving base driving simulators (MBDS). This enable us to do pre-tests and plan experiments before booking and conducting experiments in MBDS.
Both for education and research activities we have access to a number of test vehicles. First we have the Research Concept Vehicle that is built and managed by ITRL - Integrated Transport Research Lab. This is an over-actuated electric vehicle with four in-wheel motors, four steering actuators, four camber actuators making and steer-by-wire system making is a versatile platform to test, demonstrate and validate different control strategies and evaluate vehicle dynamics effects.
The second vehicle we have is the Volvo S90 R-Design that have access to several CAN signals as well as wired to easy access controllers for e.g. controlling steering, throttle and braking. This vehicle is mostly used in our courses for student to perform various experiments on, cost down test, acceleration and braking tests as well as slalom maneouvres in order to validate simulation models that should represent this vehicle.
The third vehicle which we use for research projects is Hjulius. It is a scaled down remote controlled wheel loader to evaluate different suspension concepts and study the vehicle dynamics stability.
For the experimental work and student activities we have a VBOX 3i Dual Antenna system with an IMU to measure the vehicle states accurately. The system is easy to mount on a vehicle and is easy to move between different vehicles.
