What is the meaning of the zero stiffness at the nominal position? Could you explain briefly in terms of the engineering perspective.
Project Description:
This project will deal with vibration isolation systems widely used in lorries, buses, large off-road heavy surface mining, construction, and agricultural vehicles. The use of a vibration isolation system is a common way to protect the vehicle operator from the adverse effects of vibration exposure. The conventional suspension systems include an air or metal spring and hydraulic absorber. Due to the physical restrictions of such systems, there is a need for a more reliable and efficient way of vibration isolation. The objective of this project is to investigate a dynamic suspension system that minimizes the vertical oscillations of the vehicle's body regardless of road conditions. This can be achieved using systems with near-zero stiffness at the nominal position, which include an air-spring and pneumatic damper. The scope of the project includes mathematical modeling of the mechanical and pneumatic system. The student should have some basic knowledge in applied mechanics as well as strong computational skills.
