VERTICAL VIBRATIONS OF BASE ISOLATED MACHINEFOUNDATIONS
Vibration of base isolated machine foundations has been studied using the Scaled Boundary Finite Element Method (SBFEM) and the cone model method. The dynamic stiffness of soil supporting rigid massless foundation was determined.

Dynamic stiffness identification methods: experimental study and validation
In a vehicle, the operation of mechanical systems generates undesirable vibrations and noise, and their reduction requires the study of three parts: vibrating systems, receiving structures, and connecting interfaces. The study presented in this paper concerns the connecting interfaces between subsystems.

Joint Stiffness Identification of a Heavy Kuka Robot with a Low-cost Clamped End-effector Procedure
This paper proposes two new methods for the identification of static stiffnesses of multi degrees of freedom heavy industrial robots. They are based on a locked link joint procedure obtained with an end-effector fixed to the environment. The first method
