206. "DYN1#1 - A model-based approach for the NVH performance improvement of Soft Close Actuators for automotive applications"

Natali Caterina

The aim of this paper is to describe a numerical vibro-acoustic methodology, experimentally assessed, for the estimation of the overall vibratory and acoustic level of a Soft Close Actuator (SCA), for automotive applications. The process is carried out in order to develop a digital twin enable to represent the Noise, Vibration and Harshness (NVH) behaviour of the real mechanism. The...

207. "DYN1#2 - Optimization of the Energy Input and Output Parameters for Pyroshock Testing"

Viale Luca

During the different phases of a mission, spacecraft equipment is subject to high-frequency shocks, commonly known as pyroshock since they are caused by explosive materials. The requirements for space qualification are usually expressed in terms of Shock Response Spectrum (SRS) acceleration €“ indicating the damage that a shock could potentially cause to a structure €“ and depend on the...

208. "DYN1#3 - Numerical analysis of the dynamic behavior of rotor shafts in permanent magnet synchronous machines"

Poupon Thomas

In order to design permanent magnets synchronous machines as quiet as possible, we propose a predictive magneto-mechanical vibration model. This model allows for describing the dynamics of the system under operating conditions by including a strong magneto-mechanical coupling between the electromagnetic forces and the dynamics of the motor shaft. The Maxwell pressures are calculated...

209. "DYN1#4 - Control of an acoustic mode by a digitally created Nonlinear Electroacoustic Absorber at low excitation levels: Analytical and Experimental results"

Morell Maxime

Noise reduction becomes important to raise acoustical comfort and to prevent the population from additional disorders. Acoustic passive devices such as acoustic foams and passive resonators have their limitations. Active Noise Control has a high energy consumption and works well only in local zones. The concept of Impedance Control is very efficient around its resonant frequency. The Impedance...

210. "DYN1#5 - Exploring the Impact of Defect Geometry on Bearing Dynamic Behavior Using Spall and Indentation Models"

Schwarcz Ori

11/07/2023 15:20

Dynamic modeling of a bearing is an effective tool that is used to research the bearing behavior under various conditions. Models yield clean results that include data that cannot be obtained through direct experimentation, such as internal forces and the positions of rolling elements. By simulating a faulty bearing, it is possible to thoroughly examine the effect of the defect's shape on the...

211. "DYN1#6 - Unknown load torque estimation on rotary drivetrains with exploitation of angular periodicity in an extended Kalman filter"

Van Der Veken Thijs

11/07/2023 15:40

Accurate knowledge of the torsional vibrations is key for condition monitoring, control and design optimization of mechatronic drivetrains. An often applied solution is to combine the knowledge of the system dynamics in the form of a physics-based model with an informative but limited set of measurements in a stochastic estimation algorithm. A critical difficulty in this estimation arises from...
