Using BIM and VR, the deep excavation construction noise and vibration simulator is divided into control devices, material plate, impact simulator and VR equipment. Korea Institute of Civil ...

This is a 3D model of a four-cylinder engine in MapleSim software from Maplesoft. The software lets designers use symbolic and numeric techniques to diagnose vibration issues on machines powered by ...

In-vehicle subjective evaluations of a mid-sized SUV exhibited an objectionable vibration character when driven over smooth road surfaces with minor rolling irregularities. As a result, a project was ...

Components in measuring equipment and devices, components of general mechanical engineering or structures in aerospace are often exposed to strong dynamic loads during their use. In order to avoid ...

Highly Accelerated Lifecycle Testing (HALT) is the gold standard for physical testing of a product to determine reliability issues. Deriving the physical constraints and fatigue issues for a design ...

Today’s powertrain designs, like start-stop systems or downsized engines, often induce torsional-vibration phenomena, which negatively impact NVH (noise, vibration, harshness) performance and ...

Many readers probably think “black magic” describes the math involved in finding the dynamic response of a structure from random excitation. When can you be sure you have jumped through all the ...
