Objectives of the Course
Natural Intelligence is needed to understand the Artificial Intelligence and Machine Learning (AIML) capabilities and limitations.
Growing awareness of NVH (Noise, Vibration and Harshness) has necessitated the valid design of aircrafts, machines, automobiles, buildings, industrial facilities and home appliances.
With the increasing number of standard regulations and human ride comfort associated with NVH makes it mandatory to control vibration and noise leading to quieter technology in pumps, engines, compressors, chillers and other consumer products consumer for OEM companies to stress upon the products without NVH problems.
AI & ML achieves structural condition health monitoring of machinery in industries. Analytical, MATLAB and FEM based tools such as ANSYS, COMSOL, NASTRON, ABACUS, SYSNOISE and Modal Analysis software tools such as LMS, Mescope helps to achieve these goals.
This course is for engineers/ scientists/ entrepreneurs /instructors in the industries/ institutes/ universities to learn the analytical and experimental skills to tackle the problems related noise, vibration and harshness (NVH) during design and manufacturing stage for technically superior and commercially viable product to achieve “EMPOWER INDIA WITH SKILL AND Knowledge” for “AATMANIRBHARA BHARAT ABHIYAN”.
