Navin Niraj

I have worked as an Application Engineer with Focus on Finite Element Analysis,

My Main responsibilities:

Provide technical support to customers who uses Ansys Mechanical software of Cadfem India.

Participated in Technical Conferences to showcase the latest development related to FEM.

Trained Client Engineer in Ansys Mechanical – specific software usage.

Technically Guided the Client Engineer in Completing the Simulations Related projects.

Have supported Ansys Customer by delivering POC for their applications.

My main area of expertise is Static, Linear Dynamic (Vibration analysis- Modal, Harmonic, Random Vib.), Transient Analysis, Fatigue analysis, Thermal analysis, Multi body dynamics and Non-Linear Analysis

Projects:

Stress and Fatigue Analysis by Modeling the Sliding and Rolling contact for the engaging gears of a Differential Mechanisms.

Composite Reflector Stress and Modal analysis using Ansys Composite pre and Post.

Structural Integrity of the Ev Battery Pack (Bolt Pretensions, Shock and Random Vibrations, Drop analysis).

Seismic (Wind load) Analysis on the solar wind Farm for a multi-layer Solar Panel.

Multi body Dynamic analysis for the new Break Mechanisms for a two-wheeler scooter (equal distributions of the pressure on the breaks of the front and Back wheel of the scooter)

Leakage analysis of an O-ring/gasket for an electronics components using fluid pressure penetrations.

Non-Linear snap fit analysis for Plastic and Hyper elastic components for Electronic and Automotive applications.

Railway Break Analysis to calculate the amount of heat generated using Coupled filed transient Analysis.

Modal, Harmonic and Rotodynamic analysis for rotor applications.

Projects:

Tightness and Stress Investigation of Steam Turbines using FEA software Ansys Workbench

Check the strength and tightness of turbine and exhaust casing

Boundary conditions – Thermal loads, bolt pretensions, symmetry and steam pressure.

Case Study - Normal operation, Hydro test and Exhaust test.

Solutions: Tightness Calculations, deformations, Contact pressure.

• Analyzed problems and worked with teams to develop solutions.
• Sorted and organized files, spreadsheets, and reports.
• Interacted with customers by phone, email, or in-person to provide information.
• Completed research, compiled data, updated spreadsheets, and produced timely reports.
