Simulation Services

At NESTech, CAE forms the cornerstone of our digital engineering capabilities, with 25+ years of experience empowering mechanical engineering industries worldwide. We replace traditional trial-and-error approaches with comprehensive simulation solutions that optimize product performance, reduce development time by up to 40%, and minimize physical prototyping costs. Our end-to-end virtual product development services - from structural and thermal analysis to CFD simulations and final validation - enable clients to bring safer, more efficient products to market faster.

Why CAE Matters

Accelerates product development by reducing dependence on costly and time-consuming physical prototypes.

Enhances design accuracy through predictive simulation of structural, thermal, vibrational, and fatigue behavior.

Reduces failure risk by identifying potential issues before they manifest in real-world conditions.

Improves product quality and compliance with global engineering standards.

Structural Analysis (FEA)

Our structural FEA services ensure that your components and assemblies can withstand operational and extreme conditions. We simulate various load scenarios to evaluate stresses, deformations, and safety factors.

Applications:

  • Component integrity validation
  • Structural failure prediction
  • Lightweighting and material optimization

Benefits:

  • Reduced weight without compromising strength
  • Better understanding of design limits
  • Compliance with industry safety norms

Thermal Analysis

Thermal Analysis involves the study of heat transfer within and between materials and systems due to conduction, convection, and radiation. NESTech uses thermal simulations to predict temperature distribution, thermal stresses, and deformation in components under various loading and environmental conditions. This analysis is critical for ensuring materials and components can withstand thermal loads during operation without failure or performance degradation.

Modal and Vibration Analysis

Modal and Vibration Analysis focuses on evaluating the dynamic behavior of structures under vibrational loads. Modal analysis identifies a structure's natural frequencies, mode shapes, and damping characteristics. Vibration analysis extends this to understand how a component responds to harmonic, random, or transient vibrations. At NESTech, we use advanced simulation tools to analyze vibrations at both component and system levels, ensuring designs are free from resonance-related failures and perform reliably in dynamic environments.

Applications:
Our Modal and Vibration Analysis services are widely applied in:

  • Aerospace: Aircraft fuselage and wing structure resonance checks, engine component vibration damping
  • Industrial Machinery: Rotary equipment, compressors, gearboxes, and pumps subjected to cyclical or rotational forces
  • Consumer Products: Appliances and electronics where user comfort and product longevity are affected by vibrations
  • Rail and Infrastructure: Rail coach vibration modes, comfort index evaluation, and component fatigue under cyclic loading

Benefits of Modal and Vibration Analysis with NESTech:

  • Identification of critical resonance frequencies to avoid failure
  • Improved design stability under dynamic conditions
  • Reduction in noise, vibration, and harshness (NVH) for better user experience
  • Enhanced fatigue life by minimizing vibrational stress
  • Better component reliability and safety in service environments
  • Optimized product performance with reduced maintenance costs

Kinematic and Mechanism Analysis

Kinematic and Mechanism Analysis involves studying the motion of mechanical systems without considering the forces that cause them. It focuses on the relative movement between components-such as velocity, acceleration, displacement, and angular motion-ensuring that a mechanism functions smoothly and efficiently within its operational limits. At NESTech, we use multi-body dynamics tools to model and analyze mechanisms from simple linkages to complex assemblies like suspension systems and robotic arms. This analysis is essential in the early design phase to validate movement paths, identify interferences, and optimize geometry.

Applications:
Our Kinematics and Mechanism Analysis services support clients in a variety of industries:

  • Automotive: Steering systems, suspensions, clutches, gear shifts, convertible roof mechanisms
  • Aerospace: Landing gear deployment, control surface linkages, cargo door mechanisms
  • Agricultural & Construction Equipment: Lifting arms, rotary tillers, linkage systems, loader buckets

  • Accurate simulation of motion paths to verify design functionality
  • Prevention of collisions and interferences between moving parts
  • Optimization of motion parameters for smooth and efficient operation
  • Reduction in physical testing cycles through virtual validation
  • Improved performance and product usability through refined mechanism design
  • Better ergonomics and user interaction analysis for systems with human interfaces

Fatigue and Durability Analysis

Fatigue and Durability Analysis is critical for evaluating how components and structures perform over time under repeated loading conditions. Unlike static analysis, fatigue focuses on the cumulative damage caused by cyclic stresses, which can lead to crack initiation and eventual failure-even when the stress levels are below material yield strength. At NESTech, we use industry-standard tools and methodologies to predict fatigue life, identify high-risk areas, and suggest design modifications to enhance product longevity. Our analysis supports both high-cycle and low-cycle fatigue scenarios, incorporating variable loading conditions, environmental factors, and material behavior.

Applications:
NESTech offers fatigue and durability analysis across multiple sectors, including:

  • Automotive: Chassis, suspension systems, crankshafts, connecting rods, engine mounts
