DVP, Performance, Strength, Durability and Endurance Test for different automotive systems


Different Types of DVP Tests 

Child Part Simulation Test
Check/Test
Feedback
Child Part Assembly to make whole vehicle in Digital Mock Up
Fouling, Touching, Tolerance, Ergonomics, Dimension
Change Layout, Dimension, Location 
Child Part Durability Simulation
Stress, Strain, Natural Frequency, Bending Moment, Braking Force, Leakage Pressure  
Change Stiffness, Thickness, Weight, Material , Manufacturing Process, Increase Factor of Safety
Child Part Dynamic Simulation
Fatigue, Cyclic Loading, Wear,
Pressure & Temperature Variation, Creep 
Child Part Performance Simulation
Coefficient Of Discharge & Pressure Drop for all fluid flow parts=
Throttle, Intake/Exhaust Manifold etc.
Electricity Consumption for all sensor and actuators.
