FEA Projects
SimFirst, an engineering consulting firm, was founded in 2018 to provide quality solutions in the Engineering and CAE fields.
Nuclear Applications
Seismic analysis requested to check the conformance of valve as per ASME BPVC-III Rules for the construction of Nuclear Facilities components Division 1 – Subsection NC Class 2 Components.
ChallengesSeismic analysis, drafting standard format report
ConclusionsThe spring loaded safety valve DS112 qualifies seismic evaluation requirement as per ASME BPVC III, Division 1-NC
To check and optimize the strength of major parts of Hydraulic Test Bench for tension, compression & buckling condition.
ChallengesIdentifying Loading & Boundary conditions for assembly in neutral position.
Conclusions- For tension & compression loading, the equivalent von-Mises stress for all parts are below yield strength.
- For buckling condition, design load factor from ANSYS (Load Multiplier) is 12.
Defense Applications
To find out the strength and integrity of pressure regulator valve assembly for shock in all three directions X, Y & Z.
ChallengesShock analysis
ConclusionsShock Analysis of valve in Longitudinal X, Horizontal Y and Vertical Z direction
- All parts have stresses below yield strength.
To find out the strength and integrity of pressure regulator valve assembly for Random Vibration in all three directions X, Y & Z.
ChallengesRandom vibration profile
Conclusions- Since total damage in valve for all three directions X, Y & Z for 2 hours is less than 1. Hence the valve assembly is safe for random vibration.
- Random Vibration – X, Y & Z Direction All parts have equivalent stress (3 sigma) less than yield strength.
Oil & Gas Applications
Optimization of Electrical Actuator Worm Gear Housing Assembly for applied torque.
ChallengesSolving actual loading condition & splitting forces on various parts.
ConclusionsShock Analysis of valve in Longitudinal X, Horizontal Y and Vertical Z direction
- The total deformation of housing and cover is slightly increased but it is within acceptable range.
- The total weight reduction in existing assembly is 5.88 kg based on stress limits in housing & cover.

Automotive
To optimize the snap fit of car roof rail for force requirement of snapping & unsnapping 6.5 kg (max) & 11 kg (min) respectively.
ChallengesShock analysis
Conclusions- The force required for snapping & unsnapping will be approximately 8.2 kg & 12.9 kg.
- For snapping & unsnapping, the equivalent strain in all the components are below break limit.
| Location | Total Deformation (mm) | Snapping Force (kg) | Unsnapping Force (kg) |
|---|---|---|---|
| 4 | 1.62 | 8.2 | 12.9 |
