My Skills
My Projects
1. Door Model Build
Build the door model by realizing robscans, spotwelds, adhesive, spotline and bolts. Material is assigned, and unmodeled parts are realized as virtual masses. SPCs are applied to hinges and ceilings, with SOL103 used for frequency and mode shape comparison against a reference model.
Tools Used: Nastran, Ansa_22.1.0, Animator4.2.1.3
2. BiW Model Build
Objective is to build the BIW from the start model by realizing spotwelds, robscans, bolts, and bondlines. SOL 103 is performed to check for free parts and predict torsion and bending modes.
Tools Used: Ansa, Nastran, Animator4.2.1.3
3. Mirror Vibration Analysis
Evaluated mirror blurring. ORVM is modeled with tetra elements, SPC applied at mounting locations. Response taken at glass. In integration, SPC applied at ceilings, hinges, and latch. SOL 103 and SOL111 used for calculations, results plotted.
Tools Used: Nastran, Ansa_22.1.0, Hyperview
4. Oil Canning Analysis of Door
Predicted elastic deformation and identified soft or hard oil canning on door surfaces not supported by substructure. Geometry modeled with shell elements, outer edge constrained in all DOFs. Load applied at given coordinate, NLGEOM activated, non-linear material used. Load vs deflection curve generated.
Tools Used: Abaqus, Ansa
5. Sag Set Analysis of Door
Measured maximum displacement and stress at the hinge. Door and reinforcements modeled with shell elements. Load applied at latch point in z-direction and then unloaded. Outer edges of the door are constrained in all DOFs. NLGEOM activated for large deformation effects, non-linear material defined.
Tools Used: Abaqus, Ansa
6. Denting Analysis of Door
Measured permanent deformation after indenting. Door modeled with shell elements, indenter with rigid elements as master surface, outer panel as slave. Load applied to indenter's reference node, then unloaded. Remaining dent depth measured. NLGEOM activated for large deformation, non-linear material assigned.
Tools Used: Abaqus, Ansa
7. Lateral Stiffness Analysis of the Hood
Predicted elastic deformation and verified sufficient bending stiffness of side beam hood. Hinge points constrained in 5 DOF (rotational Y-axis free), support points constrained in load direction. Load applied vertically to inner panel via kinematic coupling. Stiffness calculated by measuring displacement at load location.
Tools Used: Ansa, Abaqus 6.14
8. Torsional Stiffness Analysis of the Hood
Predicted elastic deformation and distortion of the front area of the Hood. Hinge points constrained in 5 DOF (rotational Y-axis free), right support point constrained in load direction. 100 N vertical load applied on front left support point to distort the structure. Stiffness calculated by measuring displacement at load location.
Tools Used: Ansa, Abaqus 6.14
9. C27 D10 Rear support BJ Analysis
Objective: choose optimum rear mount design. 3/8-inch thread bolts modeled using C3D8I elements. Different rear mount designs modeled with tetra elements. NLGEOM activated for material and geometric nonlinearity. Analysis in three steps: pretension load, bolt compression, real G-loads. Fatigue factor and factor of safety calculated.
Tools Used: Abaqus, Hypermesh 17.0, Simlab
10. Underground Mining loader FR Analysis
Main objective: find structural integrity of Underground Mining loader components (tensioner pulley, shaft, tensioner, fan arm bracket) under real G-loads in three directions simultaneously for frequency sweep of 1 to 500Hz. FE model generated from CAD. Iso mounts modeled with SPRING2 elements. Fatigue factor calculated.
Tools Used: Abaqus, Hypermesh 13.0, Simlab
