Fillets, chamfers.
Surface , volumes.
Holes and other details Etc.
ADVANTAGES: LIMITATIONS:
 Saving time and money by
reducing the number of
prototypes required.
 Accepts new design concept .
 Improvements and
modifications
 Commercial software packages
and the required hardware.
 High investment cost
 Gives solutions or results, not
remedies.
 Analyst must be proficient
Stress analysis of chassis ppt
MATERIAL OF THE CHASSIS IS AS PER IS: - 9345
STANDARD IS STRUCTURAL STEEL WITH ST37
Material Property Value
Ultimate Tensile Strength 370 to 490 N/mm2
Modulus of elasticity 2.10 x 105 N / mm2
Poisson Ratio 0.29
Radius of Gyration R
114.30 m
Meshing is the process of breaking up the model into
smaller pieces that can be solved by the software using advanced
matrix math and then merged together to show the correct result
for the whole.
 BC
• FIX SUPPORT
• CYLINDRIVCAL
SUPPORT
• TEMP ETC.
 LOADS
• FORCE
• PRESSURE
• CONVECTIONS ETC.
