EXECUTIVE SUMMARY
◼ This report summarizes a detailed engineering analysis conducted using SOLIDWORKS SIMULATION,
a Finite Element (F.E.) analysis software. The analysis focused on the Static Elastic stress analysis of the
Structural Validation, aiming to assess the part's performance characteristics under static loads. Threedimensional (3-D) and Two-dimensional (2-D) models were created, and the analysis provided insights into
stress and deflection. The report includes methodology, references, conclusions, and recommendations for
design modifications to improve the part's performance. The analysis findings serve as a foundation for
enhancing the part's structural integrity under static loading conditions.

INTRODUCTION
◼
Detailed three-dimensional (3-D) solid and Two-dimensional (2-D) Shell, Finite Element (F.E.) computer
models were constructed for Static Elastic stress analysis of the Seismic Validation.
◼
The analysis was performed to determine the structural integrity and performance characteristics of the
Static Load Condition Validation under the specified design.
◼
This report documents in detail the technical approach, FE computer modelling, maximum stress at
critical locations and maximum static stresses in the component.
◼
Tetrahedron elements are three-dimensional (3D) solid elements that are shaped like pyramids with four
triangular faces. Tetrahedral elements are commonly used in finite element analysis (FEA) to mesh
complex geometries, They have four nodes (for first-order elements) or ten nodes (for second-order
elements).
◼
Triangular elements are 2D finite elements commonly used in finite element analysis (FEA) for meshing
surfaces, especially in complex geometries. They come in different types, such as linear (3-node) and
quadratic (6-node) elements, with higher-order variations for improved accuracy. While triangular
elements are easier to use for irregular shapes and adaptive meshing, they generally require more elements
to achieve the same accuracy as quadrilateral elements. They are widely applied in plane stress/strain
problems, shell and plate structures, and fluid-structure interactions.

SYSTEM DESCRIPTION
Figure 01 : Main loading frame of CYLINDER LIFTER
2.1 System Explanation
◼
CYLINDER LIFTER
The segment was modeled for the analysis and run to check whether the lifting assembly can lift a cylinder
of an average weight of 400 kg. the static step is run against the load of gravity and cylinder weight of
400 kg to identify the overall behavior of the assembly without having to analyze the entire assembly,
which could be time-consuming or impractical.

ISO Clipping :
The Below plot shows that stress concentration in body is due to geometric and FEA limitations,
the above plot contains the geometries that had stress of more than 140 MPA.
Note: The gray coloured geometries are rigid bodies it is not the part of plot Legend.

VON MISES PROBE RESULTS AT DIFFERENT LOCATIONS
The above Fig. shows the stress distribution under 400 kg & self-weight. The selected nodes are taken
into account based on provided Interactions, Loads & Fixtures. The stress is concentrated above & in
between of Frame & Piston cylinder arrangement and it needs to be addressed.
Stress Trend (node: 18649):
Highly concentrated area or components need to redesign.

CONCLUSION AND RECOMMENDATION
◼
The Static elastic analysis provided insights on the “Cylinder lifter assembly”, under the provided load
and condition (DEAD WEIGHT + SELF-WEIGHT) at the maximum stroke length of 300 mm, with the
assumption made of having rigid bodies such as a hydraulic cylinder in the simulation:
◼
As the initial provided CAD was unable to withstand high loading. Due to these overall changes in the
frame structure and bucket were needed to address this condition the necessary modifications were made
to the CAD assembly with the required approvals. The ladder pattern structure has been selected for
further simulation.
◼
From the FEA results calculated maximum displacement is 2 cm at the bucket, overall Elastic strain is
1.365e-3, maximum Von Mises stress is 250 & 98.18 percent Von Mises stress under the allowable stress.
◼
The hydraulic cylinder to frame linkage part is subjected to high stress above the allowable stress and the
same location the failure in the bolt connection is found, thus needs to be perform the necessary Design
modification.
◼
The rest of the parts in the Cylinder lifter assembly are well under allowable stress according to the ASME
BPVC 2021 Section II D for General structural steel (not pressure-rated).
◼
The recommended design changes are as stated below:
 The Bucket can be designed as the Skeleton structure to minimize the displacement further .
 The I or Rectangular beam can be utilised in the high-stress concentration area which is the
hydraulic cylinder to frame linkage part.
 The double shear sheets can be utilized for the bolt connectors.
 The weld can be used at the piston linkage part rather than bolt may increase the structural integrity
 To discuss the above made Recommendations can reach out to us .
