Linear Static and Fatigue Analysis of Nose Landing
Gear for Trainer Aircraft
Ashwin C. Gowda*, Novid Basha S. Department of Computer Aided Engineering, Visvesvaraya Technological University
Center for Postgraduate Studies, Bangalore-560072, India
Abstract The main objective of this paper is to present prototype of aircraft landing gear using CATIA V5 software to study the behavior of landing gear as per actual working condition
and to perform structural analysis to study the landing gear behavior for cyclic loading
(fatigue loading). Determining the loading modes in the nose landing gear is subjected to static load and cyclic loads which should be taken into account in the evaluation of the
strength and fatigue life. Initially, the components were modeled with CATIA V5 and
imported to MSC Patran. MSC Nastran is used as a solver. From the obtained limit stresses, fatigue analysis was carried out to find fatigue life of the nose landing gear with
different fatigue load spectra.
Keywords: Nose landing gear, linear static, fatigue, MSC Patran, nastran

An Algorithm to Test Feasibility Predicate for
Robotic Assemblies
M. V. A. Raju Bahubalendruni*, B. B. Biswal Department of Industrial Design, National Institute of Technology, Rourkela, Odisha, India
Abstract Selection of a feasible assembly sequence is an essential element to achieve cost effective
manufacturing process. Test for feasibility predicate is a key segment in assembly
sequence planning, which is generally carried by a skilled industrial engineer. The feasibility predicate test is involved in checking possibility of disassembling a component
from the assembled product through a collision free path. To attain economic assembly
process, the feasibility predicate test must also results the optimal disassembly direction. In the current paper a novel method called “modified bounding box method” to obtain
the optimal feasible directions for a component is illustrated with examples. An algorithm to integrate the methodology with 3D CAD environment to automate the process is also
well described.
Keywords: Modified bounding box method, robotic assemblies, feasibility testing

Bending Stress Analysis of Involute Helical Gear and
Wildhaber-Novikov Gear
Veena Kumari N*, P.V Srihari, K Ramachandra
Department of Mechanical Engineering, R V College of Engineering, Bangalore, Karnataka, India
Abstract This paper presents a bending stress analysis for Wildhaber-Novikov circular-arc gear
(W-N gear) and involute helical gear. Bending stress analyses performed are under continuous load transmission during rotation using finite element method. Using CATIA
V5 R19, three dimensional W-N gear and involute helical gear are modeled by
considering same number of teeth, module, helix angle, pressure angle and face width.
Then nonlinear contact analysis was conducted on involute helical gear sector and W-N
gear sector using LS-DYNA. A comparative study was carried out to study the variation of contact stresses in involute helical gear sector and W-N gear sector. In this study, we
can see that the maximum bending stress is two times greater in involute helical gear than that of W-N gear.

Abstract The process of deep drawing plays a vital role in the production process of different parts in various process environments. Even though there is lot of variations in the production
of parts during deep drawing with conventional processes to the latest automations in the
manufacturing. There is a need to develop different die designs by varying input processes parameters for the deep drawing process in an optimum manner. The objective
of the present study is to determine the influencing of die corner radius in deep drawing
process and analyzing the process by varying the die corner radius. As the die corner radius plays a vital role in manufacturing the product in deep drawing process. Lower the
die corner radii the part is subjected to tearing effect and higher the die corner radii, wrinkling is observed. The present work deals with the different die corner radii for
stainless steel blank. Static analysis and transient analysis is carried out in ANSYS for (4,
5, 6, 7, and 8 mm) corner radii of the die.
Keywords: Deep drawing, corner radius, stainless steel, ANSYS

Damping Analysis of Composite Drive Shaft using
Computational methods
Gowda A. C.*, Prasad T. H. P., Kumar S. Department of Computer Aided Engineering, VTU-CPGS, Bengaluru, India
Abstract Drive shaft used in automotive is a critical component which comes under the influence of
different types of loads in operation. Torsional loading is one of the prime causes
contributing to its failure. Most of the research on drive shaft was focused on evaluating natural frequency, torsional strength, buckling torque using analytical approach and also
using FEM. This project work deals with the analysis of damping behavior of E-
glass/epoxy composite drive shaft for an automotive application. Torsional load will be considered for the load amplitude and the analysis will be carried out based on finite
element method. The main aim of the project was to compute the loads on a drive shaft of an automobile by FEA using ANSYS 12 for evaluating natural frequency, torsional
frequency and to predict its damping behavior. Drive shaft was modeled using CATIA,
which was imported as IGES format to ANSYS workbench. The model was meshed in ANSYS workbench using hex dominant method and boundary conditions were applied.
Natural frequency, torsional frequency, and damping behavior were evaluated for different volume fractions of glass fiber–epoxy composite. The obtained results from the
ANSYS workbench were validated with the calculated analytical results.
Keywords: FEA, ANSYS, IGES, FEM, CATIA

Evaluation of J-Integral and Fatigue Crack Growth Rate
of Semi-elliptical Crack in Compressor Blade
Sudershan*, Ashwin C.Gowda, Kirthan L. J. Department of Computer Aided Engineering, VTU-CPGS, Bengaluru, India
Abstract Gas turbine compressor blades are subjected to centrifugal, gas bending and vibratory
loads. This repeated loading and unloading can reduce the life of compressor blades.
This research aims at the estimation of fatigue crack growth rate of various three-
dimensional cracks in a compressor blade considering the J-integral calculations for a
semi-elliptical crack, subjected to centrifugal loading. Static stress analysis was carried
out to ascertain the critical region or crack zone of the blade. The maximum Von-Mises stress was found at the fillet region near the root of the blade, the predicted state of stress
has helped in identifying the region of singularity which may lead to crack initiation. Finite element method was used to evaluate the range of J-integral solutions in the blade
with a semi-elliptical flaw. Semi-elliptical crack lengths ranging from 0.5 to 3 mm were
considered in the crack zone. J-integral was evaluated for rotational velocity of 10,000 rpm. The J-integral range obtained is employed to predict fatigue crack growth
rate by using Paris law. Fracture module in Ansys workbench was used for evaluation of J-integral Mode IІ at the surface interception point varied from 3.6527 to
45.1071 MPa√m. Fatigue crack growth rate at the crack length was determined and it
was found that fatigue crack growth rate at the surface interception point increases with
increase in crack depth. Fatigue crack length growth rate increased from 1.20015E-4 to
4.8460E-3 m/cycle of b = 0.5 to 3 mm for 10,000 rpm. Also the fatigue crack growth rate
estimated may be large, since the effects of crack closure were not considered. The obtained solution is limited by contour integral evaluation for defined crack geometries
and its orientation or crack propagation direction. Stress field at the crack tip is a function of crack geometry and orientation. With the rotational velocity of 10,000 rpm,
the behaviour of fatigue crack length growth rate was estimated. It was concluded that at
the surface crack interception point, fatigue crack growth rate increases with increase in crack depth.
