efficycle, trike, hybrid trike efficyle event by team chanakya

1. INTRODUCTION
• Efficycle is energy efficient hybrid human powered- three
wheeled-electric vehicle. It has tadpole configuration. The
design of it includes the complete CAD models, designs of
subsystem such as brake, calculation and details of parts that
will be used to build the vehicle.
• The frame of the vehicle is designed in creo 2.0 and the
subsequent will be analyse in ANSYS 15.0.
• In this system, the brake analysis will be thermal and structural
which is also done in ansys 15.0.

2. NEED
• To design and manufacture safe & eco-friendly
vehicle.
• To design chassis with ride comfort, controls
and dynamic safety.
• To reduce weight of chassis and improvement
of strength in weak zones and to analyse
efficient braking system.

Analysis of the chassis
of TATA super ace
The effect of static load and give an analysis
of the chassis of TATA super ace using ANSYS
workbench and its verification using solid
mechanics. The chassis of TATA super ace is
of ladder frame type.The chassis has been
modeled in CATIA V5R18 using the most of
the actual dimensions. FEM analysis was
done using ANSYS 14 workbench.

A review on”Finite
Element Analysis”
using Ansys
To give an introduction to this static stress
analysis method using ANSYS APDL 12.0,
covering topics such as impact force
determination, loading points, convergence
of nodes, and the mesh size dependence of
generated stress. The analysis highlights the
areas of high stress concentration, which
need a change in design. This analysis
approves of a reasonable design, which can
form the basis for a detailed Modeled.

Design and Analysis of
Disc Brake for a
Tadpole Hybrid Trike
One most critical system in the vehicle in
context of safety is brake systems other than
other expensive systems .This describe the
design and analysis of a mechanically actuated
disc brake for a hybrid trike in tadpole
configuration. In context of design of brakes the
analysis is done replicating practical physical
boundary conditions.

FE Modeling and
Analysis of a Human
powered/Electric
Tricycle chassis
The paper describes the study carried out on a
Tricycle vehicle required to be designed for SAE
NIS EFFICYCLE virtual design event. It describes
the role of virtual simulation tools in design
stage of the Tricycle vehicle. The CAD model of
the Tricycle was created using Pro-E software.
The chassis structure was imported in ALTAIR
HYPERMESH where the Finite Element model
was prepared incorporating different boundary
conditions (loads/constraints). The model
consists of CONM elements for representing
concentrated masses (drivers and payload)
which are connected using 1-D elements.

5. Aim:- To design chassis and its analysis by using
CAD/CAE software. Also the analysis of brake system.
Objectives:-
• Design the tricycle in order to check its safety and
stability.
• Increase the efficiency with reducing unwanted parts
of frame .
• To develop and evaluate a most suitable frame and
braking system.
• Low budget high efficient vehicle established.

6. D. Analysis
The analysis of the design was carried out by FEM analysis software ANSYS 15.0 in order to ensure that the
designed vehicle is safe.
C. Design
Here we actually designed the vehicle in modeling software CREO WILDFIRE 4.
B. Ergonomics
After assuming the dimensions our main area of interest was to make the vehicle ergonomic for an average
adult person.
A. Assumptions
Here basically considering the constrains of dimensions we first of all assumed the dimensions of the vehicle.
METHODOLOGY

7. G. Aesthetics
In order to make the vehicle more attractive and convincing its aesthetic considerations like
F. Manufacturing
During manufacturing various parameters like serviceability, craftsmanship and cost reduction
were considered.
E. Analysis
Again the analysis was done of the modified design and it will have to be safe.
E. Modification in design
Based on the results obtained from analysis modifications were done in the existing design.
