Modification of Disc Brakes Using Rotating Brake PadsIOSR Journals
Under the topic ‘Modification of Disc Brakes using Rotating Friction Pads’, I have studied different
components of disc brake which includes rotor, calipers, and fixed friction pads.My main aim is to increase the
braking effect by modifying the existing design by using rotating friction pad. This friction pad is made to rotate
in opposite direction as that of rotor, this is done by using a separate assembly of compound gear train. In this
assembly 2 shafts are used, one shaft is connected between tire and gear and second shaft connects gear and
rotating friction pad. Both the gears are meshed with each other. As the wheel rotates in clockwise direction,
the gear attached to it will also rotate. Other gear which is in meshed position with first gear will rotate in anticlockwise
direction. This will help to move friction pad in anti-clockwise direction as that of wheel’s clockwise
motion. Aim for using rotating friction pad is to provide maximum possible friction which results in retardation
of motion, rotating friction pad not only will provide the friction due to contact but will also provide the friction
due to rotation. Calculations regarding speed of gears, and motion of wheel will clearly elaborate the idea, this
slight modification helps in reducing braking time. Important thing in this innovation is that the energy required
to stop the wheel or disc of brakes is transmitted from wheel only

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas.

3. INTRODUCTION
Differential is an essential part of any four wheeled vehicle.
A differential allows wheels of a vehicle to rotate at different speeds.
This is necessary when the vehicle turns.
4. OBJECTIVE
PHASE 1
To study the differential and working in a vehicle.
To study gear terminology.
PHASE 2
Design of whole differential system.
Design of different parts on sheet and CAD software with the help of
ANSYS software.
Assembly of differential in CAD software.
Fabrication.
5. PARTS OF DIFFERENTIAL SYSTEM
Pinion drive gear :- Transfer
power from the drive shaft to the
ring gear.
Ring gear :- Will transfer power to
differential case assembly.
Spider gear :- Gear lies at the
heart of differential and special
mention should be made about its
rotation.
Differential case assembly:- Hold
the gear and drive the axel.
Rear drive axel:- Transfer torque
from differential assembly to drive
wheels.
6. WORKING OF DIFFERENTIAL
While taking turn, the inner and outer wheels have different turning radius.
The inner wheel travel less distance.
From the drive shaft power is transferred to pinion gear first, since pinion
and ring gear are meshed , power flow to the ring gear.
As the spider gear is connected with the ring gear, power flows to it.
At last power from spider gear gets transferred to both side gears.
7. DIFFERENT CASES
THE VEHICLE MOVES STRAIGHT
In the case the spider gear rotates along with the ring gear but does not
rotate on its own axis.
So the spider gear will push and make the side gears turn and both will
turn at the same speed.
8. VEHICLE TAKES A TURN RIGHT
In this along with the rotation of the ring gear its rotates on its own axis.
So the spider gear having a combined rotation.
When the spider gear is spinning as well as rotating peripheral velocity at
the left side of spider gear is the sum of the spinning and the rotational
velocity
But the right side it is the difference of the two since the spin velocity is in
the opposite direction at this side.
9. OTHER FUNCTION OF DIFFERENTIAL
First is the speed reduction at the pinion ring gear assembly. Since the
power flow at the pinion and ring are the same such a speed reduction will
result in a high torque multiplication.
Can also note one speciality of the ring gear, they are hypoid gear have
more contact area compared to the other gear pairs.
The other function of the differential is to turn the power flow direction by
90 degree.
10. DRAWBACK OF STANDARD DIFFERENTIAL
It is not working in the situation where one of the rear wheel having a good
traction and other having a slippery surface.
11. DESIGN PARAMETERS
1) Input parameters:-
i. Input power
ii. Input speed
iii. Input torque
iv. Max weight of vehicle
v. Distribution of weight at front and rear axle
vi. Gear ratio
12. FORCE ACTING TO ROTATE SPIDER GEAR
The centrifugal and centripetal force are required to turn the spider gear in
anti clockwise while taking right turn and vice-versa
13. WHAT HAPPEN IN THE DIFFERENTIAL IN
DIFFERENT TURNING RADIUS ?
At different turning radius, the speed of outer wheel will vary as compare to
inner wheel.
For Example:-
turning radius of inner wheel = 5 meters
turning radius of outer wheel = 6 meters
1) The distance travel by inner wheel is circumference of inner circle = 2*pi*r => 2*3.14*5=>
31.41 meters
2) The distance travel by outer wheel is circumference of outer circle=2*pi*R=>2*3.141*6=>
37.692 meters
3) Therefore,
the relation between two wheels speed = 37.692/31.41=> 1.2
So , we can say that outer wheel is 1.2 times faster than inner wheel at this turning radius.
