Spring is an elastic body whose function is to distort when loaded and to recover its original shape when the load is removed.
APPLICATION OF SPRINGS
To apply forces as in brakes, clutches and spring loaded valves.
To store energy as in watches, toys.
To measure forces as in spring balance and engine indicators.
To cushion, absorb or control energy due to either shock or vibration as in car.The material of the spring should have
high fatigue strength,
high ductility,
high resilience and
creep resistant.
It largely depends upon the size and service.
The strength of the wires varies with size, smaller size wires have greater strength and less ductility, due to the greater degree of cold working.
Severe service means rapid continuous loading where the ratio of minimum to maximum load (or stress) is one-half or less, as in automotive valve springs.
Average service includes the same stress range as in severe service but with only intermittent operation, as in engine governor springs and automobile suspension springs.
Light service includes springs subjected to loads that are static or very infrequently varied, as in safety valve springs.
The springs are mostly made from oil-tempered carbon steel wires containing 0.60 to 0.70 per cent carbon and 0.60 to 1.0 per cent manganese.

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.

2. Introduction
Hydraulic lift is a material handling device
Hydraulic lift is a type of machine that uses a
hydraulic cylinder to lift and lower objects by
applying relatively small force compared to the
weight of the object to be lifted.
It’s working is based on Pascal’s Law.
3. Design Procedure
Design a hydraulic cylinder assembly to lift a load of
500 kg
Scissor Type Mechanism
Bending, Crushing, Shearing and Buckling
4. Material Selection
Scissors Arms: Stainless steel.
Subjected to buckling load and bending load tending
to break or cause bending of the components.
Hydraulic Cylinder: Mild steel
Subjected to direct compressive force, bending
stress, internal compressive pressure.
Top Platform: Mild steel and the base is wood
Subjected to the weight.
Base Platform: Mild steel
Subjected to the weight of the top plat form and the
scissors arms.
6. Design Theory of Calculation
In this section all design concepts developed
are discussed and based on evaluation criteria
and process developed, and a final here
modified to further enhance the functionality of
the design. Considerations made during the
design and fabrication of a single acting
cylinder is as follows:
a. Functionality of the design
b. Manufacturability
c. Economic availability. i.e. General cost of
material and fabrication techniques employed
7. Total load calculation
The hydraulic cylinder is mounted in horizontal
position. The total load acting on the cylinder consists
of:
Mass to be put on lift : 500 kg ;Taking FOS = 1.5 for
= 750 kg rounding the mass to 800kg
Mass of top frame= 22.5 kg
Mass of each link = 40kg
Mass of links of cylinder mounting=4kg
Mass of cylinder=8.150kg
Total Mass = 874.65 kg
Total load = 8580.316N
8. Scissors lift calculations
For a scissor lift Force required to lift the load is
dependent on, Angle of link with horizontal
Mounting of cylinder on the links Length of link.
Formula used
S= a2 + L2 -2aL*cos α
Where ,
S = Distance between end points of cylinder
L= length of link = 0.6 m
α = angle of cylinder with horizontal.
9. Load Calculation of Link
For the link design it has been considered that, the
entire load is acting on half of the link length.
Length of the entire link (L) = 720mm.
Length of the link considered as the beam for the
calculation purpose = 360mm.
The load pattern on the top platform is considered to
be U.D.L. Hence, the load pattern on the link is
uniformly varying load (U.V.L.) due to its inclination
with horizontal.
The calculation is done for the link in shut height
position, i.e. when the angle made by the links with
horizontal is 20˚ .
10. The length of the pin from the intermediate pin to the
bottom roller is considered as a beam. The forces acting
on the beam are-
The reaction offered by the base to the roller, RA resolved
into 2 components.
The reactions offered by the intermediate pin, HB, VB.
The force due to (Payload + Platform weight) resolved
into two components, along the length of the link and
perpendicular to the length of the link.
11. W = force per unit length of the beam can be
evaluated as follows, As the load pattern of U.V.L. is
a triangle, we can say,
W (total force perpendicular to the link) =
(1/2)*base*w
Hyi=8580.316N ;
Hyi/4= (8580.316/4) = 2145.079N
2145.079 cos(20) = 2015.714N
2145.079 sin (20) = 733.66N
Now, 2015.714=(1/2)*360*W
W=11.918N/mm
12. DESIGN OF LINK WITH BUCKLING
As indicated before ,buckling of link with one
end fixed and other hinged :-
b=4h
E=2*105 N/m2 l=0.72m
So we get :
b=1.2m h=30mm
As
:
(Stainless
steel)
13. Checking in bending
Taking moment about point A,
VB * 360 – [(2015.714X*360 *(2/3))]
Therefore, VB = 1343.089N
Therefore RA = 715.026N
So, RA cos (20◦) = 671.904 N
RA sin (20◦) = 244.55N
= 62.5 Mpa,
Thus it is safe for bending.
14. Design of Pin
= 0.5*505/FOS
= 126.25 Mpa
126.25 = 4*F/3.14*D2 *2 = 13.15mm
D = 14 mm____________Selecting standard
value
Sut = 505 Mpa
(Mild Steel)
15. Design of intermediate Link
Force acting on intermediate link :-
Thus =11512.48N
Now by taking moment at one end and
considering length=1m,thus
M= 11512.48Nmm
Again = 62.5Mpa
Therefore d=12cm
16. Design Of Hydraulic Cylinder
F = 8580.316N (Previous Calculation)
One end fixed and other free :-
L=720mm
Le=2L
Buckling
Formula
Diameter of Cylinder:
d=17.4mm → D=2d=34.8mm
E = 250 GPa
(Mild
steel)
17. Area on Cylinder side will be =
951.14mm2
Area on rod side will be= 237.78mm2
Now considering bigger area
Thus P= 12 N/mm2 = 120 bar
18. Designing of Cylinder
Taking Sut= 440 Mpa
Considering Factor of Safety =3, thus
σ = 146.66 Mpa
Now
t= 1.42 mm (for cylindrical part)
(Mild
steel)
