SimMultibody systems
SimMultibody
offers the multibody simulations for the environment of 3D mechanical systems
like the vehicle, robots, suspensions, and assembling of pistons in this research.
By using the block which is also presented the constraints, bodies, sensors.
SimMultibody helps to develop the control system as well as test the level of
system performances. Then also parameterize the model by using MATALB variables
as well as the design of control system.
Model 1: Assembly of
piston of Kinetic analysis
The given requirements is the assembly
of piston, where the motorcycle racing team is sued the APrilila 250V-Twin and
approached to elaborate the assembly of pistons, by the step files. The
cylinder is running with Nickel and mild steel that is also confirm by testing and
give the coefficient of friction is 0.178 (Shen et al , 2017). Effects of cylinder
angle in a range of 10 -180 degrees.
The suitable angle for the vibration is 45degree because
it protects the piston pin on the behalf of the removing pins and the instalments.
And it is to will side and the more easily too inserted into the assembly. The analysis of friction characteristics for
the piston pin and the piston is connected with the connected rods. The
analysis of piston pin is based on the Multibody for the dynamic model that
supposed the oil film and the deformation. The Piston pin is the key system
during the reciprocating of the engine, which transmits the forces among the
piston as well as the connecting rods. Analysis for the piston pin is quiet
complicated, due to; the piston pin needs the system which analysed the two
bearings. The Piston pin has the 2090 nodes plus 1442 elements and the piston
has the 7089 nodes plus 5521 elements .The suitable value for friction between
the piston pin and the piston o.178 (Ba & et.al, 2015). The friction
coefficient is inversely proportional to an engine speed, where the value of
1+500/N is sued to create the friction coefficient that is decrease by ye
factor of 1.8 , where the hydrodynamic bearing friction is form the connecting
rods and the crankshaft.
Model 2: Suspension
of Kinetic analysis
In this build the suspension model of
the new car where the assumption is that the weight of body is same like 5Kg
and they also delivered the STEP files for the positions of suspensions and the
detail material is used for its assembly.
Through the use of concurrent
engineering approach we are going to plan the production of a new product that
is Automobile. This product is different on the basis of its fuel consumption
and also its engine power is better than the other cars and also it is a family
luxury car. There are many components that are involved in manufacturing the
car.
For suspension modelling of this car
the major step is to assemble the required raw materials for the production and
manufacturing of the car. There are some raw materials that are required in
bulk amount for the cost effective business strategy. These raw materials are
ordered on the basis of the automobile design. For suspension modelling of this
car its design played a very essential role because on the basis of this design
all the calculations have been made. These raw materials may include like the
steel, copper, glass, special fiber and aluminium.
There are some components that need to
be produced during suspension modelling of this car. This component includes
the chassis of this car, the engine manufacturing, interior design, the gear
box, paint on the body, the seats of the car (Gandhi et al , 2017).
Model

Model the gearbox in the
Multibody simulations and also provide the assembly of the STEP from which is
requested the maximum output of gearbox.
The frequent change in the
speed where the output is required, we used the two speed gearbox. Aim of the
report is to design the 4 gearbox by using the spur gears where the
transmission is highly efficient, that keep the gear box so economically
feasible. There are so many calculations and the verifications which place to
justify the success of designs. Important function of the gearbox is to
transmit the power which required the output for the element by changing source
of input power. (Dhawad & et.al, 2016)
