Virtual Prototyping with Rigid Body Concept for the Development of
Internal Combustion Engine 2018-01-5013
The recent surge in the demand for the virtual application has led to the need
for prototype testing that control the associated problem to a great extent.
Consequently, a reduction in the costs of operating the actual prototype is
envisaged. However, in some cases, just by adjusting input parameters alone
could increase the success rate of these prototypes. During the design process,
the functional prototyping is mainly used to evaluate the appearance of product
and simulate its system level functioning. Multi-body dynamics analysis involves
the simulation of rigid body systems under the application of forces or motions.
Virtual prototype can substitute the physical prototype to perform a system
level functioning of the product. The Internal combustion engine mechanism is
considered for simulating the system level working with real time dynamic
responses. Virtual prototype is created with a rigid body concept for an
existing four stroke, single cylinder internal combustion engine mechanism to
visualize the system level functioning and to find the displacement, velocity
and acceleration of the piston on account of validation of the actual
functioning of the engine. Virtual engine created by modeling individual parts
of the product using CAD software and is simulated by using Hyper-Works computer
aided engineering (CAE) tool. Finally, the validation of the functioning of the
engine is done by comparing the results obtained by mechanism response
(slider-crank mechanism; idealized for an internal combustion engine) of the
engine using real time operating data collected experimentally.
