Finite Element Analysis of Electromagnetic Motorised Absorber System
“Finite
Element Analysis of Electromagnetic Motorised Absorber System” is my title for
my FYP..actually, the basic concept that I need to know is the suspension
system. By looking my title, the are word ‘motorized’. So it’s refer to the
vehicle. Basic things that I need to know is about the vehicle suspension
system. Novel suspension concepts are required, not only to improve the
vehicle’s dynamic performance, but also to enhance the fuel economy by
utilizing regeneration functions. In the other word, we want to improve the
suspension system. Furthermore, if we want to improve the system suspension, we need the
development of new-generation suspension systems necessitate advanced
suspension components, such as springs and dampers. So, the ultimate goal of my
FYP is to conduct feasibility study of the development of electromagnetic
dampers for automotive suspension system applications.
For your information, electromagnetic dampers are forging the way as a new
technology in vibration isolation systems such as vehicle suspension system.
Which means, this is a new development in suspension system. Based on journals
that I already read, in the system of the suspension, there are three (3)
suspension system. The first (1st) one is passive system. Secondly (2nd) is
semi-active suspension systems and the last one is active suspension system. The comparison between the three of them,they were proved that active suspension systems have superior performance in terms of
ride comfort and road-handling performances compared to their passive and
semi-active counterparts in automotive application.
Later I will story the design and development of a new
electromagnetic damper as a customized linear permanent magnet actuator to be
used in active suspension systems. So, if you all wanna know more, all of you
must follow my blog until the end of my FYP..hehehe.. Now, let me tell more
about electromagnetic. If we talk about active suspension system, we must set
in mind, it is about electromagnetic...active suspension system-electromagnetic.
My proposed electromagnetic damper has energy harvesting capability. Unlike
commercial passive/semi-active dampers that convert the vibration kinetic
energy into heat, the dissipated energy in electromagnetic dampers can be
regenerated as useful electrical energy. Although demonstrating superb
performance, active suspensions still have some issues that mus be overcome.
They have high energy consumption,
weight, and cost and are not fail-safe in case of a power break-down. Since the
introduction of the electromagnetic dampers, the challenge was to address these
drawbacks.
Because some of the weakness, hybrid electromagnetic
dampers in this my FYP are potential solution to high weight, high cost, and
fail-safety issues of an active suspension system. The hybrid electromagnetic
damper utilizes the high performance of an active electromagnetic damper with
the reliability of passive dampers in a single package, offering a fail-safe
damper while decreasing weight and cost. So, two hybrid damper designs are
proposed in my FYP.
If we think carefully, two hybrid damper design that I
proposed in my FYP, there must be passive damping. Do you want to know why? It is
demonstrated that the introduction of the passive damping can reduce power
consumption and weight in an active automotive suspension system. The ultimate
objective of my FYP1 is to employ existing suspension system and damper design
knowledge together with new ideas from electromagnetic theories to develop new
electromagnetic dampers. For the very first time, the eddy
current damping effect is introduced for the automotive suspension
applications.
To achieve the defined goals, numerical simulations, Finite
Element Analysis (FEA) using ANSYS software will be conducted. This simulation
should be done by FYP2 but my supervisor want me do it in FYP1. Dr Razlan told
me to get the drawing and graph if possible. Dr Razlan don't want to start the
analysis at the next semester because many students will take a long time not
to analysis, but to start analysis...I still not explore yet this ANSYS’s
software because I'm right now focusing to write the methodologies.
What I did is only small portion of the growing research in
automotive area, and it is hoped that the results obtained soon will lead to
the realization of a safe and more superior automotive suspension system. Actually
this electromagnetic suspension system is still a new thing in automotive
suspension system. That’s all...this is a little bit about the introduction of
my FYP that I can share to all of you..if you all wanna know in details about
my FYP, wait for my next update..wait yaaaa!!
