Prestasi kereta api berkelajuan tinggi sebahagiannya bergantung kepada kecekapan sistem
pengumpulan elektrik dan ianya juga bergantung kepada kestabilan interaksi antara wayar
sesentuh dan pantograf. Semasa kereta api beroperasi pada kelajuan tinggi, sistem pengumpulan
elektrik ini mengalami variasi daya sentuhan. Oleh kerana variasi daya sentuhan yang berterusan
di mana ada keadaan pantograf tidak menyentuh wayar sesentuh, percikan api akan terhasil dan
kecekapan sistem pengumpulan elektrik terjejas. Oleh yang demikian, variasi daya sentuhan ini
perlu dikawal agar sentiasa konsisten. Penyelidikan melibatkan reka bentuk kawalan pantograf
aktif melalui simulasi komputer. Kajian interaksi sifat dinamik wayar sesentuh dan pantograf
dilakukan pada kelajuan dan ketegangan yang berbeza. Lantunan pantograf dan anjakan wayar
sesentuh selepas berlakunya sesuatu fenomena dikaji. Penyelidikan akan merangkumi pembinaan
permodalan dan simulasi menggunakan teknik permodalan yang sesuai. Pembinaan ini
memerlukan pembuktian persamaan matematik terhadap elemen sifat dinamik pantograf tersebut.
Model matematik dan simulasi ini akan dibangunkan menggunakan perisian komersial sedia ada.
Penyelidikan juga melibatkan pembangunan reka bentuk sebuah pelantar ujian untuk pantograf
bagi mengenal pasti parameter fizikalnya pada keadaan stabil dan seterusnya membolehkan
eksperimen getaran bebas untuk kekangan rasuk pada pelbagai frekuensi sinusoidal dijalankan.
Keputusan eksperimen akan dibandingkan dan dikaji. Kesimpulannya penyelidikan ini akan
dihasilkan melalui analisis sifat dinamik pantograf yang mempunyai kawalan aktif melalui
simulasi komputer. Keberkesanan kawalan aktif dalam mengekalkan daya sentuhan yang optimum
dan peningkatan prestasi sistem pengumpulan elektrik akan dicapai.
The performance of a high -speed train depends in part on the efficiency of the electrical collection system
and it also depends on the stability of the interaction between the contact wire and the pantograph. When
a train is operating at high speeds, this electrical collection system experiences variations in contact force.
Due to the constant variation of the contact force where there is a condition the pantograph does not
touch the contact wire; sparks will result and the efficiency of the electrical collection system is affected.
Therefore, this variation of tactile force needs to be controlled to be consistent. The research involved the
design of active pantograph controls through computer simulations. The study of the interaction of the
dynamic properties of the contact wire and the pantograph was performed at different speeds and
tensions. Pantograph bounce and contact wire displacement after the occurrence of a phenomenon are
studied. Research will include capital construction and simulation using appropriate capitalization
techniques. This construction requires proof of mathematical equations to the elements of the dynamic
properties of the pantograph. These mathematical models and simulations will be developed using
existing commercial software. The research also involved the development of the design of a test rig for
the pantograph to identify its physical parameters at stable conditions and in turn allow vibration -free
experiments for beam constraints at various sinusoidal frequencies to be carried out. The experimental
results will be compared and studied. In conclusion this research will be produced through analysis of the
dynamic properties of pantographs that have active control through computer simulations. The
effectiveness of active control in maintaining optimal contact force and improved performance of
electrical collection system will be achieved.
A high-speed train's performance is determined in part by the efficiency of the electrical collection
system, as well as the stability of the interaction between the contact wire and the pantograph. This
electrical collection system experiences variations in contact force when a train is travelling at high
speeds. Sparks will occur as a result of the constant variation of the contact force where the
pantograph does not touch the contact wire; the efficiency of the electrical collection system will
suffer as a result. As a result, in order to maintain consistency, this variation in tactile force must
be controlled.
