The importance of this study arises due to the unidirectional torsional properties of a wire rope. For an effective operational LSRS, the wire ropes need to have similar angular deflection in both the clockwise and anti-clockwise direction. LSRS, an integral component of the SAS is a flexible shaft that can replace the conventional rigid shaft of the steering system and allows active control to be performed. 3D solid models of the simple strand and the 4 strand wire ropes used in finite element analysis were generated in CAD software SolidWorksTM. The single strand and the different configuration of wire ropes required to function the LSRS effectively were then analyzed using Finite element simulation in ANSYSTM. A single wire rope could not be used because its construction has inconsistency in the torsional stiffness in clockwise and anti-clockwise direction. The single-strand right-direction lay wire rope is found to have 16.05 angular deflection percentage difference in the clockwise and anticlockwise directions which indicates that using a single strand wire rope for the LSRS will cause the vehicle to have a variable response in the clockwise and anti clockwise direction upon turning the steering wheel. Due to this inconsistency, two variations namely Variation 1 and Variation 2 with arrangement of 4 strand wire rope were devised so that the angular deflection percentage difference would be negligible. Simulation results indicated that Variation 1 of the two variations with an angular deflection percentage difference of 0.34 in the clockwise and anti-clockwise direction respectively is best suited for the use in LSRS as it has almost negligible angular deflection percentage difference and will allow the vehicle to have similar steering response in the clockwise and anti-clockwise direction. © 2016 The Authors, published by EDP Sciences. date: 2016 publisher: EDP Sciences official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-84987811637&doi=10.1051%2fmatecconf%2f20167400017&partnerID=40&md5=b4b82391a44b476fe416bceb50fa6634 id_number: 10.1051/matecconf/20167400017 full_text_status: none publication: MATEC Web of Conferences volume: 74 refereed: TRUE issn: 2261236X citation: Hussain, N. and Baharom, M.B. and Maharun, M.
