One of the innovative and passive methods to reduce offtracking in tractor-semitrailers is to implement a Split fifth wheel coupling (SFWC). Studies show that off-tracking is reduced by up to 21% for a circular turning manoeuvre. The handling performance of the tractor-semitrailer with SFWC is not evaluated yet and hence needs to be ad-dressed. In the present work, in order to assess the handling performance of the vehicle with SFWC, simulations are carried out for ISO double lane change manoeuvre at various speeds. The results are compared with those of the Conventional fifth wheel coupling (CFWC) model to understand the relative performance of the tractor-semitrailer with SFWC. The results show that the performance of tractor-semitrailers with SFWC is on par with that of vehicles with CFWC at lower speeds; in fact, for speeds below 40 kmph, the lateral acceleration experienced by the semitrailer of SFWC vehicle is less compared to that of CFWC vehicle. However, it becomes a little unstable at higher speeds. With the development of stability control systems like Electronic stability control (ESC), optimized for tractor-semitrailers with SFWC, their performance would improve.","PeriodicalId":431921,"journal":{"name":"Proceedings of the 10th ECCOMAS Thematic Conference on MULTIBODY DYNAMICS","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123080724","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the complex structure of cables usually consisting of con-centric layers of intertwined wires, shields and the outer jacket, inelastic deformation behaviour has to be expected. In this work, we model simpliﬁed cables as strands of helix wires discretised with quadratic beam elements to investigate the inﬂuence of geometric parameters such as the helix angle of the wires and the interactions of the wires by means of frictionless or frictional contact models. Starting at low model complexity, we use double wire and seven wire models to simulate pure bending of intertwined strands omitting material inelasticity to avoid superposition of structural and material effects. Different variations of contact states in the undeformed conﬁguration of the seven wire strand are taken into account allowing for the direct observation of the inﬂuence of active contacts on the strand’s bending response. First steps towards modelling the interactions between wires and objects relevant in cable bundle assembly, e.g. cable ties or clips, are presented for the double wire model. The presented models yield a valuable toolbox for the investigation of speciﬁc structural parameters affecting the deformation behaviour of cables.","PeriodicalId":431921,"journal":{"name":"Proceedings of the 10th ECCOMAS Thematic Conference on MULTIBODY DYNAMICS","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128314284","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
