Purpose Cables are widely used, and they play a key role in complex electromechanical products such as vehicles, ships, aircraft and satellites. Cable design and assembly significantly impact the development cycle and assembly quality, which is be-coming a key element affecting the function of a product. However, there are various kinds of cables, with complex geo-metric configurations and a narrow assembly space, which can easily result in improper or missed assembly, an unreasonable layout or interference. Traditional serial design methods are inefficient and costly, and they cannot predict problems in installation and use. Based on physical modeling, computer-aided cable design and assembly can effectively solve these problems. This paper aims to address virtual assembly (VA) of flexible cables based on physical modeling. Design/methodology/approach Much research has focused recently on virtual design and assembly-process planning for cables. This paper systematically reviews the research progress and the current state of mechanical models, virtual design, assembly-process planning, collision detection and geometric configuration and proposes areas for further research. Findings In the first instance, the main research groups and typical systems are investigated, followed by extensive exploration of the major research issues. The latter can be reviewed from five perspectives: the current state of mechanical models, virtual design, assembly-process planning, collision detection and geometric configuration. Finally, the barriers that prevent successful application of VA are also discussed, and the future research directions are summarized. Originality/value This paper presents a comprehensive survey of the topics of VA of flexible cables based on physical modeling and investigates some new ideas and recent advances in the area.

In the automotive industry, arranging wire harnesses in assembly plants requires manual work. The stiffness of the high-voltage cable implies that personnel applies sufficient force on the cable to achieve a proper installation. Sometimes, the applied force is not strong enough; thus, the cable is not properly installed, or the personnel gets injured, raising ergonomic concerns that need attention. The challenges arise from the intrinsic cable characteristics such as diameter, copper type, cable strand quantity, first-layer insulator, cable insulator glue, and protective covering. The primary objective of this research is to examine how various factors, such as cable length and protective covering, impact the mechanical properties that influence the assembly of high-voltage cables. The methodology proposed consisted of characterizing the mechanical properties of the high-voltage cables in a cantilever beam test to measure deflection in response to an applied force. The measured properties were contrasted through a Finite Element Analysis of the high-voltage cable. The results validated the initial hypothesis, revealing two key findings. Firstly, the stiffness of cables varies with increasing length. Secondly, cables with tape exhibit greater stiffness than those with conduit and cables without covering, as detailed in the results section. In conclusion, extending cables without attachment points is recommended until the interfaces and environment permit. Furthermore, minimizing tape for cable protection while exploring alternative safeguards can enhance stiffness and facilitate an ergonomic installation assembly under favorable conditions. This study contributes valuable insights for optimizing high-voltage cable installation processes in assembly plants, addressing stiffness concerns through informed choices and design considerations.

The aim of this study is to ergonomically analyze a wiring harness assembly line and propose a new design to reduce the physical strain of the employees. Theory and Methods:Ergonomically unsuitable working postures are encountered in labor-intensive companies. These postures affect the performance, quality, costs, and productivity. In this study, a wiring harness conveyor line was investigated. AnyBody Modeling System was used to evaluate the stress on the muscles caused by unsuitable postures. Kinematic analyses were performed on the current conveyor line, new design and the prototype. Results:The initial analyses demonstrated high joint reaction forces in the trunk, shoulders, arms, and legs, which can cause musculoskeletal disorders. Therefore, a new conveyor line design that can reduce the physical workload on operators is proposed. The working postures in the proposed design were analyzed, and the new design significantly improved the working postures. Decrease in joint reaction forces of up to 59% in the trunk, 69% in the shoulders and 46% in the legs was detected. Conclusion:The validated conveyor was manufactured, and final analyses showed that the workload on the trunk, shoulders, arms, and legs was decreased. This produced prototype is thought to be a useful example for other similar conveyor lines.
