In [24], the Levenberg-Marquardt algorithm is proposed to solve the cable model under the condition of constraints imposed at both ends; however, this algorithm may cannot guarantee numerical convergence of the cable model under complex conditions. Thus, in this study, the algorithm is improved by using the trustregion method to ensure that the theoretical model of the cable in contact with a curved surface has good numerical stability.…”

“…Owing to its simplicity, the Kirchhoff cable mechanics model is currently widely used [15][16][17][18][19][20][21]. By implementing the Kirchhoff theory and elastic thin rod static model [22], Liu et al [23][24][25] developed a cable mechanical model with smooth plane contact to improve the virtual reality assembly technology for cables. Although their model is useful, they ignored the effects of gravity on the cable; moreover, the contact between the cable and curved surface was not considered.…”

“…In addition, it can only be employed to solve the initial value problem and cannot be employed to estimate the actual working conditions. Based on previously reported theoretical results [22][23][24][25][26], the effects of gravity and friction on the cable are considered to propose a nonlinear mechanical model of a cable under localized constraints of a curved surface in this paper. When implementing multi-physics coupling methods, the gravity force distribution on the heavy cable, which is determined by the safety shield, is an important factor that should not be neglected.…”

A nonlinear model of a special cable in space robotic arms is developed in space environment. The mechanic effects of control cables in powerful robots can often be neglected. However, in complex space multi-physics environments, involving ultra-low temperature, radiation, and other extreme conditions of outer space, the externally mounted cables (protected by shielding layers) can induce strong nonlinear interference to robot arms; and this can induce further small-range slow rotations or oscillations of the flexible joint of robots at a specific posture, which consequently affect the precision and operation performance of end effectors. Effective mathematical models on nonlinear mechanics of strong cables under multi-physics environments and their effects on weak robots have not been well developed yet. Complex key factors, such as low gravity, nonlinear friction, and unexpected curved surface constraints, have not been extensively investigated either. In this study, considering all these key factors, a Kirchhoff nonlinear mechanical model of cables in

“…In sensor applications, these cables must not only meet electrical connection requirements but also adapt to various complex motion environments during engine operation. Motion cables are a special category that move in synchronization with the connecting parts during the use of the product among the various types of cables [ 4 ]. Presently, the process design of motion cables faces challenges related to poor wiring process reliability and cable bending fatigue.…”

Motion cables, which are widely used in aero-engine sensors, are critical components that determine sensor stability. Because motion cables have unique motion characteristics, the study of their mechanical properties and reliability is very important. In addition, motion cables are complex in structure and cannot be applied to conventional fixed cable research methods. In this study, a new approach is proposed to introduce the theory of anisotropic composites into a simplified cable model, so that the cable is both physically conditioned and has good mechanical properties. While applying the theory of anisotropic composites, the forces of tension and torsion are considered in a motion cable under the combined action. In this context, the reliability of the structure is the fatigue life of the cable. In this paper, the mechanical properties and fatigue life of motion cables are investigated using the finite element method at different inclination angles and fixation points. The simulation results show that there is a positive correlation between the inclination angle and the extreme stress in the motion cables, and the optimal inclination angle of 0° is determined. The number of fixing points should be reduced to minimize the additional moments generated during the movement and to ensure proper movement of the cables. The optimal configuration is a 0° inclination angle and two fixing points. Subsequently, the fatigue life under these optimal conditions is analyzed. The results show that the high-stress zone corresponds to the location of the short-fatigue life, which is the middle of the motion cables. Therefore, minimizing the inclination angle and the number of fixing points of the motion cables may increase their fatigue life and thus provide recommendations for optimizing their reliability.
