“…In order to study the motion characteristics of multi-body structures, Baiceanu [9], Hideki [10] and Kimata [11] established the contact models of a multi-body system, and researched the influencing factors of the contact force response. Berjoza D [12], Mondragon-Parra E [13] and Feng H [14] established the multi-body dynamics model of the automobile transmission system, and analyzed the influence of the hinge angle, the number of balls, and the track offset on the contact force. Nogi T [15], Choe B [16,17], Qi Z H [18], and Yamamoto T [19] analyzed the dynamic characteristics of the ball cage universal joint of the automobile drive shaft through multi-body dynamics simulation, and obtained the isokinetic characteristics of the universal joint and the variation law of the universal joint deflection torque.…”

The flexible joint is an important part in ultra-short-radius drilling tools, and its structural parameters and motion characteristics are key factors affecting the success of drilling. In this work, a new type of ball cage flexible joint, which is applied in 5″ and 5.5″ cased wells, was proposed based on the working principle of the ball cage universal joint. A structural parameter design method for the ball cage flexible joint was established according to the geometric coordination relation and material strength theory. Using this new method, the length, diameter, and window size of the ball cage flexible joint were analyzed. The multi-body motion process was further analyzed using a multi-body dynamics method, and then the motion characteristics, such as impact contact force, isokinetic characteristics, transfer efficiency, deflection torque and so on, were studied. Based on the above analyses, the structural parameters of the designed joint were optimized by means of the orthogonal test method. Results demonstrate that the experimental ball cage flexible joint has excellent isokinetic transmission characteristic, which can effectively suppress vibration and shock caused by changes in rotational speed. The transmission efficiency of the structure was 89.8%, while the power loss rate was 0.102%. According to the orthogonal test analysis, the optimal structure of the flexible joint has a ball seat diameter of 80 mm, a ball head diameter of 62 mm, and a ball key diameter of 16 mm. It is important to note that the ball key diameter was the most influential factor on the flexible joint internal contact force. The ball key contact force varied periodically, and there was a significant phase difference between the contact forces of different balls. On the other hand, with an increase in the flexible joint working angle, the deflection torque increased gradually, and the vibration amplitude of the torque increased. This work can provide reference for the parameter optimization design of the new flexible joint.

“…More research directions related to this topic involve numerical simulation of R-CVJ, 18,19 internal contact forces analysis and transmission efficiency analysis. [20][21][22] A novel double-deck R-CVJ (DR-CVJ) mechanism configuration with large operating angle is presented in this paper, considering the actual engineering requirements of small installation space, large working angle, and constant speed transmission. The mechanism is based on an integrated coupling design of a kinematic chain of two R-CVJs (inner and outer R-CVJs) in series to achieve a large operating angle and uses a constraint branch to determine the distribution of the swing angle between the inner and outer R-CVJs.…”

Considering existing Rzeppa joints’ small operating angle, this research aims to explore a new ball-cage joint mechanism configuration with large operating angle while preserving Rzeppa joints’ kinematic characteristics, yielding novel double-deck Rzeppa constant velocity joints (DR-CVJs). An integrated coupling design method for a series kinematic chain of two Rzeppa joints is proposed, and a new ball-cage joint initial configuration is established. By introducing a constraint branch, a single mapping between input and output is established, and the novel DR-CVJ mechanism configuration with large operating angle is constructed. The degree-of-freedom properties of the DR-CVJ mechanism are assessed using the screw theory. The maximum operating angle’s constraint conditions of the DR-CVJ mechanism are given, and its working space is drawn. The kinematic solution of the DR-CVJ mechanism is obtained, and kinematic simulations are performed. The results show that the principle of the novel DR-CVJ mechanism configuration is feasible, its effective maximum operating angle can reach 60°, its kinematic characteristics are consistent with those of the existing Rzeppa joints, and the proposed DR-CVJ mechanism configuration has engineering development potential.

“…At the initial stage, the automobile transmission system is mainly designed using formalized software. For instance, multi-body dynamics software can be used to calculate the natural frequency and mode of automobile transmission system [2], and it can also be used to analyze the contact forces and transmission efficiency of automobile universal joints [3]. This kind of formalized software, however, is more like a black box, which is not suitable for intelligent design.…”

Intelligent manufacturing is developing rapidly nowadays, promoting the efficiency of manufacturing. In comparison, the design process has become a bottleneck in the product life cycle. In order to address this problem, this research develops an intelligent design method based on the automobile transmission system. Firstly, a mathematical model of the coupled vibration between the drive shaft and the main reducer was developed, and the vibration responses of the transmission system were simulated based on this mathematical model. Then, a test rig was developed to measure the vibration responses of the system; the measured results correlated well with the simulation results, indicating that the mathematical model can be used to investigate the coupled vibration between the drive shaft and the main reducer. Furthermore, the multiple parameters of the transmission system were optimized based on the mathematical model using the intelligent optimization algorithm. In particular, software was developed based on the intelligent optimization algorithm for the convenience of analysis, and the optimized results were acquired. The analysis results show that the vibration responses can be reduced when the optimized parameters are applied, indicating that the intelligent design method developed in this research is effective for the intelligent design of transmission system.
