“…The motor was connected to the input of the input axis, where the input axis torsional stiffness was 1 and the input torque of the motor was 0 . The output axis torsional stiffness was 3 and the resistance torque of the output load was 5 . The rotational inertia of the four gears of the gear system was 1 , 2 , 3 , and 4 .…”

“…Junguo Wang [5] studied the torsional vibration model of a singlestage spur gear drive system, analyzing the effect of stiffness on the dynamic behavior of the locomotive gear transmission system. Lassâad Walha [6] and Kamel Abboudi [7] established a 12-DOF nonlinear dynamic model for the two-stage gear system, only considering the gear system itself without the effects of input and output in the model.…”

For the nonlinear disturbance actual issues of the model space drive mechanism two-stage spur gear system, a nonlinear dynamic model of 14-DOF (degree of freedom) two-stage spur gear with time-varying stiffness and damping was established. This model has been developed previously by the authors to access the large inertia on the dynamic response of spur gear space driving mechanism, and its effectiveness was proved by a motion simulation experiment. In this paper, the profile error (PE) and the index error (IE) were enhanced in the dynamic model. The effects of profile error, index error, and variable load torque on transmission error (TE) were analyzed, while the optimization was proposed according to the analyzed result. The peak-to-peak value of the optimized load transmission error (LTE) was reduced by 60.7%, which improved the transmission accuracy and reduced the phenomenon of disturbance. The research of nonlinear dynamical model of two-stage spur gear and the TE of the large inertia load were enriched, which provided an important reference for the actual design of the gear system.

In order to solve the problem of the dynamic matching of the step less transmission system, the power machine step less transmission on the electric vehicle was studied. The double motor was used as the power source. The main motor M1 mainly provided the driving force. The speed regulating motor M2 was used to adjust the output speed. The speed range was wide, and the quality was light. The system flexibility was high. The basic performance of the permanent magnet synchronous motor for vehicle was introduced. According to the actual design requirements, the transmission scheme was selected, and the transmission principle was designed. The corresponding characteristic parameters of the transmission system were calculated. According to the driving demand under different working conditions, the control structure of the step less transmission system was designed. The test bench was built to test the power machine step less transmission. According to the working point and resistance load at different speed, the test bench was driven and loaded. The characteristic data of the transmission system in the stable running state were collected and analyzed. The results showed that the step less transmission system had stable step less speed regulation. Therefore, the method provides high transmission efficiency.

“…The design of motion profiles of machine elements has been widely studied in research areas such as mechanical engineering and control engineering. Commonly, the transmission chain between the actuator coordinate, commanded by the user, and the coordinate that describes the desired motion, is linear (pulley belt [1], gear chain [2], rack and pinion, etc.) ( Figure 1).…”

This paper proposes an analytical solution of the Inverse Kinematics (IK) problem at dead point configurations for any planar one degree of freedom linkage mechanism, with regard to the continuity C n of the motion law. The systems analyzed are those whose elements are linked with lower pairs and do not present redundancies. The study aims to provide the user with some rules to facilitate the design of feasible motion profiles to be reproduced by conventional electrical actuators at these configurations. During the last decades, sev- eral methods and techniques have been developed to study this specific configuration. However, these techniques are mainly focused on solving numerically the IK indetermi- nacy, rather than analyzing the motion laws that the mechanisms are able to perform at these particular configurations. The analysis presented in this paper has been carried out differentiating and applying l’Hôpital’s rule to the system of constraint equations / ð q Þ of the mechanism. The study also considers the feasibility of the time-domain profiles to be reproduced with conventional electrical actuators (i.e. AC/DC motors, linear actuators, etc.). To show the usefulness and effectiveness of the method, the development includes the analytical application and numerical simulations for two common one degree of free- dom systems: a slider-crank and a four linkage mechanisms. Finally, experimental results are presented on a four linkage mechanism test bed.Postprint (author's final draft
