Abstract: This research work presents a dynamic control of a 8 – Degrees of freedom (DOF) based bio-inspired humanoid robotic arm which was simulated using MATLAB / Adams Co-Simulation environment. The robotic arm has been modeled using PRO-E and its invoked in ADAMS and Controlled by MATLAB programming environment. With the help of the simulation results, parameters like torque, position, etc of the system have been analyzed for various trajectories or path of the robot and the results have been discussed in detail. This research work is part of a real time humanoid robot project titled – RALA (Robot based on Autonomous Learning Algorithm).

Abstract: To improve the design efficiency of the Integrated braking system (IBS) based on dual-motor drive, the paper established a co-simulation model in ADAMS and Simulink. The 3D mechanical model which was set up in SolidWorks had been imported into the ADAMS software to build the retarding mechanism model, and build the motor model in Simulink, the established model was used to co-simulate the brake pressure regulation process. The results show, the system has a fast pressure response characteristics, and the single wheel cylinder pressure regulation frequency can reach 50Hz. The paper provides an effective method to design an IBS prototype.

Taking great advantage of Pro/ E and ADAMS, the mechanism motion curves and value obtained through this method to verified the feasibility and reliability of the design.

Abstract: This paper mainly focuses on the modeling and simulation of a three-DOF high-speed parallel robot which is widely used in the design of an enterprise vials testing equipment. For high-speed parallel manipulator rapid modeling and collaborative simulation, we study the two methods. One approach is to transfer the 3D SOLIDWORKS model into MATLAB/ SIMULINK model. Another method is to convert the three-dimensional model of SOLIDWORKS models into ADAMS. ADAMS and SIMULINK work together as a simulation platform. The results show that the two methods could provide the efficient and significant simulation platform to research the control strategy of High-speed parallel manipulator.

According to the robot's tilt problem, this paper guarantees the level of tree-pruning robot using the method of controlling the motor speed at different locations. This paper establishes a three-dimensional virtual prototype model about tree-pruning robot in ADAMS software, design controller in Matlab software, and conduct ADAMS-Matlab co-simulation. The simulation results and experimental prototypes show that the designed control method can effectively overcome the tilt problem in the crawling process.

By calculating, analyses and assess are made of the bridge when trains are moving at different speeds. Results provide theoretical support and refer to the same type of bridge design.

Abstract: In order to further improve the baking energy recovery rate of extended-range electric vehicle (E-REV), thus to extend driving distance, a high efficiency regenerative braking control strategy for E-REV was proposed. Based on the co-simulation platform with AVL-Cruise and Simulink, a dynamic model for E-REV was set up and simulation calculations on hybrid motor-mechanical regenerative braking were performed. The simulation results with typical driving cycles illustrate that the friction braking force and the regenerative braking force could be well integrated, braking energy recovery efficiency was high, and the proposed control strategy of regenerative braking in the paper is effective.

Abstract: The basic configuration and operation modes of the series extended-range electric vehicle were analyzed and a new method of engine choice and fuel economy evaluation was proposed. A co-simulation platform is set up with Cruise and Matlab/Simulink to evaluate the rule-based engine on-off and optimal operation line control strategies. The simulation results with typical driving cycles illustrate that: firstly, the engine on-off control strategy makes engine and generator operate on their best efficiency points, and its fuel economy is better than optimal operation line control strategy; secondly, when the optimal operation line control strategy is adopted in Extended-Range Mode, the engine downsizing will be beneficial and the extended-range electric vehicle (E-REV) will achieve a better fuel economy and control effect.
