Domestic wind turbines with 1.5MW gearbox as the research object, application of virtual prototyping technology (ADAMS) simulation of dynamics of wind turbine gearbox when braking .According to research gear box structure, size and other parameters, using Pro / E software to create a solid model of wind turbine gearboxes. After importing to the ADAMS software, add the necessary constraints and loads, virtual prototype model of the gearbox is established. The simulation of dynamics of wind turbine gearbox are carried out by using ADAMS, and the angular velocity of the in-out shaft, gear meshing force and the vibration when braking cloud are obtained. That result is match with the theoretical value through analysis and the accuracy of ADAMS simulation is verified. The simulation results show that the design level of wind turbine gearboxes can be improved by using the virtual prototype technology and lay a good foundation for further design.

With the gearbox of a large-scale wind turbine as a study object, the virtual prototype model of gearbox is created based on UG and ADAMS softwares according to its design parameters such as structure and size. By rigid and flexible dynamics analysis for gearbox, the angular velocity and acceleration curves of the in-out shaft are obtained. Gear meshing forces and flexible body stress cloud using ADAMS are also obtained. It is verified that these results are coincided with the theoretical value through analysis and the simulation results of ADAMS are valid. The simulation results show that the design level of wind turbine gearboxes can be improved using the virtual prototype technology and lay a good foundation for further optimal design.

Aiming at the needs of field operations in different deep mud, a liftable crawler chassis based on the connecting rod arm mechanism was designed, including the chassis upper frame, lifting mechanism, hydraulic cylinder, limit mechanism, left and right walking system. In the ADAMS software, a virtual prototype model of the lifting and lowering chassis is established. The angle variation of the frame on the chassis relative to the ground and the angular velocity and acceleration of each lifting rod were simulated and analyzed. These rules met the chassis lifting adjustment requirements during the harvester operation.

This paper proposed a hydraulically-driven adjustable concentration of wetting agent adding device applied in underground of coal mine. A 3D model of the reversing mechanism of adding device was built by using Solidworks, and then imported to the Adams to build a virtual prototype model. The reversing mechanism was optimized by setting the model parameters, adding constraints and drive. The dynamic characteristics of the reversing mechanism were analysed under different length l of the driven rocker arm. The results show that the value of l (l=17mm) can realize automatic reversing. The simulation results provide a basis for trial-manufacture of physical prototyping and optimized design.

The article describes how we can use the virtual prototyping technology validate mechanism design of multi-joint manipulator and its grabbing performance and loading abilities per minute. It completes the three-dimensional model of virtual prototype with Solid Edge ST5, and be imported into ADAMS software. And then the manipulator kinematics simulation is carried out in ADAMS. Using the kinematics simulation technology of ADAMS, we can get the various joints in a working cycle of the displacement characteristic curve, the velocity and acceleration curves of working conditions. This paper introduces how to establish the geometric model of articulated robot virtual prototype model. And some key technology details such as adding a constraint to model are also described. Kinematics simulation analysis of the manipulator with ADAMS software can greatly shorten the design cycle, improve design accuracy and reduce the cost of product development.

According to the crane dynamics theory, the dynamical model of a bridge crane's three main mechanisms is established and the dynamical load is determined under different work conditions in the paper. The three-dimensional solid model of the bridge crane is built by Pro/E, and then which is imported in ADAMS through the interface module of Mech/Pro. The virtual prototype model of the bridge crane is formed in ADAMS when relevant constraints and loads are applied. Based on the model, the bridge crane’s kinematics and dynamics performances are simulated and analyzed, and which shows that the simulation results can provide valuable guidances for design of the bridge crane.

Background: The effective diagnosis of wind turbine gearbox fault is an important means to ensure the normal and stable operation and avoid unexpected accidents. Methods: To accurately identify the fault modes of the wind turbine gearbox, an intelligent diagnosis technology based on BP neural network trained by the Improved Quantum Particle Swarm Optimization Algorithm (IQPSOBP) is proposed. In IQPSO approach, the random adjustment scheme of contractionexpansion coefficient and the restarting strategy are employed, and the performance evaluation is executed on a set of benchmark test functions. Subsequently, the fault diagnosis model of the wind turbine gearbox is built by using IQPSO algorithm and BP neural network. Results: According to the evaluation results, IQPSO is superior to PSO and QPSO algorithms. Also, compared with BP network, BP network trained by Particle Swarm Optimization (PSOBP) and BP network trained by Quantum Particle Swarm Optimization (QPSOBP), IQPSOBP has the highest diagnostic accuracy. Conclusion: The presented method provides a new reference for the fault diagnosis of wind turbine gearbox.
