Planet Carrier

Taking a planetary reducer in an electric vehicle as the object of study, a rigid-flexible coupling model was established to perform the dynamics simulation. The variational regularities of the meshing forces, output speed and acting forces of bearings were obtained, and then a finite element analysis of the planet carrier was carried out. This method can not only solve the problem of the boundary conditions of planet carrier which are difficult to define in finite element analysis, but also improve the accuracy of analysis results when the influence of carrier flexibility on the whole system is considered in dynamics simulation, which lays the foundation for further research on reducers.

In this paper, a certain type of vehicle missile launching system is the research object, which uses CAE technology to make a flexible coupling system dynamics simulation and analysis to provide a reference for similar tests. Since the complex structure of the vehicle missile system, reasonable assumptions and simplifications are made in establishing the dynamics model. Pro/E is used to build the three-dimensional model, and then it is imported to the ABAQUS to establish its dynamics model. Finally, in a complete virtual prototyping system model, we make a simulation of working conditions, and draw conclusions and analysis. The results show that the use of independent dynamics rigid-flexible coupling model dynamics simulation based on ABAQUS can be more realistic simulation of the process of vehicle missile launch, and it verifies the results of different working conditions, which provides a reference for the vehicle missile launching systems simulation .

Mining Height

With the increase of mining height, the problem of coal wall spalling in the working face gradually worsens. Hydraulic support and its face guard structure are the key pieces of equipment to restrain the coal wall spalling. However, at present, the hydraulic jack is mostly considered as rigid in the analysis of protection mechanism. This simplification cannot effectively reflect the true bearing state of the face guard. In order to improve the accuracy of analysis, this study considers the face guard jack as a flexible spring and establishes a rigid-flexible coupling analysis model of the face guard mechanism. First, based upon the multibody dynamics software ADAMS®, the multibody numerical model of the face guard of the hydraulic support was established. The influence of the two kinds of structures on the coal wall disturbance was analyzed and compared. Then, the rigid model was meshed. The hydraulic jacks were equivalent to the spring system, and the rigid-flexible coupling model was established. Based upon the application load on different positions of the rigid-flexible model, the load-bearing characteristics and hinge point force transfer characteristics of the two face guards were analyzed. The results show that the support efficiency of the integral type was higher than that of the split type. In the vertical support attitude, the dynamic disturbance of the coal wall, produced by the two kinds of face guards, was small. The four-bar linkage effectively improved the ultimate bearing capacity of the integral face guard. The results provide theoretical support for the design and optimization of the face guard.

Sliding Guideways

A rigid-flexible coupling model of sliding guideway working in powered turret for a new developed multifunction NC lathe is built up based on Solidworks, ANSYS and ADAMS. A solid model of is built up by the 3d-Modeling software Solidworks, and then the built model of sliding guideway is imported into finite element analysis software ANSYS to analyze elastic deformation. A mnf file of model generated by ANSYS which is a flexible body is fed into ADAMS to replace the rigid body of assembly. A dynamics simulation is conducted by considering a typical cutting processing like milling on lathe, the deformation of fixed guideway in working condition is checked. The analyzed results show that it is more rational and accurate to apply rigid-flexible coupling dynamic simulation for analyzing such mechanical system and this type of sliding guideway used in powered tool turret can stand up with cutting load and can meet the requirement.

This paper mainly investigated the rigid-flexible dynamics simulation method of multi-body system. The 3-RPS parallel robot dynamics model is created by ADAMS (multi-body dynamics software) and ANSYS (finite element analysis software). In accordance with the flexible-body theory, we analyzed mechanical characteristics of parallel robot with no-load or full-load working condition, and got the deformation of end measuring point, maximum stress position and dynamics stress curve. The analysis method is more intuitional and accurate, and can increase the accuracy of dynamic response analysis of links under the dynamic loads. The simulation results create conditions for structure design and optimization of 3-RPS parallel robot.

This paper develops a rigid-flexible coupling approach to predict the dynamic performance of the excavator, including the stress distribution and stress diagram of curves. In order to study the dynamic performance of the excavator during the mining process, the rigid-flexible coupling model of a excavator is established and carried out for dynamics simulation. The results show that the strength of excavator meets the expected requirement and there is a large optimization space. In order to reduce the mass of the excavator's boom, this paper optimizes the design of the boom. Based on the results of the optimization design, the rigid-flexible coupling simulation of the excavator was performed again, which verified that the strength of the boom is sufficient. Simulation results show that the virtual prototype software can effectively predict the dynamic performance of the excavator. This paper provides a solid foundation for further study of the lightweight design of the whole excavator component.
