For example, as shown in fig. 5, for a client-side simulator, i.e. a user corresponds to a department attribute one by one, i.e. one simulator belongs to one department, one department may have one or more simulators, a role corresponds to a permission attribute one by one, a role permission determines an automation module that can be obtained by the role, a system administrator gives the simulator a role, and one role may correspond to a plurality of simulators.

For example, in the version update software interface of the automated simulation platform system shown in fig. 8, a system administrator updates the system at the host end, and after a simulator logs in at the client end of the simulator, if the automation module has update content in the authority of the simulator, the system prompts the simulator to update the automated simulation module at the client end of the simulator.
For the specific process of step S21 and step S24, reference may be made to the corresponding content disclosed in the foregoing embodiment, and no further description is given here.
From the above, according to the information of the simulator carried in the simulation request, determining the role corresponding to the simulator client, and according to the role, determining the authority of the simulator client. The corresponding automatic simulation module can be sent according to the self business requirements of different departments and role simulation personnel, and the efficiency and the safety of issuing the simulation module are improved. And updating the local automatic simulation module, judging whether the target automatic simulation module corresponding to the authority of the simulator is the latest version or not after the client of the simulator logs in, and if not, sending a version update prompt to the client of the simulator so that the client of the simulator can timely know and update the local automatic simulation module to timely update the version.

For example, the strength simulation for a vehicle body structure is divided into 4 processes including pre-processing, including geometric processing and finite element generation, imparting finite element material properties, loading calculations according to standards, result viewing, and reporting. For pretreatment, due to the structural similarity of different vehicle bodies, a plurality of similar operations exist in the pretreatment process, the operation characteristics in the operations are extracted, for example, the filling of process holes, the effect of the process holes with the diameters smaller than R on the calculation result is very little, and a plurality of process holes on the structure can be removed at one time by a preset programming method, so that the efficiency is improved. For the assignment of the material characteristics of the finite element materials, a grading naming rule of the structural components of the vehicle body, such as an Underframe outer beam, an underwrame_OuterBeam_T4_HT, is preset, material characteristic information in naming is matched through a programming method, the underwrame indicates that the outer beam is a part belonging to the Underframe of the vehicle body, the Outerbeam indicates that the outer beam is named, T4 indicates that the thickness is 4, and the HT indicates that the adopted material is HT-type stainless steel, so that the automatic assignment of the material properties can be realized.

Step S32: and generating corresponding programming processing instructions based on the operation characteristics, and obtaining automation simulation modules of different disciplines based on the programming processing instructions so as to obtain an automation simulation platform system based on the automation simulation modules.
In this embodiment, after the operation features are obtained, corresponding programmed processing instructions are generated based on the operation features, and automated simulation modules of different disciplines are obtained based on the programmed processing instructions, so as to obtain an automated simulation platform system. Namely, corresponding programming processing instructions are generated according to the extracted operation characteristics so as to normalize the CAE simulation process, and the working efficiency is improved through a programming method. And (3) obtaining the automatic simulation modules aiming at the components in different disciplines according to the programmed processing instructions, developing the automatic simulation modules of each discipline, promoting the cooperation among the disciplines, and strengthening the support for product research and development. Such as the structural strength and vehicle dynamics disciplines illustrated by way of example in fig. 7, an automated simulation module that includes collision analysis, body structure, and bogie structure. Finally, the automatic simulation platform system is obtained based on the obtained automatic simulation modules of the different parts under different disciplines.
Step S33: and receiving a simulation request sent by a simulator client.

The specific processes of the steps S33, S34, and S35 may refer to the corresponding contents disclosed in the foregoing embodiments, and will not be described herein.
