Description

Technical Field

[0001] The present invention belongs to human-machine environment system engineering technology, relates to the technical field of special equipment human-machine engineering design and analysis, and particularly to a human-machine environment engineering analysis system and method based on three-dimensional flow field numerical analysis. Background Art

[0002] Human-machine environment system engineering is a discipline established to study various issues related to machine system design and the human body, to study the interaction between humans, machines and the environment, and to optimize the working efficiency of the entire human-machine system. It involves the comprehensive application of many disciplines such as metrology, physiology, dynamics, fluid mechanics, and biomechanics. At present, computer-aided design and manufacturing are widely used in various disciplines, greatly improving production and design efficiency. However, the human-machine environment engineering software currently used is mainly foreign software, which is mostly used for visualization, accessibility analysis, and operation force analysis, and has high application costs. Guided by the direction of foreign software, the multi-factor coupling analysis technology of human-machine environment system engineering as a comprehensive discipline application is difficult and has a high threshold, especially for the design and analysis of special equipment human-machine environment engineering. No relevant computer-aided design tools have been found that can simultaneously perform human characteristics analysis, machine characteristics analysis, human-machine relationship analysis, human-environment relationship analysis, etc., and it is impossible to achieve comprehensive inspection and optimization of human-machine engineering in advance, thereby solving the problem of time-consuming, labor-intensive and inefficient human-machine engineering verification in the later stage.

[0003] With the advancement of science and technology, the idea of ​​ergonomics has also been widely recognized. In the field of advanced manufacturing represented by aerospace, weapons and equipment, and the automotive industry, the idea of ​​realizing human-machine environment system engineering through computer simulation basically runs through the entire design and manufacturing process. Human-machine environment system engineering includes measurement, operation, environment, and the human-machine integration, human-machine security, and safety of use around these, which require different professional software to complete. The JACK and RAMSIS software currently used for ergonomic design are mostly used for space verification, field of view verification, and comfort verification including operating force and accessibility. It is difficult to cover the impact analysis of temperature, humidity, air pressure, harmful gases, etc. on people in the operating environment. In addition, the software is developed by foreign companies, which is expensive and cannot be modified according to needs.

[0004] Therefore, how to change the previous practice of only being able to obtain single-point environmental parameters and being unable to meet the overall environmental parameter design and analysis needs in human-machine environment system engineering, especially the multi-factor comprehensive simulation of the human-machine environment of special equipment, and reduce the application cost of simulation technology, is a technical problem that needs to be urgently solved in human-machine environment engineering.

[0032] An embodiment of the present invention provides a comprehensive simulation system for special equipment human-machine environment engineering analysis, including:

[0033] According to the requirements of human-machine environment design and analysis of special equipment, the analyzed object is analyzed to extract human-machine environment data corresponding to the simulation elements, including: the various components of the object, the connection relationship between the components, the position of the human body, the physiological state, and the environmental parameters and equipment parameters corresponding to the simulation model. Among them, the various components, the connection relationship between the components, and the position of the human body belong to the simulation elements corresponding to the simulation model, while the physiological state, the environmental parameters corresponding to the simulation model, and the equipment parameters belong to the simulation elements corresponding to the simulation parameters.

[0034] According to the extracted human-machine environment data corresponding to the simulation elements and analysis requirements, it is preferred to perform fluid mechanics simulation analysis or directly enter the analysis and evaluation function.

[0035] According to the simulation element analysis, based on the basic geometric structure, a full three-dimensional model is established, the equipment shape, the space where the personnel are located, and the interactive device are retained, the model is simplified, the basic parameters and connection relationships of each equipment in the model are set, and the calculation domain is determined, and the boundary conditions are set to form a simulation model for simulation analysis. The present invention designs and constructs a typical wheeled equipment model and calculation examples based on experience. If similar equipment analysis or qualitative analysis is performed, the model of the present invention can be called for simulation analysis.

[0036] Conduct quantitative analysis on the global parameters of the computational domain, set up test and measurement data monitoring points in the personnel's near-body space, obtain global human-machine environmental engineering data on the analyzed object, such as temperature, humidity, and harmful gases in the environment, study the complex factors that affect the human body in the vehicle, conduct parametric analysis on the equipment, or import the results into the evaluation module for analysis and evaluation.

[0037] Through the system interactive interface design, the simulation model, fluid simulation, and analysis and evaluation module parameter interactive windows are established. In the simulation module, the corresponding simulation model and simulation parameters are called or constructed to obtain the human-machine environment engineering data such as human-machine shape, temperature, humidity, and air composition corresponding to the simulation elements, and the human-machine environment engineering data is imported into the simulation sub-software module for simulation to obtain the simulation results, and the simulation results are imported into the evaluation sub-module for evaluation to generate the corresponding evaluation results, and the evaluation results are visualized.

[0038] The fluid mechanics simulation module is called and secondary developed by the fluid simulation software to achieve the purpose of geometric model sharing and data transmission. The fluid simulation results are directly applied to harmful gas evaluation, thermal comfort evaluation, etc. The evaluation methods such as vibration comfort evaluation, thermal comfort evaluation, and harmful gas evaluation are incorporated into the human-machine-environment evaluation module, and the parameters obtained by the above modules are input into the human-machine-environment evaluation module, and finally a comprehensive evaluation result can be obtained.

[0039] Specifically, the simulation submodule can perform simulation design in steps, and finally import the results into the result evaluation subsoftware module for evaluation.

[0040] Preferably, the description file / simulation result is in .doc file format.

[0041] Preferably, the simulation software includes a fluid simulation module and an analysis and evaluation module. Each module can be used independently or in combination, and the data is input into the evaluation module for analysis and evaluation.

[0042] Preferably, the simulation results are displayed to the user in a specified path folder on an interactive interface.

[0043] Preferably, the software system receives multiple instructions in the same time period, and can perform operations continuously through the workstation and use a queue mechanism for queue processing.

[0044] The human-machine environment comprehensive simulation design system proposed by the present invention adopts the simulation method in the above technical solution to perform simulation calculations.

[0045] Specifically, the human-machine environment comprehensive simulation design system includes: the comprehensive simulation software system and a client workstation platform on which the software system is installed.

[0046] The human-machine environment comprehensive simulation design system of the present invention mainly comprises a comprehensive simulation design system which can be built on multiple simulation platforms and integrates at least two kinds of professional simulation software.

[0047] In the development and design of the fluid mechanics simulation module, the three-dimensional fluid simulation analysis of the cabin is integrated and the visible and reachable effect display is developed. The module has an interface for calling the established typical model, designing the input environmental parameters, and performing three-dimensional flow field simulation. The software integrates three-dimensional fluid simulation analysis software, and saves the result report after the fluid mechanics analysis in the specified folder. Click the "Generate Fluid Result Report" button to generate a fluid calculation result report. According to the visible and reachable display range corresponding to the national military standards, different envelope effects corresponding to the visual and reachable display range of the virtual occupants inside the cabin are made and compiled into the software. Different viewing cones or envelope surfaces can be selected in the program interface to present different visible and reachable effects.

[0048] In the development and design of the human-machine environment evaluation module, thermal comfort analysis, vibration comfort evaluation, harmful gas evaluation and national standard query and retrieval functions are integrated into one, which can output a comprehensive evaluation index involving equipment vibration, ambient temperature, humidity, gas composition and other parameters. The module can quickly give timely, scientific and accurate evaluation.

[0049] The thermal comfort analysis function in the human-machine-environment evaluation module can realize thermal analysis and evaluation of the human body. This tool is implemented through Fortran language programming. The entire system framework is built under the framework of C++. It requires the use of hybrid programming technology and the integration of Fortran's thermal flow field calculation toolkit. According to the input parameters, the parameters of the human body are obtained by standard calculation. In order to more comprehensively evaluate the fatigue state of "people", the dynamic response system evaluation factors of the equipment carrier, especially the vibration acceleration in the vertical direction, will have an important impact on the fatigue state of the human body.

[0050] The vertical vibration acceleration at any time and any position output by the dynamic simulation module is transformed through fast Fourier transform, that is, the time domain curve of vibration acceleration is converted into a frequency curve. This calculation formula is incorporated into the software to analyze the vibration acceleration obtained by dynamic simulation, compare it with the vibration intensity and comfortable exposure time that the human body can withstand, and complete the vibration comfort evaluation function.

[0051] The harmful gas evaluation function in the human-machine-environment evaluation module places the post-processing results of the fluid mechanics simulation analysis software in a specified folder location and programs the harmful gas concentration limits allowed by the human body into the software. It supports the display of fluid calculation post-processing results and the report generation of fluid calculation results. It can display whether the results are acceptable on the interface based on the manually entered harmful gas concentration.

[0052] The national standard query and retrieval function in the human-machine-environment evaluation module incorporates relevant national military standards into the software, mainly including the human-machine engineering design criteria, fatigue vibration design criteria, and thermal efficiency design criteria standards for military equipment and facilities. For key items, a database system is established, corresponding to the items and content, which enables users to enter keywords and professional terms to query the relevant content of national military standards in real time and supports users to add new standards.

[0053] The comprehensive simulation design system provides users with an interactive interface for simulation analysis, analysis evaluation, and simulation model calling. Figure 1 As shown in the figure, the simulation model and simulation parameters are briefly described through simulation elements, and the software module is entered through the interactive interface.

[0054] The interactive interface of the comprehensive simulation design software provides the call of the fluid simulation module, provides the input design and simulation element window required in the simulation sub-software, and displays the simulation results accordingly. The human-machine environment evaluation module aggregated in the interactive interface is used to process the simulation model and simulation parameters to obtain the evaluation results of various factors of the human-machine environment.

[0055] The simulation elements include the various components that make up the simulation model, the connection relationship between the components, the position and physiological state of the human body, the environment corresponding to the simulation model, the equipment simulation parameters, and the relationship between the calling subsystems.

[0056] The human-machine-environment integrated simulation design system allows users to build simulation models and set related simulation parameters. In essence, it is a comprehensive software system that combines special equipment fluid simulation. The system integrates the simulation software functions required for human-machine-environment system engineering with a plug-in architecture, has all the design elements of simulation software, and there are many coupled simulation parameters and simulation elements in the simulation system. For example, the wheeled vehicle model can be used in fluid simulation and evaluation, that is, the vehicle body structure is a coupled simulation element. Users can build a simulation model of the entire human-machine-environment system in the integrated simulation design software, perform dynamic fluid mechanics simulation, realize simulation or measurement parameter evaluation, and interact with these complex and professional software operations in a friendly manner. The human-machine-environment integrated simulation system decouples and simplifies the functions of these diverse and complex simulation software, and then uniformly hands them over to the integrated simulation system workstation to perform specific simulation work.

[0057] The comprehensive simulation design software system will also process the simulation models and simulation parameters designed by the user, extract the simulation elements corresponding to the simulation models and simulation parameters, list the coupled simulation parameters between the simulation software, and use only one set of simulation elements to describe the mutually coupled parts between multiple simulation sub-softwares. The system will decouple the set of simulation elements according to the requirements of each simulation sub-software, and then allow the user to set the corresponding simulation parameters. In this way, the corresponding coupled simulation elements can be extracted without the need for repeated processing for different simulation sub-softwares. After the simulation is completed, it will be automatically stored in the description file.

[0058] The human-machine environment comprehensive simulation design software parses the description file and extracts simulation elements. Taking the human-machine environment analysis of the internal cabin of a tracked armored vehicle as an example, the extracted simulation elements include: tracked armored vehicle model, geometric characteristics of objects in the contact range of human sitting posture (such as seat height, backrest angle, pedal distance, etc.), human size, vehicle driving road conditions, cabin internal space size, air conditioning outlet position, fresh air supply volume, air supply temperature, air flow rate, harmful gas leakage point, human posture, etc. The simulation elements are classified, and each module classifies and extracts the corresponding simulation elements, directly calls the sub-software or calls the software API to build the simulation, and performs simulation to achieve the integration and friendly interaction of the simulation software required for the entire simulation system.

[0059] The final results obtained by each simulation software are stored in the specified path file directory in the sub-module-specific format and doc file format, and can also be displayed in charts as needed. Designers conduct multi-dimensional evaluation of the designed human-machine-environment system based on the corresponding simulation subsystem. If changes are required, repeat the above process on the workstation or running computer until satisfactory results are obtained.

[0060] Since the comprehensive simulation design software is installed on a computer, when multiple instructions are received in the same time period, the characteristics of the comprehensive simulation design software can be used to adopt a queue mechanism for queue processing, so that the workstation can perform calculations continuously and be used uninterruptedly.

[0061] The present invention integrates and collaboratively processes professional and complex human-machine environment system engineering simulation software through a comprehensive simulation system, thereby reducing the difficulty of comprehensive simulation of multiple factors such as man, machine and environment, and improving the efficiency of design simulation work. At the same time, because the simulation of multiple factors is coupled, full and reasonable use of workstation resources is made, thereby saving design time costs, as well as hardware costs and performance thresholds, simplifying operations and reducing design costs.

[0062] Through the software system of the present invention, it is possible to simulate the single-factor influence effects of human, machine and environmental factors, and it is also possible to simulate the mutual influence of various factors. It is possible to conduct comprehensive, integrated and professional inspection and optimization of ergonomics in the early process design stage, thereby solving the problem of time-consuming, labor-intensive and inefficient ergonomics verification in the later stage.

[0063] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.

[0064] Through the multi-factor coupling analysis method proposed in the present invention, the experience of special equipment human-machine environment design analysis is used to establish a simulation model, the design introduces a multi-factor comprehensive simulation method based on three-dimensional flow field, and compiles a comprehensive evaluation module of each factor, which can realize the simulation of the influence effects of various factors such as man, machine and environment, and the simulation of mutual influence. It can conduct comprehensive, integrated and professional analysis and optimization of human-machine engineering in the early stage of scheme design, thereby solving the problem that the existing foreign software has relatively single functions, is difficult to cover the analysis of the influence of temperature, humidity, air pressure, harmful gases, vibration, etc. on people in the operating environment, and is expensive, and avoids the problem that the later human-machine engineering rectification is time-consuming, labor-intensive and inefficient due to insufficient verification in the early stage of special equipment development.

[0065] The software system design method disclosed in the present invention is suitable for the multi-factor coupling design, analysis and evaluation of the human-machine environment of special equipment. It changes the current situation that commonly used software cannot analyze the impact of temperature, humidity, pressure, harmful gases, vibration, etc. on people in the operating environment. The comprehensive analysis factors are more comprehensive, the application range is wide, and quantitative evaluation indicators are obtained, which improves the efficiency of the equipment human-machine environment system design analysis.

[0066] The present invention has established a typical equipment human-machine environment multi-factor coupling analysis model through years of experience in special equipment human-machine environment design and analysis. On the basis of conventional human-machine environment engineering analysis, a multi-factor analysis method based on three-dimensional flow field is designed and introduced. Simulation elements are formed according to experience, and task priority is sorted to form different design analysis modules, so as to achieve the purpose of multi-factor coupling analysis of special equipment human-machine environment system, thereby realizing the quantitative design and analysis of equipment human, machine and environmental factors.
