Collaborative R&D Environment combines design model management, R&D technology management, R&D process management, multidisciplinary optimization, multiphysics simulation, simulation data management and intellectual asset management, and makes full use of enterprise distributed hardware resources and grid computing resources. To support any R&D activities of the company.
The rapid development of modern enterprise R&D technology has made CAD/CAE software flourish. This has brought a lot of choices for enterprises, but it also brings heterogeneous problems. In their efforts to solve these heterogeneous problems, enterprises have discovered a major feature of modern R&D technology: CAD technology is converging, while CAE technology is seeking differences. Design tools can be unified by selecting the same CAD system across the enterprise. But for simulation, no simulation system can be used to protect the world, and each tool has its irreplaceable value. Faced with this situation, while maintaining the core technology diversity of enterprises, the call for establishing a collaborative R&D environment is getting higher and higher.
The so-called "cooperative R&D environment" refers to the integration of all R&D tools according to the characteristics of modern enterprise R&D activities to form a network-based, distributed enterprise-level collaborative R&D platform. The platform integrates design model management, R&D technology management, R&D process management, multidisciplinary optimization, multiphysics simulation, simulation data management and intellectual asset management, and makes full use of enterprise distributed hardware resources and grid computing resources to support Any research and development activities of the enterprise.
PERA was born on the basis of J2EE-based infrastructure, integrating the various R&D tools currently used by enterprises through the integration of three sub-platforms. Figure 1 reflects the integrated architecture of PERA. This is a three-tier architecture based on the network, including the base layer, sub-platform layer and tool layer.
Figure 1 PERA's integrated architecture
J2EE base layer
PERA adopts the J2EE (Java To Enterprise Edition) standard to ensure that the platform is a collaborative development platform between enterprises or enterprises. Through two modes (main model sharing and associated master model), alliance-based cross-domain collaboration is achieved for enterprise-level, enterprise-to-enterprise, and global communication, collaboration, and collaborative development. PERA uses international advanced database technologies (such as IBM DB2, Oracle, SQL SERVER, MYSQL, MS ACCESS) and grid computing technology to ensure that this platform stays ahead for many years. PERA uses a comprehensive security system, such as X509 CA authentication and digital signature, encrypted storage of files and key data, and HTTPS encrypted transmission to ensure the security of data access and sharing at the enterprise level.
PERA provides a highly flexible infrastructure. On this infrastructure, engineering tools such as design, simulation, optimization, cost and weight estimation can be used as requesters or providers of distributed services, using Web technology to cross-distribute on different operating platforms. PERA's integrated R&D tools for modern companies include mechanical design, electronic design, physical field analysis, multi-body dynamics analysis, circuit simulation, hydraulic simulation, control simulation, cost estimation, weight estimation, and multidisciplinary optimization.
In addition to being able to integrate enterprise PDM systems, PERA has two important sub-platforms for technology integration and process integration. They are Workbench and Fiper.
R&D technology integration sub-platform - Workbench has established an integrated platform for enterprise R&D technology (Figure 2), integrates all the world's mainstream R&D technologies, and maintains a multi-disciplinary technology core diversification while establishing a unified R&D environment. In this environment, the staff always faces the same interface without having to switch frequently between various program interfaces.
Figure 2 Workbench establishes a unified simulation environment
R&D process integration sub-platform â€“ Fiper has established a collaborative platform for enterprise R&D processes (Figure 3). In this sub-platform, the main process, the auxiliary process of product development and the data transfer relationship between the processes can be defined, designed and coordinated, and the product's various indicators can be completely studied.
Figure 3 Fiper working principle
Multidisciplinary optimization is a direct result of process integration. PERA uses iSIGHT as a multidisciplinary optimization tool, and Fiper provides a dedicated plugin for iSIGHT.
Simulation data management
Under the successful implementation of PDM, enterprises can manage the design data of the enterprise well, but the particularity of the simulation data requires special mode management. PERA's simulation data management system EDM (Engineering Data Management) uses BOE (Bill Of Engineering) to manage simulation data. BOE integrates all simulation data from the same R&D project and embodies the logical relationship between simulation behavior and data.
R&D platform implementation
Figure 4 PERA common application architecture
Figure 4 shows the common application architecture of PERA. Like PDM, PERA is a system that needs to be implemented. The implementation personnel need to implement the customization according to the R&D process and simulation requirements of the enterprise, and form a simulation work platform that conforms to the R&D process of the enterprise. However, the implementation of the collaborative R&D platform is more difficult than the PDM-only platform for data management. The implementation team not only has excellent IT knowledge, but also needs to be familiar with various R&D tools, while also understanding and helping users optimize their R&D processes. . To this end, Anshi Asia Pacific has deployed a high-level professional implementation team. This team consists of foreign platform implementation consultants and developers with many years of platform implementation experience, and hired experts from Boeing and other companies to help companies and implementation teams optimize the R&D process. They have successfully implemented a number of platform projects at home and abroad to ensure the successful implementation of the collaborative R&D platform of Chinese companies.
