“…Q L , the expansion failed, and X H would still be replaced by X R to compose a new simplex. The compression of the simplex was carried out through searching point X S by equation (9), and the objective function value of X S was Q S . If Q S \ Q L , the compression succeeded, and X H would be replaced by X S to compose a new simplex.…”

“…8 Therefore, there are large errors between the simulation and the actual situation. 9 On the other hand, various softwares supported by theories of different disciplines are adopted to establish models of various sub-systems in single-domain modeling and simulation, which will result in low efficiency of simulation and analysis deviation of system integration. Considering influences of each sub-system on the whole system of the punching press, the multi-domain modeling method, which assembles models from different sub-systems into an integral large model, 8,10 can greatly improve the simulation efficiency and avoid numerical solution problems induced by data exchange among various softwares.…”

The multi-domain modeling and simulation of the precision high-speed punching press was carried out using the software SimulationX in this article. The key technical problems of the multi-domain modeling, such as the establishment of the subsystems of mechanics with accurate structures and dimensions, improvement of modeling accuracy and simulation efficiency by dividing and dealing with components in group and import of the displacement-depended stamping forces on the stamping dies, have been resolved to establish the integral multi-domain model, which contains subsystems of mechanics, hydraulic and servo driven of the complete punching press. Vibration quantity of the punching press was predicted through simulation, and validity of the multi-domain model was confirmed by experimental measurement. The vibration reduction in the punching press based on the topology optimization of the slider and design of rotational speed variation curve of the servo motor were investigated. The results show that through topology optimization, the mass of the slider could be decreased under the premise of guaranteeing the structural strength, by which the vibration quantity of the punching press can be decreased; rotational speed of the servo motor could be decreased during the stamping period by designing the rotational speed variation curve, which leads to a decrease in acceleration and vibration of the slider during that period, with which the forming precision can be guaranteed.

“…Recently, there is an emerging research trend for multi-domain simulation, where physical factors in more than one system such as electrical, chemical and mechanical are jointly simulated [60]. In the domain of digital processor design, Cacti [136] estimates power, area and timing specifically for memory system.…”

A Language and Platform Independent Co-Simulation Framework Based on the Functional Mock-Up Interface

The main goal of the Functional Mock-up Interface (FMI) standard is to allow the sharing of simulation models across tools. To accomplish this, FMI relies on a combination of XML-files and compiled C-code packaged in a zip archive. This archive is called a Functional Mock-up Unit (FMU). In theory, an FMU can support multiple platforms, but not necessarily in practice. Furthermore, software libraries for interacting with FMUs may not be available in a particular language or platform. Another issue is related to the protection of intellectual property (IP). While an FMU is free to only provide the C-code in its binary form, other resources within the FMU may be unprotected. Distributing models in binary form also opens up the possibility that they may contain malicious code. In order to meet these challenges, this paper presents an open-source co-simulation framework based on FMI, which is language and platform independent thanks to the use of well-established remote procedure call (RPC) technologies. One or more FMUs are wrapped inside a server program supporting one or more language independent RPC systems over various network protocols. Together, they allow cross-platform invocation of FMUs from multiple, including previously unsupported, languages. The client-server architecture allows the effective protection of IP while also providing a means of protecting users from malicious code.
