The DLR EtherCAT library uses the open \u0000source EtherCAT library EtherLab to gather information \u0000about the connected bus slaves. Thereupon, the slave information is used in a code generation process to build \u0000native Modelica blocks providing the interfaces to their \u0000hardware counterparts. These blocks subsequently can be \u0000used to build real-time models, running on a Linux based \u0000real-time system and therefore controlling the hardware \u0000directly from the model.

The GCS is used to collect and compress low pressure gas streams for transmission into larger higherpressure lines. This system is simulated with ANSYS TwinBuilder. It includes models of the compressor, motor, bypass valve, and piping along with pressure sources for the low and high-pressure lines, which are controlled with measured or test data. To cycle and pressurize the GCS, a controller is implemented using an FMU from ANSYS SCADE. To interact with the system and monitor current operating conditions, a human machine interface (HMI) is also implemented using ANSYS SCADE as an FMU.","PeriodicalId":378465,"journal":{"name":"Proceedings of the 2nd Japanese Modelica Conference Tokyo, Japan, May 17-18, 2018","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127262700","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sekisue","doi":"10.3384/ECP1814886","DOIUrl":"https://doi.org/10.3384/ECP1814886","url":null,"abstract":"Because of the emerging market demand for higher power with higher efficiency for the power semiconductor devices, thermal design of the semiconductor package and its cooling method has become one of the key elements for the power supply systems in power electric design. Thus, many thermal designers now require the junction-to-case thermal Impedance ZθJC since it is one of the most important thermal characteristics of semiconductor devices and thus, in November 2010, the more reliable and sufficiently reproducible measurement method without a case temperature measurement has been standardized by JEDEC as JESD 51-14 (https://www.jedec.org/standardsdocuments/docs/jesd51-14-0) This paper shows the new feature in ANSYS simulation tool, ANSYS Electronics Desktop, which extracts ZθJC from JESD 51-14 compliant measurement data. The extracted ZθJC , or its cumulative expression of thermal resistance ∑ (Rthi) n i=1 and capacitance∑ (Cthi) n i=1 called “structure function”, is transformed to the Modelica thermal ladder network model. This Modelica model was simulated by ANSYS TwinBuilder, Multi-domain system simulator, and the junction temperature is reproduced by this simulation, that agreed well with the original measured temperature data. Further, ZθJC is split into two components, Junction-to-Die part(IC package DUT) and Heat-sink part(cold plate) in accordance with the guideline of Transient Dual Interface Measurement Procedure principle described in JESD 51-14. Then, ZθJC corresponding to IC package structure part is transformed to the VHDL-AMS model ( as IC Package thermal compact model ) while Heat-sink structure part is transformed to Modelica model(as testing fixture structure model) . Those models built by two wellknown physical model description languages were connected with the acausal (i.e., conservative) condition in ANSYS TwinBuilder and the thermal response of the combined model is evaluated. The result of the simulation matches to the full Junction-to-Heat-sink Modelica thermal ladder network model, that ensures Modelica and VHDL-AMS models can be connected in a single physical multi-domain system simulation environment in ANSYS TwinBuilder under the energy conservative principle, that might expand the potential applicability and the coverage for Modelica simulation for the broader application area.

Vehicle models used in these activities therefore need to be as accurate, and realistic, as possible. This paper will present the modelling and development of a pseudo-hydraulic power steering model, designed for usage in DiL applications. Specific focus during development has been towards the quantification and analysis of the torque feedback from the steering model to the simulator rig steering wheel, to produce as realistic a steering ‘feel’ as possible. Metrics derived from physical testing of vehicle steering systems have been deployed to analyze the torque feedback of the steering system. Subsequent assessment of the steering model and specific parameterization has been used to inform the model parameters utilized. Results quantifying the performance of the steering model during full vehicle testing using the Claytex VeSyMA platform are presented.","PeriodicalId":378465,"journal":{"name":"Proceedings of the 2nd Japanese Modelica Conference Tokyo, Japan, May 17-18, 2018","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124324239","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After that, more combination of exporting tools and importing tools of FMUs were tested for more realistic models. The success of the method was confirmed in the case of using FMI for Model Exchange (ME). Additionally the connection of FMUs generated from various modeling tools was tested using FMI for CoSimulation (CS) for a full-vehicle test model. Through the above-mentioned activities, we obtained much knowledge about utilizing FMI for practical model exchange in the industry. Finally the requests for future realization of FMI are described.","PeriodicalId":378465,"journal":{"name":"Proceedings of the 2nd Japanese Modelica Conference Tokyo, Japan, May 17-18, 2018","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126777658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
