November twenty fifth，The 5th China Simulation Technology Application Conference sponsored by China Industrial Cooperation Association was held in Beijing，The conference released the 2023 Excellent Case Award for Simulation Technology.，Sany Group Wins Three Awards，《Engineering equipment product digital twin platform R & D innovation project》Won the Excellent Innovation Award、《Fuel Cell System Simulation and Control Strategy Development》And《Optimization of Vibration Comfort of Electric Truck》Won the Excellent Application Award respectively，It is the only award-winning enterprise in the construction machinery industry.。

The theme of this conference is“Simulation Technology to Meet the Digital Age”，From domestic aerospace、Carrier equipment、Intelligent manufacturing、Civil Engineering、Enterprises in the fields of energy, chemical industry and industrial software、Colleges and universities、More than 500 leaders of scientific research institutes、Expert、Scientific and technological workers attended the meeting，It is an annual technical event in the field of simulation.。

Deputy General Manager of Sany Group、Ji Yongjun, President of Digital Twin Research Institute, was invited to attend the conference as Vice President of Simulation Technology Industry Branch.，Chair of the Steering Committee of the Conference and“Application of general industrial simulation technology”Chairman of the thematic sub-forum， Participation 、Host“Modeling, Simulation and Forward Design”High-end dialogue，And do the topic《Effects of Simulation on Product Innovation Research and Development from the Perspective of System Engineering》A keynote report。

He Yongjun interpreted the basic concepts and connotations of systems engineering.，It is pointed out that the model-based system engineering methodology is the mainstream methodology to guide the forward development of complex equipment.，Emphasize the use of modeling and simulation technology to develop product requirements in the early stages of product development/Function/Definition of performance、Decompose、Distribution and verification and validation，Identify and correct design defects in advance，Significantly reduce R & D cycles and costs。Construction of whole-machine performance prototype based on multidisciplinary system simulation technology，Integrated semi-physical simulation technology，Before the physical prototype is built, the virtual operation of the product can be realized in the digital space.，Conducting multi-option tradeoffs in the digital space、System/Selection and matching of parts and components、Overall Performance Analysis and Control Strategy Optimization、Potential failure prediction，Accelerate the pace of product innovation。

In recent years，Sany Group focuses on structural safety、Vibration noise、Many-body dynamics、Fluid、System、Electromagnetic compatibility constructs a complete digital simulation technology system.，Give full play to the enabling role of digital simulation technology in the process of product innovation and development，Significantly reduce physical verification cycles，Improve product quality and competitiveness，Boost“Globalization、Digitalization、Low carbonization”The strategy is achieved。
