After 20 years navigating in virtual worlds, we finally appear in print. This book will introduce you in your native language to the world of holistic system modeling and simulation – a software application area that has become increasingly popular amongst engineering professionals world‐wide. ITI was found in 1990; its headquarters is situated in Dresden/Germany. In the past two decades we have become one of the world’s leading companies in the field of dynamic modeling, simulation and analysis of technical systems. Our product SimulationX is a software platform that is used in more than 15 industrial branches and has long proven its excellent performance in over 300 different applications. The number of customers using SimulationX around to globe to develop innovative technical goods such as plants, machines and devices with high power density in an energy‐efficient, optimal and quick way exceeds 600. In addition to developing high‐performance multi‐domain software we provide specialized engineering know‐how at highest level. For more than five years ITI has been investing in China. The importance of our Chinese customers has been steadily growing ever since. Thanks to the dedication and commitment of SimulationX users and partners across all regions in China this market has become one of the most important ones for our company. Thus, it is with great pleasure that we provide our Chinese SimulationX users with best possible local support. Together with the SimulationX Training Center in Beijing (Beihang University) it has been possible to live up to the high expectations of both, the users and ourselves. This being the case, I want to unreservedly thank Prof. Xiangyang Xu, Director of the SimulationX Training Center in Beijing, and Dr. Wenyong Li, ITI’s China manager, for their continuous support. Thanks to their effort and the one of their teams this publication was finally brought into being. In 1995, we had the vision of creating a Chinese‐German cooperation to build up a SimulationX competence center for the local support, training and technical consulting. Today, this vision is completed and, moreover, we have established a true friendship. This fruitful partnership has become a significant, sustainable bridge between ITI’s engineering and development team and the Chinese SimulationX community. The book is dedicated to anyone using modern calculation software to speed‐up the development of mechatronics systems. It comprises the basics of system simulation and SimulationX from the technology and user interfaces over methods and computation through to analysis. Also, a various practically‐oriented engineering applications are presented. Yet, this can only be small samples from a wide range of plant modeling and simulation possibilities. Please do not hesitate to contact us whenever you have any questions or need assistance in one of your projects. Again, thank you very much indeed for your interest in this book. Enjoy reading and working with SimulationX! Jens O. Schindler ITI Executive Director 引言2008的金融危机再一次证明技术创新是企业应对金融危机的最有效手段。技术创新对于我国制造业意味着企业研发信息化，目前以CAD为主导的产品研发信息化造成了重几何结构、轻性能设计；强信息集成，弱模型集成；缺系统综合创新设计能力，造成制造企业在产品研发方面核心能力的缺失。尤其在复杂产品研发过程中，以产品数据管理为核心的PDM/PLM系统强调产品设计数据管理，而对CAE协同分析仿真过程的支撑相对较弱，不能有效支撑复杂产品系统设计仿真过程中数据、模型、知识、资源及过程的统一管理。 复杂高性能机电系统对产品设计在理论、方法和技术手段三个层面提出了新的挑战。对象的本构多域性及复杂性用现有的单领域工具无法解决，这就需要一种以知识可重用、系统可重构为模式的复杂产品建模、分析、仿真、优化一体化的设计技术，即机、电、液、控、热一体化设计的多学科设计技术，欧美于1996年开始针对性地开展了多领域物理建模与分析，并提出了具有普适性、可拓展的多领域物理建模语言modelica,并成立了开放的国际Modelica合作组织（）,旨在为新一代复杂机电系统设计方法与技术提供模型知识的表达、计算的规范，Modelica被认为是IT技术与工业领域的具有里程碑意义的基础创新，近年来该技术在一批重要行业的典型产品的开发中得到成功应用，得到国际研究机构及工业界的认同，发展迅猛，2006年6月法国达索系统宣布以Modelica为技术标准实施“knowledge inside”，国外许多重要企业及研究机构已宣布以Modelica为模型表达标准，如欧共体组织ITEA2项目。目前Modelica 已成熟的应用在于航空航天，汽车和工程机械等领域，该类仿真软件的代表为德国ITI公司的SimulationX。 德国ITI有限公司开发的SimulationX一直领跑在工程化系统工程建模和仿真技术的最前沿，作为优秀的Modelica商用系统标准平台，每年和世界著名厂商和研究机构都成功地完成数十个大型工业项目，这些项目的完成为公司赢得了广泛的声誉，积累了丰富的专业知识和行业应用经验，也使软件产品获得了世界最优秀传动仿真的软件的称号。在2007年进入中国市场后得到了中国高校和企业的迅速的认可和广泛好评。为了回馈中国用户，ITI有限公司联合ITI‐SimulationX北航技术培训中心开始编著SimulationX的中文使用丛书。 本书为SimulationX工程系统的多学科复杂建模和分析的第一册，从SimulationX的基础开始，通过一步一步的图文并茂的阐述，使用户最后能利用SimulationX 来完成各种工程系统的多学科复杂建模和分析，解决具体工程问题。既有理论说明，又有案例分析; 它既是SimulationX的初级用户的良师，又是SimulationX的高级用户的益友，同时也可作为广大科技工作者和工程技术人员的重要参考书。今后还将陆续推出更多关于基于Modelica的二次开发及各个工程领域建模高级应用的系列丛书，以帮助中国用户同步掌握世界先进的基于Modelica的多学科复杂建模和分析的仿真技术，支持读者进行原创设计，为中国创造助力。在此感谢ITI有限公司工程技术人员和徐向阳教授领导的ITI‐SimulationX北航技术中心的辛勤工作。 黎文勇德国IT
