在二十一世纪的第一个十年,多体动力学技术的发展已从“多体仿真”阶段迈入“机-控系统优化”的新纪元。RecurDyn承继了自70年代以来所有主要的多体动力学相关技术,加上特有的递归算法(Recursive Formulation)、完全柔性体算法(MFBD)、解析接触算法(Analysis Contact)、实体接触算法(solid contact)、控制集成技术(Colink)、自动设计优化技术(AutoDesign)、以及创建客户自主产品的数字化开发平台所需的二次开发工具包(PNet),提供了 “仿真驱动的产品数字化开发”所需要的技术。RecurDyn已是原创开发以机-电-控结合的现代产品所不可或缺的关键工具。
RecurDyn 具有令人震撼的求解速度与稳定性,凭借其特有MFBD多柔体动力学分析技术的优势,经过十年的不懈努力建立了不可动摇的全球市场地位,许多国际知名大企业已改用RecurDyn进行机构方面的产品研发。
鉴于RecurDyn 的强大功能,软件广泛应用航空、航天、兵器工业、军事车辆、军事装备、工程机械、传送机械、电器/电子设备、娱乐设备、汽车制造、发动机行业、铁道、船舶机械及其它通用机械等行业。

RecurDyn的优势以及多体系统的发展趋势
大型模型的运算
除了原有的针对大型多刚体模型所提供的递归算法(Recursive Formulation),RecurDyn也增加了针对大型有限元多柔体(MFBD)模型的SMP并行求解;这两种方法对提高大型模型的计算效率起了重要的作用。
滑动和碰撞接触
除了原有面接触算法(surface contact algorithms)的改良外,RecurDyn也提供了解析接触算法(Analysis Contact),稳定性更高的实体接触算法(solid contact algorithms),以及支持柔性体的接触算法;这些算法大幅提高了接触计算的速度、稳定性和精确性。
运动中的柔性体
除了原有以运动中的振动为仿真目的的RFLEX模态法柔性体算法,RecurDyn也开发了以运动中的接触、大变形、和其它非线性为仿真目的的MFBD有限元柔性体算法;计算精度因此得到了较大的提升。
控制-机构集成
除了原有的与MATLIB/Simulink联合仿真的功能外,RecurDyn的研发部门直接将控制系统的建模界面和算法集成到RecurDyn中,RecurDyn的求解器已可以实现机构和控制两种算法的耦合求解。机构与控制在RecurDyn中融合成了一个单一的数字化系统。
系统的设计与优化
为了达到以仿真驱动设计的目的,首先RecurDyn针对不同的产业,推出了各种专业建模工具包;包括发动机的各个子系统、机床、履带、进纸机构、链、带、滑轮、齿轮、轴承、弹簧等都有专用的工具包。这些工具包的出现大幅缩短了工程师建立(并修改)数字化仿真系统所需的时间。接着RecurDyn提供了全面的参数化几何建模和优化功能,帮助工程师以数字方法寻找更优的设计方案。更重要的是RecurDyn推出了ProcessNet二次开发工具包;客户可以依据各自的产品特性和设计需求,开发出专用的参数化系统和设计优化的开发平台。仿真本身已不再是目的,设计的优化才是多体系统仿真的真正目的。
FunctionBay RecurDyn V8R2 SP1.1 | 3.4 Gb
FunctionBay, Inc., a professional CAE company and provides MultiBody Dynamics (MBD) software, announced the release of RecurDyn V8R2, is CAE software that is focused on Multi-Body Dynamics (MBD) while also offering multi-physics solutions.
The RecurDyn technology has superior calculation efficiency because it is based on a recursive formulation. The core is Multi-Flexible Body Dynamics (MFBD) that combines a multibody dynamics solver and a nonlinear finite element method solver at the integrator level. RecurDyn supports other multidisciplinary CAE technologies such as control system modeling and nonlinear system-level optimization. RecurDyn provides the efficiency gains of process automation through a wide variety of application toolkits. Users can create their own custom applications using the bundled ProcessNet environment.
RecurDyn provides a unique MFBD analysis capability that combines MBD with Finite Element Analysis (FEA) methods in order to simulate moving assemblies of rigid and flexible bodies. The user can determine the detailed dynamic stress and stain within the context of a system-level analysis, including the time-varying inertial forces.
There are two types of flexible bodies that are supported with MFBD. The first type of flexible body (RFlex) is a simplified representation that is based on modal data generated by external FEA software. FFlex flexible bodies are based upon an FE mesh, where all nodal DOFs are retained.
RecurDyn V8R2 is more powerful and convenient to use than ever. It contains more than 100 new features and improvements, such as optimizations to the user experience, improved convenience in MFBD (Multi-Flexible Body Dynamics) model, post-processing improvements, increased library of material properties, and enhanced solver performance.
RecurDyn V8R2 improves the user experience of transforming an MBD model into an MFBD model, strengthens MFBD analysis, and improves post processing. And it also contains enhancements to its customized Toolkit for major industries to improve user convenience and engineering capabilities.
