MSC软件公司,领先的多学科仿真解决方案,加速产品创新,发布了2014年版的Adams多体动力学仿真解决方案套件。Adams2014年引入了新的原生非线性部分建模和分析以及对Adams和MSC的Marc非线性有限元分析(FEA)解决方案之间的协同仿真功能。这些增强功能,MSC说,有效地解决设计和测试所造成的,缺乏系统的动力学和有限元分析领域之间的平滑整合的机械系统的挑战。Adams2014年又扩展了解决方案集的机械和汽车行业的版本,新的CAM模块Adams/Machinery及拓展车辆的建模和翻滚活动能力的Adams/Car。 

新Adams-Marc协同仿真功能使户能够执行Adams-Marc非线性有限元分析软件之间的协同仿真。此功能,介绍了MSC Adams使用的多体动力学模型,提高精度的工程师通过包括几何和材料非线性结构的行为,同时进行有限元分析工程师可以研究与现实的边界条件组件。协同仿真,MSC说,提供了“巨大的时间储蓄”运行非线性有限元分析,因为他们现在可以模拟Adams,而不是在有限元分析环境中的某些刚性运动部件的用户。 
 
新Adams/Machinery Cam Module模块提供了包括凸轮形状,从动运动,从动件布置,以及跟随器的几何形状的各种组合凸轮随动系统的易于使用的建模。 CAM模块,使得凸轮模型的创建速度更快,使设计变更提案的机制和凸轮轮廓更容易执行。 
 
在Adams/Car新车造型的改进包括稳定的事件,FTire动画和SmartDriver增强。Adams/Car现在提供了三种新的侧翻稳定性测试赛:路堤,螺旋和沙床。对于车辆的平顺性和稳定性研究,Adams/车用轮胎力要素2014的FTire接触力和轮胎的变形力,现在的Adams/ PostProcessor窗口内的动画。根据MSC,这种能力应为工程师提供了车辆行驶的事件更高保真度的分析和可视化,如轮胎滚过各种表面。 
 
Adams/Car 2014的SmartDriver增强应对车辆性能和操作的测试,以及需要进行建模和实质上模拟这些事件的继续演进。增强SmartDriver包括改进向后推动与支持开环事件的简单和自动的动力系统,额外的速度曲线样条插值的改进,不断的目标加速度和更平滑的油门和刹车的信号。 
Adams2014年亮相FE部分,对于非常大的变形,用例的具体考虑几何非线性新的Adams,本机造型对象。制定方案,介绍了MSC,是基于绝对节点,其改编坐标配方(ANCF)和几何精确梁配方(GEBF)。有了这些功能,工程师可以更准确地计算动态载荷的几何非线性部分的多体动力学系统中,根据MSC。 
 
FE部分提供了基本的2D选项以及一个3D梁配方的选择。后者MSC描绘成3D,完全几何非线性表示可用于梁状结构。新的FE加载功能提供了ADAMS / View的预处理器的创建,可视化和修改FE零件以及分布式负载的应用程序支持。 MSC报告说,在某些基准测试的情况下,建模时间减少的从8小时至30分钟。

MSC Software Corporation, the leader in multidiscipline simulation solutions that accelerate product innovation, has released the 2014 version of its Adams multibody dynamics simulation solution suite. Adams 2014 introduces new native nonlinear part modeling and analysis as well as a functionality for co-simulation between Adams and MSC’s Marc nonlinear finite element analysis (FEA) solution. These enhancements, says MSC, address the challenge of efficiently designing and testing mechanical systems that result from the lack of a smooth integration between system dynamics and FEA domains. Adams 2014 also extends the solution set’s machinery and automotive industry versions with a new Cam Module in Adams/Machinery and extended vehicle modeling and rollover events capabilities in Adams/Car.
 
Adams 2014 debuts FE Part, a new Adams-native modeling object for very large deformation use cases that specifically consider geometric nonlinearity. The formulation options, explains MSC, are based on its adaptations of the Absolute Nodal Coordinate Formulation (ANCF) and Geometrically Exact Beam Formulation (GEBF). With these capabilities, engineers can more accurately calculate dynamic loads for geometrically nonlinear parts within a multibody dynamic system, according to MSC.
 
FE Part offers a basic 2D option as well as a 3D Beam formulation option. The latter MSC portrays as a 3D, fully geometrically nonlinear representation useful for beam-like structures. A new FE Load feature provides the Adams/View pre-processor with support for the creation, visualization, and modification of FE Parts as well as the application of distributed loads. MSC reports that in some benchmark test cases, modeling time was reduced from 8 hours to 30 minutes.
 
The new Adams-Marc co-simulation capability enables users to perform co-simulation between Adams and Marc nonlinear FEA software. This functionality, explains MSC, lets engineers using Adams for multibody dynamics increase model accuracy by including geometrically and materially nonlinear structural behavior, while engineers performing FEA can study components with realistic boundary conditions. The co-simulation, says MSC, delivers “dramatic time savings” for users running nonlinear FE analyses because they can now simulate some rigid moving parts in Adams rather than in the FEA environment.
 
MSC says that the new Adams/Machinery Cam Module provides easy-to-use modeling of cam-follower systems that may comprise various combinations of cam shapes, follower motions, follower arrangements, and follower geometry. The Cam Module, the company adds, makes cam model creation much faster and makes design changes to mechanism motions and the cam profile easier to perform.
 
New vehicle modeling improvements in Adams/Car include stability events, FTire animations and SmartDriver enhancements. Adams/Car now provides three new rollover stability test events: Embankment, Corkscrew and Sand Bed. For tire force elements used in vehicle ride and stability studies, Adams/Car 2014’s FTire contact forces and tire deformation forces can now be animated within the Adams/PostProcessor. According to MSC, this capability should provide engineers with higher-fidelity analysis and visualization of vehicle ride events such as tires rolling over various surfaces.
 
MSC says that Adams/Car 2014’s SmartDriver enhancements address the continuing evolution of vehicle performance and handling tests and the need to model and simulate these events virtually. Enhancements to SmartDriver include improved backwards driving for open loop events with support for both simple and automatic powertrains, additional speed profile spline interpolation improvements, continuous target acceleration and smoother throttle and brake signals.
