《多体动力学和运动分析软件》MSC Adams 2012

Adams是目前世界上应用最广泛的多体动力学和运动分析软件人人素材。Adams帮助工程师研究运动部件的力量变化，在整个机械系统内，荷载和力量是如何分配的，并改善和优化其产品的性能。

现在，传统的“构建和测试”的设计方法太昂贵，太耗时，有时甚至是不可能成功。基于CAD的工具可以帮助评估部件之间的干扰，基本运动，但忽略了复杂机械系统的基于物理学的力量变化。有限元分析是研究直线振动和瞬态动力学的最优选择，但采用该种方法分析大型旋转和其他高度非线性机械系统全面运动的效率太低。
Adams多体动力学软件使工程师能够轻松地创建和测试机械系统的仿真原型，所占用的时间和花费的费用仅仅占了物理创建和测试所需花费的一小部分。与大多数内嵌CAD工具不同的是，Adams通过同时采用运动学，净力学，以及准净力学方程求解的方法，结合了实际物理。利用多体动力学解决方案的技术，Adams同时也运行非线性动力学，所需要的时间仅仅是有限元分析解决方案所需时间的一小部分。通过更好地评估它们在整个运动和经营环境中如何变化，提高有限元分析的准确性，Adams模拟计算的荷载和力量提高了有限元分析的准确性。

全新的用户界面
Adams 2012 用户界面提供了一种新的带状格式和直观布局。新的带状风格提供了改进的标签，从而使建模更轻松，更便于使用。工程师会发现原主工具箱和建模菜单项，将以一系列的选项卡方式呈现在主菜单条和状态工具条中，如实体建模，仿真和后处理等功能。
同时，Adams 2012还实现了一款新的前处理模型浏览器，即提供一种改进方法，用于在Adams/View内实现模型导航。这对于理解从同事或者商业合作伙伴那里新获取的模型结构关系特别有用。工程师将体验到改进的模型导航，特别是对于复杂模型，右键点击即可方便浏览非图形实体，动态搜索和可保存过滤器，以及改进的可视化和模型控制。

自动柔性体生成
2012版Adams 引入了新的Adams/ViewFlex模块，使用户在无需脱离Adams环境或者依赖于外部有限元建模(FEM)或有限元分析(FEA)软件的情况下，即可创建柔性体。该功能技术支持来自嵌入式MSC Nastran，整体在Adams后台运行实现。这样可以提高设计效率，使高保真建模变得更容易。
提高求解器计算速度和稳定性
改进后的Adams 2012 C++ 求解器目前是所有Adams产品，包括Adams/View和Adams/Car的默认求解器。Adams C++ 求解器提供了FORTRAN求解器中所不具备的建模与仿真能力，如非线性BEAM和FIELD，柔性体接触，间隙测量，精确线性化算法，Adams/Controls系统导入选项中的对分法，支持延迟微分方程，以及并行处理等功能。

汽车模块功能增强
Adams 2012引进了新的Adams/Car轮胎和道路强化技术，可以进行具有较高保真度的道路模拟试验。新的轮胎三维包络接触模型可以捕捉到越过小障碍物时更加真实的轮胎力。道路可视化目前处理速度更快，更好地提升与模拟代码的一致性，从而提高用户理解车辆运动性能和改进视觉效果的能力。
Adams/Car增加了新的车辆仿真事件，包括保持直线运动，不同附着系数路面上的直线制动，以及车辆静态设置，其中包括四个车轮的独立负重，束角和外倾角定位，以及车身高度调整。这些新功能为用户提供了较佳的仿真事件选择，提高了分析效率，且易于使用。在Adams/Chassis中，新的柔性体生成功能目前可以与任何支持柔性体的部件配合使用，相比之下，以前提供的车身连接点功能仅与车身和车架部分配合使用。这样就可以提高效率，使高保真建模变得更容易。

About MSC Software.

MSC Software is one of the ten original software companies and the worldwide leader in multidiscipline simulation. As a trusted partner, MSC Software helps companies improve quality, save time and reduce costs associated with design and test of manufactured products. Academic institutions, researchers, and students employ MSC technology to expand individual knowledge as well as expand the horizon of simulation.

MSC Software's engineering simulation technology is used by leading manufacturers for linear and nonlinear finite element analysis (FEA), acoustics, CFD, multi-physics, optimization, fatigue and durability, multi-body dynamics, and control systems simulation. The company's products accurately and reliably predict how products will behave in the real world to help engineers design more innovative products - quickly and cost effectively.

Overview

Traditional "build and test" design methods are expensive, time consuming, and impossible to do sometimes. CAD-based tools help to evaluate things like interference between parts, and basic kinematic motion, but neglect the true physics-based dynamics of complex mechanical systems. FEA is suited for studying linear vibration and transient dynamics, but inefficient at analyzing large rotations and other highly nonlinear motion of full mechanical systems.

Adams multibody dynamics software enables engineers to easily create and test virtual prototypes of mechanical systems in a fraction of the time and cost required for physical build and test. Unlike most CAD embedded tools, Adams incorporates real physics by simultaneously solving equations for kinematics, statics, quasi-statics, and dynamics.

Utilizing rr-sc.com multibody dynamics solution technology, Adams runs nonlinear dynamics in a fraction of the time required by FEA solutions. Loads and forces computed by Adams simulations improve the accuracy of FEA by providing better assessment of how they vary throughout a full range of motion and operating environments.

Optional modules available with Adams allow users to integrate mechanical components, pneumatics, hydraulics, electronics, and control systems technologies to build and test virtual prototypes renrensucai.com that accurately account for the interactions between these subsystems.
