다물체 동역학 시뮬레이션

Adams는 세계적으로 가장 광범위하게 사용되고 있는 다물체 동역학 시뮬레이션 소프트웨어입니다. 설계자가 기계 시스템에서 하중이 어떻게 분배되는지 등과 같이 움직이는 구조물의 동적 특성을 분석할 수 있게 해줍니다.

기계적, 전기적, 또는 기타 서브시스템들은 시스템의 엔지니어링 프로세스 내에서 특정한 설계 사양에 따라 검증되지만, 전체 시스템 레벨에서의 시험과 검증의 결과는 늦게 나오기 때문에, 종종 설계 변경이나 재 제작을 필요로 하기도 합니다. 이러한 변경은 위험도와 비용을 증가시키게 됩니다. 초기 설계 단계에서 검증이 가능하다면 이러한 위험을 피할 수 있습니다.

Simulate "Real World" Physics

세계에서 가장 널리 이용되고있는 멀티 바디 역학 (MBD) 소프트웨어 인 Adams는 초기 설계 단계에 시스템 레벨의 설계 검증을 실현하고 엔지니어링 효율을 향상시켜 주며, 제품개발 비용을 절감할 수 있도록 돕습니다. Adams는 엔지니어들이 성능, 안전도, 안락감을 모두 만족할 수 있는 설계 최적화를 할 수 있도록 운동, 구조, 제어 등을 포함한 다분야 간의 복잡한 상호작용을 평가하고 관리할 수 있게 해줍니다. Adams는 광범위한 해석기능과 함께, 대규모 모델을 해석할 수 있도록 고성능 컴퓨팅 환경에 최적화 되어 있습니다.

Adams는 또한 다물체 동역학 해석 기술을 사용하여 FEA 솔루션 시간에 비해 훨씬 빨리 비선형 동적 해석을 수행합니다. Adams 시뮬레이션으로 하중과 힘을 계산하면 시스템의 전반적인 움직임과 작동환경 하에서의 변화하는 거동에 대한 FEA솔버의 해석 정확도가 향상됩니다.

Adams Control integration - Adams Control and Adams Mechatronics

Adams Mechatronics is a plug-in to Adams which can be used to easily incorporate control systems into mechanical models. Adams Mechatronics has been developed based on the Adams Control functionality and contains modeling elements which transfer information to/from the control system. For example, using Adams Mechatronics in Adams Car, you can quickly create assemblies of vehicle systems including control systems, and then analyze them to understand their performance and behavior.

• Add a sophisticated controls representation to your Adams model
• Connect your Adams model to block diagram models you've developed with control applications such as Easy5® or MATLAB®
• Experience flexibility in simulation styles to suit your problems' needs: simulate within Adams, within the controls software or co- simulation
• Access advanced pre-processing for Adams Controls
• Setup and couple a control system to a mechanical system
• Convert signal units automatically
• Connect transducer and actuator signals to the control systems easily
• Conveniently review and modify the control system input and output specifications
• Ideal for complex integrations

Adams Flexible Body Integration – Adams Flex and Adams Viewflex

Adams Flex provides the technology to correctly include a component’s flexibility even in presence of large overall motion and complex interaction with other modeling elements. Greater emphasis has been placed these days on high-speed, lightweight, precise mechanical systems. Often these systems will contain one or more structural components where deformation effects are paramount for design analyses and the rigid body assumption is no longer valid. Adams Flex allows importing finite element models from most major FEA software packages and is fully integrated with Adams package providing access to convenient modeling and powerful post-processing capabilities.

• Integrate FEA-based flexible bodies into your model
• Better represent structural compliance
• Predict loads and displacements with greater accuracy
• Examine the linear system modes of a flexible model
• Broad and convenient control over modal participation and damping

The ViewFlex module in Adams View enables users to transform a rigid part to an MNF-based flexible body using embedded finite element analysis where a meshing step and linear modes analysis will be performed.It is our new product module powered by MSC Nastran, allowing one to create flexible bodies without leaving Adams View and without reliance on 3rd party Finite Element Analysis software. Also, it’s a streamlined process with much higher efficiency than the way users have traditionally generated flexible bodies for Adams in the past.

• Create flexible bodies entirely within Adams View or Adams Car
• Reduce reliance on 3rd party FEA software using built in MSC Nastran technology
• Generate a flexible body from existing solid geometry, imported meshes or newly created extrusion geometry
• Obtain detailed control over mesh, modal analysis and flexible body attachment settings for an accurate representation of component flexibility

Adams Durability - Integrate with MSC Fatigue to do component life prediction

Durability testing is a critical aspect of product development and issues discovered late in the development cycle lead to project delays and budget overruns. Worse yet, “in service” failures lead to dissatisfied customers, safety issues, and warranty costs. Adams Durability allows engineers to assess stress, strain or life of components within mechanical systems to design products to last. Direct access to physical test data in industry-standard file formats enables engineers to use loads data captured during tests, and to easily correlate simulation and testing results.

• Shorten your development cycle, reducing costly durability testing
• Provide direct file input and output in RPC III and DAC formats to reduce disk space requirements and improve performance
• Perform modal stress recovery of flexible bodies within Adams
• Export loads to popular FEA software including MSC Nastran for detailed stress analysis
• Integrate with MSC Fatigue to do component life prediction

Adams Vibration - Create input and output channels for vibration analyses

With Adams Vibration, engineers replace physical tests on shaker devices with virtual prototypes. Noise, vibration, and harshness (NVH) are critical factors in the performance of many mechanical designs but designing for optimum NVH can be difficult. Adams Vibration allows engineers to easily study forced vibration of mechanical systems using frequency domain analysis.

• Analyze the forced response of a model in the frequency domain over different operating points
• Transfer your linearized model from Adams products to Adams Vibration completely and quickly
• Create input and output channels for vibration analyses
• Specify frequency domain input functions, such as swept sine amplitude/ frequency, power spectral density (PSD), and rotational imbalance
• Create frequency-based forces
• Solve for system modes over frequency range of interest
• Evaluate frequency response functions for magnitude and phase characteristics
• Animate forced response and individual mode response
• Tabulate system modal contributions to forced vibration response
• Tabulate contribution of model elements to kinetic, static, and dissipative energy distribution in system modes
• Specify direct kinematic inputs
• Plot Stress/Strain frequency response functions
