VEHICLE DYNAMICS
“CAR MODELING THRU MULTI-BODY DYNAMICS USING MSC ADAMS”
Formula Student Car (SAE) competitions have come along way since they first started in 1980. One of the main categories for which these student teams are being evaluated on is the overall performance, reliability and endurance of their prototype.
In addition to the design, cost and manufacturing events, various sponsors of the competition provide awards for superior design accomplishments. For example, best use of E-85 ethanol fuel, innovative use of electronics, recyclability, crash worthiness, analytical approach to design, and overall dynamic performance are some of the awards available.
At the beginning of the competition, the vehicle is checked for rule compliance during the Technical Inspection. Its braking ability, rollover stability and noise levels are checked before the vehicle is allowed to compete in the dynamic events (Skidpad, Autocross, Acceleration, and Endurance).
MSC Adams is the most widely used multibody dynamics and motion analysis software in the world. With its help, engineers can study the dynamics of the moving parts, how loads and forces are distributed throughout the mechanical systems and seek to improve/optimize the performance of their products.
In MSC Adams, we can directly represent movement models without preparing any equation of motions which gives results in simpler manner.
Our goal in this hands-on course is to help students accelerate their prototype design and testing in order to properly and efficiently build a winning machine for these student competitions and represent their university proudly.
Having MSC Adams tool at your disposal to quickly turn around and validate concepts before building the prototypes will save time, money and sooo many frustrations along the way that we guarantee this investment of your time and effort will be worth it.

MSC ADAMS - MULTIBODY DYNAMICS
The Multibody Dynamics Simulation Solution
Adams helps engineers to study the dynamics of moving parts, and how loads and forces are distributed throughout mechanical systems.
Product manufacturers often struggle to understand true system performance until very late in the design process. Mechanical, electrical, and other subsystems are validated against their specific requirements within the systems engineering process, but full-system testing and validation comes late, leading to rework and design changes that are riskier and more costly than those made early on.
Simulate "Real World" Physics
As the world's most famous and widely used Multibody Dynamics (MBD) software, Adams improves engineering efficiency and reduces product development costs by enabling early system-level design validation. Engineers can evaluate and manage the complex interactions between disciplines including motion, structures, actuation, and controls to better optimize product designs for performance, safety, and comfort. Along with extensive analysis capabilities, Adams is optimized for large-scale problems, taking advantage of high performance computing environments.
Utilizing 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.
Most widely used mechanical system simulation software.
Adams stands for Automatic Dynamic Analysis of Mechanical Systems. It is a Multibody dynamics software that is used to study the dynamics of moving parts, and to determine how loads and forces are distributed throughout mechanical systems. With three decades of innovation and industry leadership, companies across industries choose Adams as their system dynamics solution.
Accurately predict loads for FEA
Dynamic loads are far more difficult to predict and understand compared to static loads, and this is especially true in systems with multiple moving parts, complex interactions and dynamic phenomena. Using Adams, engineers can calculate accurate dynamic loads applied through the system to any key component within it. Then, those loads can be used as inputs to component FEA models to get reliable results for stress analysis or fatigue analysis.
Represent flexibility efficiently in your system conveniently
Adams allows you to create flexible parts conveniently even in large motion systems that include complex interactions with other modeling elements. Engineers can either create a flexible components by importing MNF files from FEA software or generate flexible parts within the Adams environment using the Adams ViewFlex capability.
Design confidently with accurate mechanical model for controls system modeling
Nearly every mechanical system includes one or more control systems. By using Adams Controls, you can take your geometrically defined Adams models and easily incorporate them within block diagrams you have created with your preferred control system design software, such as EASY5, MATLAB Simulink or FMI supported tools.
Accelerate innovation by exploring multiple design concepts
Optimization analysis is important in every design process. Using Adams and Adams Insight, your design team can quickly understand the simulation that was run, investigate which factors have the greatest effect on each response, and easily make design changes and immediately understand how these changes will affect the overall performance of your design.
Real dynamics for vehicle design and testing
With the Adams Car products, engineering teams can quickly build and test functional virtual prototypes of complete vehicles and vehicle subsystems. Working in this environment, automotive engineering teams can exercise their vehicle designs under various road and test rig conditions, performing the same tests they normally run in a test lab or on a test track, but in a fraction of time.
