7 [. K' i2 N0 W& Z0 d Overview This chapter contains the basics of the ADAMS/Chassis analysis environment and introduces the tutorials found in later chapters: About ADAMS/Chassis, 4 What You Will Learn, 5 Starting ADAMS/Chassis, 6 Familiarizing Yourself with ADAMS/Chassis, 8 Getting Started Using ADAMS/Chassis Introducing ADAMS/Chassis About ADAMS/Chassis ADAMS/Chassis provides a complete analysis environment for automotive MSC.ADAMS analysis. It does this by providing standard model types, two analysis types, and post-processing. You run ADAMS/Chassis in conjunction with ADAMS/Solver and ADAMS/PostProcessor. ADAMS/Chassis comes with many standard suspensions such as: Short-long arm MacPherson Hotchkiss 4 Link Quadralink Using ADAMS/Chassis, you can perform the following types of analyses, also referred to as events: ■ Half-vehicle analyses - During half-vehicle analyses you examine the behavior of suspensions. Half-vehicle analyses include: ❖Ride motion ❖Roll motion ❖ Steering" S8 ` C) E+ o, t1 N/ N8 {

Full-vehicle analyses - During full-vehicle analyses you examine the behavior of complete vehicles. Full-vehicle analyses include: ❖Step steer ❖Frequency response ❖Oncenter handling❖Constant radius Getting Started Using ADAMS/Chassis Introducing ADAMS/Chassis The majority of these standard events come with standard postprocessing; that is, plots or reports or both. ADAMS/Chassis also helps you with the virtual prototyping process by: ... Substituting rigid bodies with flexible bodies through ADAMS/ChassisMakeflex and ADAMS/Flex. Modeling complex leaf spring interactions with ADAMS/Chassis Makeleaf. Using ADAMS/Driver to learn how to best drive a course. What You Will Learn This guide contains five tutorials that step you thro UGh the traditional iterative analysis process, which is one of the many ways you can solve complex system problems using ADAMS/Chassis. The first three tutorials build on each other and assume that you work through them in sequence. The last two tutorials in the final chapter are independent of the other tutorials. However, they still assume that you have learned the ADAMS/Chassis interface by running through the other tutorials. In the tutorials, you will perform the following tasks: Build half-suspension, full-vehicle models, and leaf-spring models. Analyze models in different virtual tests. Review analyses using animation, plotting, and reports. Modify models and review the effects of your design changes. Iterate your design to achieve performance targets for your model. Getting Started Using ADAMS/Chassis Introducing ADAMS/Chassis Starting ADAMS/Chassis In this section you learn how to start ADAMS/Chassis in the UNIX and the Windows environment. You must run ADAMS/Chassis in a directory to which you have write permissions. The example models in the installation are always write protected. You must use Database Utilities to copy the example model from the installation directory to your working directory. Database utilities automatically changes the permission for you so that the files can be overwritten. To start ADAMS/Chassis in the UNIX environment: 1At the command prompt, enter the command to start the MSC.ADAMS Toolbar,and then select Enter. The standard command that MSC.Software provides isadamsx, where x is the version number, for example adams05r2. The MSC.ADAMS Toolbar appears. 2Select the ADAMS/Chassis tool 3Select OK.The ADAMS/Chassis main window appears as shown in Figure 1 on page 7. To start ADAMS/Chassis in the Windows environment: 1From the Start menu, point to Programs, point to MSC.Software, point toMSC.ADAMS 2005r2, point to AChassis, and then select ADAMS - Chassis. 2Select OK.The ADAMS/Chassis window appears as shown in Figure 1 on page 7.

Treeview Property Editor Getting Started Using ADAMS/Chassis Introducing ADAMS/Chassis Familiarizing Yourself with ADAMS/Chassis Here you will learn about the ADAMS/Chassis work modes and toolbars. ADAMS/Chassis Work Modes ADAMS/Chassis is divided into four work modes: Build Test Review Improve Build The Build mode allows you to edit model data and change system configuration. You can also work on multiple models at once. The Build mode is the default for starting ADAMS/Chassis. Test The Test mode allows you to build and run your model. Review The Review mode allows you to visualize analysis results using ADAMS/PostProcessor. You can postprocess the output of standard ADAMS/Chassis events. Postprocessing has two formats: reports and plots. A majory of standard ADAMS/Chassis events have either a report, a plot, or both. You can also create an animation of your event. Improve The Improve mode allows you to refine models with ADAMS/Insight. Here you can use the features from ADAMS/Insight to create sophisticated experiments for measuring the performance of your model. It also provides a collection of statistical tools for analyzing the results of your experiments so that you can better understand how to refine and improve your model. Getting Started Using ADAMS/Chassis Introducing ADAMS/Chassis Learning About the Toolbars The toolbars in ADAMS/Chassis change according to the work mode. Below is the basic toolbar that is available in all work modes. Figure 2. ADAMS/Chassis Basic Toolbar
