6 Understand ADAMS product nomenclature and terminology. Understand Basic modeling principles and extend your proficiency by creating progressively more complex models. Use the crawl-walk-run approach to virtual prototyping. Debug your models for the most common modeling challenges (for example, redundant constraints, zero masses, and so on). Use and be informed about all methods of ADAMS product support. Use the product documentation of guideThis Guide is organized into modules that get progressively more complex. Each module focuses on solving an engineering-based problem and covers mechanical system Simulation (MSS) concepts that will help you use ADAMS most optimally. The earlier workshops provide you with more step-by-step procedures and guidance, while the later ones provide you with module is divided into the following sections: 1 Problem statement2 Concepts3 Workshop4 Module review Cover the organization of Guide section in detail, and reinforce this layout as you go over each to Basic ADAMS TrainingGetting Help at Your Job SiteOnline guides Access help on help from Help menu of any ADAMS product Help tool on the Documentation Road Mapknowledge base Go to a quick tour, go to email-based users group Go to services Go to Technical support To find your support center, go to read the Service Level Agreement, go to Technical Support: Discuss what is available through your local office or headquarters, if appropriate.

It does not cover Optimize or Mechanism15 Problem statementUnderstand the virtual prototyping process by improving the design of the stamping mechanism shown next:Model description This model represents a mechanism for stamping parcels that are moving along a conveyor belt. During the work cycle, the stamp does not contact the parcels that it is supposed to label. To fix this design flaw, modify the length of the control Review problem statement. Objective of the exercise is to demonstrate the typical ADAMS process. We have built a model, parameterized it, and automated it. Students must use this customized version of ADAMS to make changes to the model, iterate, and optimize it. There is a file named in that directory that tells ADAMS /View what to do to build the model and put all the automation in place. Before starting, ask if there are any 1 Stamping Mechanism16 Stamping MechanismWorkshop 1 Stamping the workshopYour first step will be to start ADAMS /View from the directory exercise_dir/mod_01_stamper.

9 When you start ADAMS /View from that directory, it automatically builds the model stamp and a fully customized version of ADAMS /View. There are separate instructions for starting ADAMS /View in UNIX and Windows NT. Follow the set of instructions below depending on the platform you are using. If you are using UNIX, to start ADAMS /View:1At the command prompt, enter the command to start the ADAMS Toolbar, and then press Enter. The standard command that MDI provides is adamsx, where x is the version number, for example adams11, which represents ADAMS the ADAMS toolbar, right-click the ADAMS /View tool .3 Select Change Settings for Change Settings for A/View dialog box Working the Working directory text box, and then select Select a Select a Directory dialog box appears. 6 Select the directory mod_01_stamper (exercise_dir/mod_01_stamper). 7 Select OK. 8 From the Change Settings for A/View dialog box, select the ADAMS toolbar, select the ADAMS /View tool.

10 ADAMS /View starts and automatically imports the commands to build: Model named stamp. Fully customized version of importing the commands, an Information window appears. 10 Read the information describing the model, and then, in the upper right corner, select Close. Stamping Mechanism17 Workshop 1 Stamping you are using Windows NT, to start ADAMS /View:1 From the Start menu, point to Programs, point to ADAMS , point to AView, and then select ADAMS - starts and the Welcome dialog box the Welcome dialog box, select Import a file. 3 Click the file folder. The Find Directory dialog box and select the directory mod_01_stamper (exercise_dir/mod_01_stamper). 5 Select OK. The File Import dialog box File Type to ADAMS /View command file (*.cmd).7 Right-click the File to read text box, and then select Browse. The Select File dialog box appears. 8 Select the file, , and then select Open. 9 Select imports the commands to build: Model named stamp.
