Using the AMESim MATLAB/Simulink Interface• The system is incomplete with three ports unconnected.Figure 2: The AMESim model with the interface block.The force representing the damping in the suspension will be provided by Simulink andthe output from the velocity transducers will be sent to Simulink. To complete the systemit is necessary to add a special interface icon. Figure 2 shows this block added to the system.Figure 3: First step in creating the interface icon.To create the interface blocks, click on the Interface pulldown menu shown in Figure 3.This menu is designed to be used with the Simulink interface and other interfaces but inour case it will be Simulink. Select the item labeled Create interface icon. This is used todefine the variables which are provided and received by the companion software. FromAMESim these variables are seen as inputs and outputs respectively. The dialog box8
shown in Figure 4 is produced.Figure 4: Interface Icon Creation dialog box.MATLAB/Simulink interface 4.2User ManualNotice that in this figure there is a field with the label Adams in it. This must be changedby clicking on the arrow in the right of the field and by selecting Simulink as in Figure 5.There is currently no input and output variable. By selecting the arrow buttons in the topcorners, the number of input or output variables can be adjusted. You can have any numberincluding 0 but a reasonable upper limit is 10. If you want more than this, it is better to usemore than one interface block. In our example, we require two input variables and oneoutput variables, so ensure that the fields have the values 2 and 3 respectively.The next stage is to get AMESim to create a specific icon for the interface. The number ofports is now specified but it is also necessary to add a label to each port. Hence, we will addtext to give a name to the variables. In addition, we will give a general name for the wholeinterface block. Figure 5 shows text added in this way. Select each field and type an9
