Getting Started Using Adams/Car Ride 10 Running a Swept-Sine Analysis In this section, you perform a simulation using a basic ride input: a vertical swept-sine displacement disturbance of the tires. Opening the Assembly You first open the assembly on which you will perform the analysis. To open the assembly: 1. From the File menu, point to Open , and then select Assembly . 2. Right-click the Assembly Name text box, point to Search , and then select <aride_shared>/assemblies.tbl . 3. Double-click Vehicle_full_4post_PAC2002.asy . 4. Select OK . Setting up the Analysis Now that the assembly is open, you are ready to set up the analysis. To set up the analysis: 1. From the Ride menu, point to Full-Vehicle Analysis , and then select Four-Post Test Rig . The Full-Vehicle Assembly text box displays the name of the assembly, Vehicle_full_4post_PAC2002 . 2. Enter the following specifications: Output Prefix : swept_heave End Time : 10 Mode of Simulation : interactive Basis for Number of Output Steps : min. number of outputs per input Target Value for Basis : 20 To prevent errors caused by aliasing, sample outputs at a minimum of six times the highest input frequency. A ratio of ten is much better than six; 20 is very good. Never use a ratio less than six.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
