The composite swing arm of Polaris was tested to failure. A testing rig was developed from which weight could be hung until the swing arm broke. The test rig is composed of a metal top plate bolted to an L-shaped lower metal plate (figures 1 and 2). Between these two plates is the composite swing arm.
The test rig was mounted to a forklift and weight was hung off the rig. In figure 3 a forklift was used to move four 250 lbs. plates used to test the part. In figures 4-7 the test rig is mounted on the forklift. Figure 7-9 show the fracture in the part after it has broken. The test rig is removed from the forklift in figures 10-12. Figure 13 is the composite swing arm after it has been removed from the test rig. In figure 14-16 the actual weight hung from the eyebolts attached to the test rig is determined. The team that conducted the testing is in figure 17.
