Lunar Roving Vehicle Wheel Assembly Testing

Lunar Roving Vehicle Wheel Assembly Testing

For example, driven on a rolling road fixture, the wheel assembly was tested under Earth conditions and later in test chambers, reproducing the environmental conditions on the moon. The LRV tires are made of a woven mesh of zinc-coated piano wire to which titanium threads are riveted in a chevron pattern to keep the wheels from sinking into the soft lunar soil. Long-duration torture testing on this so-called carousel, simulating the lunar surface, verified the durability of the wheel design. The test assembly was supported by springs to relieve most of its weight, thus simulating the one-sixth gravity of the moon.
