By taking notice of configuration of bolted joints in a car's wheel hub, a loosening test machine is proposed. This machine can be said to be circular vibration type. The constructed one has 4 test places located at equal angle intervals on the circle of 100mm diameter and its vibration angular amplitude is variable in 40 steps with upper limit of 0.5°. And it is exclusively for the bolts and nuts of 10mm nominal diameter and the maximum frequency of test vibration is 1Hz. With this machine, it is possible to perform loosening tests about 4 sets of test bolts and nuts at the same time and consequently, it is convenient for comparison tests under the same condition. Experimental results obtained tentatively is presented and considered.
