| Alternative Rig Tests In order to help development the springs might be tested on a scraggy machine instead of on the bump test. This is just as severe. The springs must stand 200,000 to 250,000 cycles on this apparatus. We are designing a shock damper test rig which might be used as an alternative for endurance running. as yet we have no idea how severe the test will be. The disadvantage of the bump rig for development of, say, spring interleaving is that quite possibly 4 sets of interleaving may have to be tested for 100 hours & this will break up two complete | ||
