Attached are the first results obtained from the chassis vibrating rig at Shardlow. We think this machine is going to be very useful, as it certainly reproduces effects felt on the road at speeds up to 70 or 80 m.p.h., particularly with regard to the complaints of steering column movement which have been made by French and Belgian customers. In conjunction with this rig we are of course doing torsion tests on chassis frames statically, but this jiggling rig is much more effective in showing us which way to move. We shall shortly be running tests on various reinforcements on the Bentley chassis. As a result of these tests we are fitting B-56-BN{W.O. Bentley / Mr Barrington}, the steel-bodied car, with single piece wings and running boards, as this seems to be the one immediate move we can make to reduce the steering column movement. The rig is being improved by the addition of a more sensitive speed adjustment. Hs{Lord Ernest Hives - Chair}/Ra. Att: Hs{Lord Ernest Hives - Chair}/PJH.25/KW.13.9.35. with print. | ||
