Planning and requirements for various component endurance tests.

| Your suggestion of combining the spring endurance test with the shock absorber endurance test will be followed. In the Vauxhall spring endurance test the springs are stroked equally either side of the normal load position. This position is found from a load deflection test on an Olsen spring test machine. There is no spring test machine at B.U. I think we ought to have one. In addition to its use in determining spring opening and settling on endurance tests it would be very useful for checking experimental springs against the drawings. Vauxhall were not infrequently supplied with leaf spring whose ratewere more than 10% out from the drawing. An error of this magnitude can have quite an effect on the ride of a car. With regard to tests on engine components some rearrangement of the set up described in my earlier note seems desirable so that tests can proceed on more than one component at a time. The fan belt test discussed above could also be used for tests on water pumps. Tests on oil pumps, fuel pump and oil filters will be done with the two variable speed A.C. motors which were used on car oil pump tests in H.Halls shop. Endurance tests on valves, springs, and seats will require a new 30 H.P. variable speed motor and bed plate. This rig will also provide the suction for air cleaner tests. Below are two lists of test rigs. The rigsin list No.1 will require all the motors and bed plates which were obtained for car work in H.Halls shop. The rigs in list No.2. will require new motors and test rigs. Cont'd.{John DeLooze - Company Secretary} | ||
