Abstract:

Results are presented of road-shock and vibration studies on dummy packages simulating the radio set, ANGRC-106, Model SSB as installed rigidly and with isolators on the left sponson of an M38A1 truck. With the radio set in place, the vehicle was operated over a series of test courses. Accelerations were measured on the vehicle sponson and on the simulated radio sets for both conditions for study. Peak acceleration values measured during operation under conditions of rigid mounting were 2.5g vertically, 3.2g transversely and 3.3g longitudinally. Peak accelerations measured during conditions of isolated mounting were 3.1g vertically, 2.7g transversely, and 3.9g longitudinally. The maximum acceleration of 3.3g measured at the top of the ANGRC-106 radio rigidly mounted was excessive and was generally considered about normal response for gear transported on wheeled vehicles. Installation of isolators between the vehicle sponson and the radio set is not justified on the basis of these tests. Author
