Justification of tractor cab mounting support selectio n K-525Pr by parameters of vibration loading

The article is devoted to an experimental assessment of the feasibility of using alternative vibration damping supports for mounting the engine, gearbox and cab of the K-525Pr tractor, selected instead of the regular ones under the import substitution program of Western European suppliers. The main evaluation indicator is vibration acceleration at the workplace of the driver—operator. Three sets of supports were tested in comparison with the serial ones. Based on the results of tests compared with each other and with the normatively established vibration load parameters, recommendations for choosing an alternative supplier are substantiated.
