Determination of the influence of the stiffness of the diesel engine suspension cushions in the terrain car

The article presents the results of experimental investigations carried out for different types of diesel engine suspension cushions in the terrain car. The study was performed using two types of suspension cushions in a variety of combustion engine operating conditions. The effect of engine displacement as a result of vibrations between the engine and vehicle body was tested. The endurance testing of the suspension cushions was done using the endurance testing machine Zwick Z-100. Next, we analyzed the results obtained in experimental studies of the differences between the vibration of the suspension cushions. The results of the tests of different types of plate connectors for the engine suspension can be useful when designing propulsion systems for military vehicles and military utility terrain cars, or as shown by the author [1, 4] to modernize of the existing military vehicles stock.
