The paper considers the problem of improving the comfort and environmental friendliness of a modern f-segment car with an internal combustion engine by reducing the noise and vibration levels of the exhaust system. Gas-dynamic and mechanical excitations from the car engine and road surface cause vibrations in the exhaust system, which are transmitted through the body and the bracket structure to the body causing discomfort of the driver and passengers. To reduce the negative impact, when designing the exhaust system, it is necessary to ensure such a location of the exhaust system suspension elements that will meet the maximum operation requirements for the vibration comfort. An important task is to build a numerical experiment for the entire assembly structure to determine the nature of the similar systems loading. The solution of the above tasks is aimed at the insurance of specific strength and durability of both the entire system as a whole and the most important support elastic elements. This calculated study is of practical importance not only for reducing the vibration load of car exhaust systems and the car body, but also for improving the vibro-acoustic comfort of passengers.
