Abstract

The invention belongs to the technical field of automobile performance inspection, and discloses a simulation method and system for a vehicle road test of an intercooler. The method comprises the following steps: connecting the intercooler with a supercharged air simulation unit, and simulating a heating process that supercharged inflow air of an engine enters the intercooler; connecting the intercooler with a intercooler heat dissipation unit and simulating a cooling process that test ambient air enters the intercooler; and fixing the intercooler connected with the supercharged air simulation unit and the intercooler heat dissipation unit on a six-degree-of-freedom rack in a whole vehicle arrangement form, and simulating road and whole vehicle loads borne by the intercooler in the driving process of an automobile. According to the invention, the process that the inflow air of the engine heats the intercooler is simulated, and the process that the ambient air cools the intercooler is also simulated, so the temperature and air pressure environment of the intercooler is simulated, and the intercooler is fixed on the six-degree-of-freedom rack in a whole vehicle arrangement form so as to simulate road and whole vehicle loads borne by the intercooler in the driving process of the automobile; and thus, data acquisition under the driving working condition of the automobile is guaranteed.

Description

technical field [0001] The invention relates to the technical field of automobile performance inspection, in particular to a simulation method and system for an intercooler vehicle road test. Background technique [0002] The on-board intercooler is an essential part in the working process of the supercharged engine of the car. During the working process of the supercharged engine, the temperature of the air that is supercharged by the supercharger can rise to 160°C, or even as high as 200°C. At the same time, the supercharging capacity of the exhaust turbocharger is affected by the exhaust of the engine, which will produce periodic fluctuations in the rotational speed. This periodic exhaust change directly affects the change in the air pressure on the other side of the turbocharger, resulting in a similar Periodic fluctuations of the intercooler have an impact on the heat dissipation performance, sealing performance and structural reliability of the intercooler, especially ...
