The embodiment of the invention provides an automobile altitude simulation system and test equipment. The system comprises an altitude test cabin, a control module, and an air inlet vacuum fan device and an exhaust vacuum fan device which are electrically connected with the control module, and the air inlet vacuum fan device and the exhaust vacuum fan device are both connected with the altitude test cabin through a pipeline; in the process that the altitude test cabin is adjusted to reach the target altitude, if the environmental altitude is lower than the altitude of the altitude test cabin, the air inlet vacuum fan device generates electric energy under the action of airflow generated by pressure difference, and the electric energy is integrated by the control module and then supplies power to the exhaust vacuum fan device. If the environmental altitude is higher than the altitude of the altitude test cabin, the exhaust vacuum fan device generates electric energy under the action of airflow generated by pressure difference, the electric energy is integrated by the control module and then supplies power to the air inlet vacuum fan device, and in the process, one vacuum fan can consume the electric energy all the time, and the other vacuum fan generates the electric energy all the time; therefore, the purposes of power generation and energy conservation of the system are achieved.
Description
technical field [0001] The invention relates to the technical field of automobile testing, in particular to an automobile altitude simulation system and testing equipment. Background technique [0002] The automotive environment simulation laboratory is used to test the performance of the car under different environmental conditions such as temperature, humidity and pressure. With the gradual development and maturity of the automobile industry, in order to enhance brand competitiveness, automobile manufacturers have an increasing demand for automobile environment simulation laboratories in the stage of automobile performance research and development. capabilities are playing an increasingly important role. [0003] In the existing automobile altitude simulation experiment system, the air intake part is mainly through the throttle valve, and the external normal pressure air is throttled and then sent into the laboratory, and the exhaust part is pumped to the Negative pressu...
