Abstract

The invention discloses a power compartment simulation system. A first alternating-current (AC) variable-frequency motor, a first torque meter, a first hydraulic pump, a first bracket and a first hydraulic motor are sequentially connected with one another; a second fan, a second hydraulic motor, a second bracket, a second hydraulic motor, a second torque meter and a second AC variable-frequency motor are sequentially connected with one another; a third AC variable-frequency motor, a third torque meter and a driving water pump are sequentially connected with one another; an air inlet shutter, an air outlet shutter, the first fan and the second fan are arranged in a simulated power compartment chamber; and a heat radiator, a power compartment simulation device and the driving water pump are in series connection through a primary cycling water channel. According to the power compartment simulation system, equipment of a power compartment can be simulated, and the equipment has the same flow and heat-transfer conditions as that of real equipment. With the adoption of the power compartment simulation system, the physical and chemical properties of real media can be obtained, and the real working conditions of the power compartment in working can even be simulated, so that the problems of singleness in heat source media, uniqueness in simulation quantity and no adjustability in temperature and flow of the general power compartment simulation system are solved.

Description

technical field [0001] The invention relates to a simulation system, in particular to a power cabin simulation system. Background technique [0002] As the heart of the vehicle, the engine plays a vital role in the performance of the vehicle. The heat dissipated by the engine when it is working is approximately equal to the effective power it outputs. Therefore, the internal environment of the engine power compartment where the engine and its auxiliary systems are located plays an important role in the heat dissipation of the engine. With the development of engine technology, on the one hand, the engine power continues to increase, requiring a larger amount of cooling air; on the other hand, due to the needs of shape and aerodynamics, the space of the engine power compartment is getting narrower, and the air intake space Constraints on layout location are also increasing day by day. In order to ensure the flow and heat transfer of the cooling system in the engine compartme...
