Embodiment 1

[0030] Step 1. Determine whether the power cabin is in a normal state or a fault state, and obtain each fault probability q 1 to q 11 .

[0031] 1-1. On the existing power cabin comprehensive test bench, the power cabin is connected to the computer measurement and control system through various sensor interfaces. On the computer, the parameters that can be read directly include: diesel flow, output speed, output torque, Engine oil pressure, engine oil temperature, water temperature, fan pump inlet pressure, fan pump outlet pressure, a total of 8 input parameters, denoted as A 1 , A 2 ...A 8 . The common faults in the power cabin include: engine misfire, poor engine idle speed, engine weakness, engine overheating, abnormal oil pressure, oil leakage, increased fuel consumption, and faults between various shafts of the gearbox (a total of 7 gears in the gearbox, including one) Reverse gear, a total of 4 fault states). There are 11 kinds of fault states in total for the abov...

Abstract

The invention relates to a method for evaluating comprehensive performance of an engine compartment of an armored vehicle, and belongs to the technical field of automatic detection. The method comprises the following steps: the performance evaluation is performed on the engine compartment by utilizing fault prediction probabilities obtained during fault diagnosis; quantitative things are quantified by means of ideas of analytic hierarchy process; finally, performance of different engine compartments can be evaluated objectively and fairly, so as to intuitively show the performance of different engine compartments. The method can accurately evaluate the performance of the engine compartments identical with actual situations, and also provides reference significance for improving the performances of the engine compartments.

Description

technical field [0001] The invention relates to a comprehensive performance evaluation method for a power cabin of an armored vehicle, belonging to the technical field of automatic detection. Background technique [0002] The power compartment of an armored vehicle is an integrated machine that includes an engine and a gearbox. It is the core component of the entire vehicle, and its performance largely determines the overall performance of the armored vehicle. The power cabin is composed of a gearbox and an engine coupled. The engine converts chemical energy into mechanical energy. The gearbox is composed of a hydraulic torque converter, a planetary gear and a control system to achieve the purpose of variable speed and torque. Before vehicle assembly, a comprehensive performance evaluation of the power cabin must be carried out. Only products with qualified performance can be used for vehicle assembly. Therefore, it is necessary to evaluate the performance of the power cabin...
