Health prediction method, system and storage medium of tracked chariot transmission mechanism

Abstract

The invention relates to a health prediction method, system and storage medium of a speed change mechanism of a crawler chariot. The health prediction method of the speed change mechanism of the tracked chariot includes: using the gray relational analysis method to determine the health characteristics of the operating data in the target domain, the health characteristics of the operating data in the source domain, and the health characteristics of the speed change mechanism in the source domain according to the monitoring data set. Dimensional health indicators, determine the health characteristics of the operating data in the target domain and the DTW distance between the one-dimensional health indicators, determine the public performance characteristics between the target domain and the source domain according to the DTW distance, construct a public feature set, and adopt improved fish swarm optimization SVR synthesis The transmission health prediction model uses the public feature set as input to determine the health degree prediction result. Based on the prediction flow provided by the invention, the health state of the equipment and the change trend of the health state can be quickly judged, and the analysis time of the maintenance staff is saved, and meanwhile, it has the advantages of accuracy, strong fault tolerance, and high flexibility.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission of a tracked combat vehicle, in particular to a health prediction method, system and storage medium of a speed change mechanism of a tracked combat vehicle. Background technique [0002] As a key component of the chariot, the integrated transmission device transmits the power generated by the engine to other power components of the chariot to realize functions such as forward, backward, steering, braking, and speed change. Its performance status directly determines the maneuverability of the chariot. Capability, which in turn affects the combat capability of the tank, is also one of the factors to measure the high reliability of the tank. As a highly complex electro-hydraulic system integrating multiple sensing technologies such as hydraulic force, hydraulic pressure, and planetary transmission, the integrated transmission device has a large structure, complex failure mechanism, di...
