TABLE 1 comprehensive DMEA analysis Table

Specifically, a missile weapon equipment damage mode and influence analysis method considering battle threats, special events and technical processes, as shown in fig. 1, includes the following steps:

first step analysis of Damage mechanism

The damage mechanism refers to all possible conditions or condition combinations such as enemy attack which may cause equipment damage, behavior factors such as attack enemy or combat environment, special events, and technical processes adopted by equipment in the processes of combat, training, maintenance, use guarantee and the like.

According to the equipment life profile, the mission profile and the environment profile, the damage mechanism analysis is carried out from three aspects of combat threats, special events and technical processes, and the damage mechanism types and relevant factors are shown in a table 2:

(1) a combat threat refers to all possible causes or factors of equipment damage in a battlefield environment due to an enemy attack, attacking an enemy or the combat environment.

(2) Special event classes refer to abnormal use actions or unexpected conditions that lead to unexpected damage to equipment during the life cycle.

(3) The technology process class refers to technologies and process conditions that are sensitive to potential damage employed in the design and manufacture of equipment.

TABLE 2 Damage mechanism

Second step determination of injury patterns

All task stages and working modes of the equipment are analyzed according to the service life section and the task section, and typical task stages and working modes of the missile weapon equipment are shown in a table 3.

On the basis of comprehensively decomposing and identifying the task stage and the working mode of the equipment, various damage mechanisms are superposed on each task stage and working mode in the using process of the equipment, and all possible damage modes of the equipment caused by the action process of the fighting threat, the special event and the specific mechanism of the technical process in each task stage and each working mode are analyzed and identified one by one; typical injury patterns are shown in table 4.

Analysis to determine damage patterns should be done with care to distinguish them from failure modes, which are typically intrinsic failures caused by the failure mechanism of the product itself or the system, whereas damage patterns are often extrinsic failure modes due to battlefield conditions, abnormal use, abnormal conditions. Since the fuel tank rarely malfunctions during the normal life cycle of the missile launcher, the failure mode of the fuel tank is not important for analysis in failure mode influence and hazard analysis (FMEA), but when the fuel tank is subjected to damage mode analysis, the fuel tank is exposed to a large area and accumulated energy, and is likely to be severely damaged by various attacks, and thus the damage mode is to be analyzed.
