A semi-physical simulation system of separation guide mechanism

Abstract

A semi-physical simulation system of a separation guide mechanism, including a tooling platform, an upper-level engine simulation boundary, a lower-level shell segment, a separation motion loading system, a load loading system, a separation motion control system, and a separation motion data acquisition system. The upper-level engine simulation boundary is fixed on the tooling platform, and the lower-level shell segment and the upper-level engine simulation boundary are socketed through a separation guide mechanism. The separation motion loading system controls the separation of the next-level shell segment from the upper-level engine simulation boundary. The load loading system provides harsh additional loads for the next shell segment. The separation motion control system provides separation signals to the separation motion loading system, and provides load loading signals to the load loading system. The separation motion data acquisition system collects and analyzes the data during the separation motion process, and analyzes and evaluates the separation motion characteristics of the separation guide mechanism. The invention improves the development efficiency, shortens the development cycle and reduces the test cost.

Description

technical field [0001] The invention relates to a semi-physical simulation system of a separation and guidance mechanism, which belongs to the technical field of test simulation verification of aerospace separation and guidance mechanisms. Background technique [0002] At present, the flight mission of aerospace payloads is usually achieved through the launch of multi-stage launch vehicles. The connection and separation between the upper-stage engine and the lower-stage shell of a multi-stage launch vehicle is an important structural and functional element. The upper-stage engine and the lower-stage shell section are generally connected in the form of axial butt joint, and the larger-sized nozzle of the upper-stage engine is wrapped inside the lower-stage shell section. When the next sub-stage flight task is completed, the upper-stage engine is separated from the next-stage shell section. During the separation process, multiple sets of separation rockets inside the lower-st...

Problems solved by technology

[0003] Traditionally, to solve the above requirements, the separation power is generally provided in the form of "real product + simultaneous ignition of multiple groups of separation rockets" in the open and safe outdoors for test verification. There are large site area occupied, long preparation period, high test cost, and verification schemes. Once unsuccessful, problems such as design repetition and test repetition will seriously affect the development progress and design efficiency
