Problems solved by technology

However, these measurement methods require the development of special measurement equipment, which requires a long investment time and high development costs, and is not suitable for model development. Therefore, it is necessary to use a more economical and convenient method to measure the center of mass and mass deviation of the fairing.

Abstract

The invention relates to the technical field of centroid deviation measurement methods, in particular to a centroid deviation measurement method for conical cylindrical parts. The centroid deviation measurement method includes the following steps: measuring the axial centroid of a conical cylindrical part: placing the conical cylindrical part horizontally, arranging a first support and a second support at the front and back ends of the conical cylindrical part respectively, and determining the axial centroid of the conical cylindrical part according to the distances between and the weights ofthe conical cylindrical part, the first support and the second support; measuring the radial centroid deviation of the conical cylindrical part; and lifting the conical cylindrical part, measuring theobtained centroid position according to the axial centroid, and calculating the radial centroid deviation of the conical cylindrical part according to the triangular function relationship of the conical cylindrical part after lifting. The centroid deviation measurement method provided by the invention is designed for conical cylindrical parts, has certain universality for mass deviation measurement, does not need to develop special measurement equipment, has the characteristics of short investment time and low development cost, and can be used to complete the centroid deviation measurement ofconical cylindrical parts in an economical and convenient way.

Description

technical field [0001] The invention relates to the technical field of centroid-mass deviation measurement methods, in particular to a centroid-mass deviation measurement method for a cone-cylindrical member. Background technique [0002] The main function of the missile fairing is to protect the payload from harmful environments such as aerodynamic force, aerodynamic heat, and acoustic vibration during the flight of the missile in the atmosphere. When the missile flies to a certain altitude, the fairing separates and breaks away from the missile body, reducing the flight mass of the missile and making preparations for the payload to work. The flight path at the moment of separation of the fairing must be precisely staggered with the flight path of the missile to avoid collision and interference with the missile, and the center of mass and mass deviation parameters of the fairing have a crucial impact on its flight path. Therefore, it is of great significance to measure the...
