“…In the process of pressure container packaging being impacted by explosive loads, the dimension analysis method can be used to establish a dimensional relationship between the peak pressure of the witness plate and other physical parameters during the impact process. It involves analyzing and determining the general laws that govern the quantitative relationships between different physical quantities by considering their dimensional forms [7] .…”

As the protective body of the pressure container, the reliability of pressure container packaging directly determines the safety of the pressure container. Therefore, the explosion-proof performance of pressure container packaging is crucial. In order to measure the explosion-proof performance of pressure container packaging, witness plate pressure is used to measure the explosion-proof performance of pressure container packaging, and a method based on dimension analysis is proposed to establish a mathematical model of the explosion-proof performance of pressure container packaging. This model quantitatively solves the nonlinear relationship between the peak pressure of the witness plate and the number of pressure container packaging layers, pressure container packaging thickness, and packaging materials. Applying this to the design of pressure container packaging can provide a reference for improving the explosion-proof performance of pressure container packaging.

The centering mechanism of the nose landing gear is crucial for aircraft operational safety, particularly during the takeoff and landing processes. To address the failure of the return function observed in a certain aircraft, this paper establishes a dynamic model that can effectively characterize the return motion characteristics of the landing gear, considering the synergistic effect of the landing gear buffer device, the shimmy damper, and the centering mechanism comprehensively. On this basis, the four key parameters are studied in depth, including the initial filling pressure of the buffer device, the friction moment of the shimmy damper, the damping coefficient of the shimmy damper, and the contact friction coefficient of the centering mechanism. The results reveal that the return driving moment acting on the piston rod of the nose landing gear increases slowly with the increase in steering angle. At the 90° steering angle, the peak value of the return driving moment is 43.97 Nm. Among the parameters studied, compared with the initial filling pressure and the friction moment of the shimmy damper, the contact friction coefficient of the cam has the most significant effect on the return function.
