“…Dynamic model of the line throwing rocket system is based on the Kane's method [3]. Tiwari et al studied on a rigid body dynamics model for a representative howitzer system and used relatively simple experimental procedures to estimate principal design parameters of their dynamic system [4]. Tian et al compared the dynamic analysis of a crank connecting rod mechanism using the Adams program in a numerical method and compared it with the analytical solution of the system's motion equation [5].…”

In this study, the friction and damping values that arise during the deployment of the folded fin mechanism were obtained based on the experimental data. Although there are recommended values for friction in the literature, damping is a phenomenon that varies from system to system and must be obtained through test data. In this study, firstly, the mechanism was operated on the test device with a specific drive pressure and the actual drive pressure generated in the system was measured. The dynamic behaviour of the mechanism was recorded by a High-Speed camera system as well. Adams MBD (multi-body dynamics) was used to define the mechanism model and drive pressure data from the test was defined as input to the model. With the help of Adams DOE (Design of Experiments), certain intervals were defined for friction and damping, multiple analyses were carried out at the friction and damping intervals defined and total deployment time of the mechanism and the dynamic behaviours it exhibited during deployment were obtained. From these numerical results obtained, friction and damping values were obtained based on the model with the highest correlation and test results. The same mechanism was tested for different drive pressures with the specified friction and damping values and the results were compared to the numerical models. It was decided that the friction and damping values determined as a result of the comparison could be used in future numerical analyses.

“…Tiwari et al [1] modelled a rigid body dynamic of a howitzer with experimental characterization and performance analysis in which acceleration of the counter-recoiling barrel was measured using the accelerometer B&K 4517, with sensitivity of 10 mV/g and data acquisition was done using 24-bit resolution NI 9234 DAQ card, with voltage range of -5 V to +5 V. These acceleration data of the counter-recoiling barrel were integrated over time to get velocity and displacement. Jia et al [2] analyzed the recoil movement characteristics of artillery firing based on Symlet Wavelet Filtering technique whose recoil acceleration was measured by piezoelectric acceleration sensor YD-PC.…”

Measurements of recoil and counter-recoil movement in weapons are essential in order to optimize ballistic performances, to ensure safety during firing, to improve the accuracy and the effectiveness of the weapon during its life cycle and to guide design and development work. From this, the present work focuses on contact-based measurements of the counter-recoil movement of the D30J 122 mm howitzer using two inductive sensors, namely, displacement sensor and acceleration sensor. The measurements from the displacement sensor were used to calculate the velocity and acceleration of the counter-recoil by derivation and those of the acceleration sensors were used to calculate the velocity and displacement of the counter-recoil by integration. The comparison between the measured and calculated results obtained from the two sensors shows a very good similarity in form of variation and in values, which validates the applied experimental approach in this work and confirms the accuracy of both measurement methods.

“…The nonlinear finite element, orthogonal test method, and rigid body dynamics have been used to determine that the clearance between projectile and bore. [1][2][3][4] In the analysis of the dynamic process of firing, it has been determined that the deformation and dynamic response of a guided projectile is affected by the engraving force. 5,6 Procha´zka and Ninh 7 determined that a high temperature in the barrel walls causes more deformation than the mechanical load of the shot.…”

Internal ballistics of polygonal and grooved barrels: A comparative study

As a parameter important ballistic, the research about polygonal and grooved barrels’ behavior has not been widely carried out. The pressures, velocities, stresses, deformations, and strains generated by the firing of 9 mm × 19 mm ammunition in weapons with polygonal barrels are analyzed numerically and experimentally, compared with those generated in pistols with grooved barrels. The Finite Element Method with equal boundary and loading conditions was used in both types of guns, specifying the actual materials of the projectile and the barrels. Subsequently, experimental tests were carried out on various weapons with 9 mm ammunitions of 115, 122, and 124 gr. The results show that the 9 mm bullet fired in a polygonal barrel undergoes a maximum deformation towards its exterior of 0.178 mm and interior of 0.158 mm, with stress up to 295.85 MPa. Compared with 0.025 mm maximum external deformation and 0.112 mm internal deformation of 9 mm projectiles fired in a grooved barrel, with stress up to 269.79 MPa. The deformation in the polygonal barrel is in a greater area, but the rifling impression left is less deep, making its identification more difficult. Although there are differences in the stresses and strains obtained, similar velocity and pressure parameters are achieved in the two types of barrels. This has application in the development and standardization of new kinds of barrels and weapons.
