Analysis and control of gun barrel vibrations

Büyükcivelek, Fırat
Modern battle tanks are equipped with gun stabilization systems using gyro and encoder data to stabilize the gun barrel, although these systems are very sensitive and reliable, these systems assume the gun barrel as a rigid beam, and do not use information from.


Design of a shock absorber for weapon systems
Canik, Erdem; Çalışkan, Mehmet; Department of Mechanical Engineering (2014)
Shock absorbing pistons, as the absorbers of the instantaneous shocks and the recoil forces of weapon systems embodying them, are subjected to very high forces. The pistons are required not only to decrease the recoil forces down to favorable values for the other components of the system to function properly and the operator to operate the system comfortable, but also they should not be destructively rigid considering the dynamics of the weapons. The majority of the shock absorber producers in the local mar...
Modelling and controller design of the gun and turret system for an aircraft
Mert, Ahmet; Leblebicioğlu, Mehmet Kemal; Department of Electrical and Electronics Engineering (2009)
Gun and gun turret systems are the primary units of the weapon systems of an aircraft. They are required to hit targets accurately during operations. That is why a complete, high precision control of weapon systems is required. This function is provided by accurate modeling of the system and the design of a suitable controller. This study presents the modeling of and controller design for the gun and turret system for an aircraft. For the controller design purpose, first the mathematical model of the system...

Electromechanical actuators are widely used in miscellaneous applications in engineering such as aircrafts, missiles, etc. due to their momentary overdrive capability, long-term storability, and low quiescent power/low maintenance characteristics. This work focuses on electromechanical control actuation systems (CAS) that are composed of a brushless direct current motor, ball screw, and lever mechanism. In this type of CAS, nonlinearity and asymmetry occur due to the lever mechanism itself, saturation limit...
Finite element modelling and analysis of recoil springs in automatic weapons
Zaloğlu, Hakan; Özgen, Gökhan Osman; Ciğeroğlu, Ender; Department of Mechanical Engineering (2013)
As a tool for weapon designers, a finite element based analysis methodology is developed for estimating the mechanical behavior of the recoil spring during a firing cycle. All models are developed in LS-DYNA to be used in analysis to estimate the nonlinear force deflection characteristics and dynamic stress in the spring during a representative firing cycle. An experimental study is also performed to validate the finite element based analysis methodology. Modeling, analysis approach and modeling parameters ...
Active Control of Smart Fin Model for Aircraft Buffeting Load Alleviation Applications
Chen, Yong; Ulker, Fatma Demet; Nalbantoglu, Volkan; Wickramasinghe, Viresh; Zimcik, David; Yaman, Yavuz (2009-11-01)
Following the program to lest a hybrid actuation system for high-agility aircraft buffeting load alleviation oil the full-scale F/A-18 vertical fin structure, an investigation has been performed to understand the aerodynamic effects of high-speed vortical flows on the dynamic characteristics of vertical fin structures. Extensive wind-tunnel tests have been conducted on a scaled model fill integrated with piezoelectric actuators and accelerometers to measure file aft-tip vibration responses under various fre...
