Experimental evaluation of cable drum systems as linear motion sensors

2011-04-15
This study evaluates cable-drum mechanisms as linear motion sensors for certain CNC applications. In this work, the dynamical attributes of a generic device are studied experimentally. The conducted research indicates that despite the significant traction force induced between the cable and its drum, small fluctuations in mechanism's speed yields a considerable (micro) slip at the interface.

TESTING, MODELLING AND SIMULATION OF LINEAR AND CIRCULAR LINEAR SHAPED CHARGES
Top, Mert; Dal, Hüsnü; Yıldırım, Raif Orhan; Department of Mechanical Engineering (2022-7-28)
In this thesis, testing, modelling, and simulation studies of the Linear Shaped Charge (LSC) and Circular Linear Shaped Charge (CLSC) are presented. CLSC is an alternative design to the Flexible Linear Shaped Charge (FLSC). It contains a copper liner and metal housing which are designed and produced by considering the target profile. Then, a molten explosive (PBX-110) is cured inside the copper and housing, so the CLSC production is completed. By following this production method, different LSC and CLSC conf...
Free vibration characteristics of a 3d mixed formulation beam element with force-based consistent mass matrix
Soydas, Ozan; Sarıtaş, Afşin (2017-09-01)
In this analytical study, free vibration analyses of a 3d mixed formulation beam element are performed by adopting force-based consistent mass matrix that incorporates shear and rotary inertia effects. The force-based approach takes into account the actual distribution of mass of an element in the derivation of the mass matrix. Moreover, the force-based approach enables accurate determination of free vibration frequencies of members with varying geometry and material distribution without any need for specif...
Active vibration suppression of a flexible beam via sliding mode and H ∞ control
Itik, Mehmet; Salamci, Metin U.; Demet Ulker, F.; Yaman, Yavuz (2005-12-01)
n this study, sliding mode and H. control techniques are applied to a flexible beam in order to suppress some of the vibration modes. The beam is a clamped-free flexible structure having piezoelectric (PZT) patches as actuators and a laser displacement sensor for measuring the tip point deflection. The beam is modeled in two different ways for each control algorithm. To implement sliding mode control (SMC), Euler-Bernoulli beam model is used and a finite dimensional LTI model is formed by using assumed mode...
Sparse linear sensor arrays: analysis of recent coarray based arrays and array design for nonlinear processing
Epçaçan, Erdal; Çiloğlu, Tolga; Department of Electrical and Electronics Engineering (2021-9-09)
In this thesis, sparse linear sensor arrays have been studied. The study of sparse arrays in this work can be considered under two main headings: Analysis and comparison of recently proposed coarray based arrays, and the adaptation of the nonlinear apodization method for linear arrays and its use in sparse linear array design. Recently proposed coarray-based sparse arrays are designed with closed form structures without the need for any optimization and have much higher degrees of freedom (DOF) than a unif...
Measurement correction of a set of analog sun sensors via neural network
Sozen, Semsettin Numan; Gokce, Murat; Yavuzyilmaz, Cagatay; Gulmammadov, Farid; Söken, Halil Ersin (2021-06-23)
A Neural Network (NN) based method to improve the accuracy of a set of analog Sun sensors is presented. Analog Sun Sensors are commonly used on satellites due to their reduced cost, small size and low power consumption. However, especially in Earth imaging satellites, they are prone to the Earth albedo effects. Magnitude and direction of albedo change depending on the reflection characteristics of the Earth's surface, position and attitude of the satellite and position of the Sun. The albedo may deteriorate...
