Optimal Control of Gun Recoil Using Magnetorheological Dampers
Volume 2: Mechanics and Behavior of Active Materials; Integrated System Design and Implementation; Bio-Inspired Materials and Systems; Energy Harvesting, 2012Optimal control of a gun recoil absorber is investigated for minimizing recoil loads and maximizing rate of fire. A multi-objective optimization problem was formulated by considering the mechanical model of the recoil absorber employing a spring and a magnetorheological (MR) damper.

Detection and Control of Bubble Entrapment During the Recoil Phase of Droplet Impact
2020 IEEE 33rd International Conference on Micro Electro Mechanical Systems (MEMS), 2020In this paper, we report a method to detect the formation of bubble during the recoil phase of droplet impact on a (super-)hydrophobic surface using a MEMS-based acoustic sensor. We show that by this method, not only the occurrence of bubble entrapment can be detected but also the size of the bubble can be measured from the frequency of the oscillation

Notice of Retraction: Research for fuzzy control system of recoil tension
2011 Second International Conference on Mechanic Automation and Control Engineering, 2011According to researches recoil tension about automatic control system, through the current regulator to control the system. Not only keep the dynamic and static better, but also make interference immunity better. It avoids the shape tower in the process of recoiling, so it can accomplish rather better control result, satisfy the request of customers.

An adaptable computer control system for the Daresbury Recoil Separator
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1986Abstract This paper describes a computer system for the setting and control of all the magnets and high voltage supplies of a many element spectrometer using an LSI11/23 running RT11 with CAMAC input/output. Magnetic field strengths are measured by an inexpensive and easily constructed system of Hall probes and temperature transducers.

Effect of Mud Shedding on Riser Anti-Recoil Control at Emergency Disconnect
Volume 3: Pipeline and Riser Technology, 2012With drilling capability extends to water depths up to 3000m, significantly increased is the risk associated with a failed riser recoil control in the event of an emergency riser disconnect due to loss of vessel station keeping. In deeper waters the tensioner system undertakes higher top tension due to the accumulation of riser length and mud weight ...

An Anti-recoil Force Attitude Control Scheme of UAV for Insulator Washing
2020 Chinese Automation Congress (CAC), 2020In this paper, a nonlinear robust attitude control method for unmanned aerial vehicle(UAV) is proposed based on backstepping. First, the dynamic equations of UAV are established according to its motion model. Second, the momentum theorem and the Bernoulli equation are applied to model the recoil force.

The Journal of Chemical Physics, 2000
A quantum mechanical treatment of the photofragment angular momentum polarization following photodissociation of diatomic molecules is presented. This treatment extends that of Siebbeles et al. [J. Chem. Phys. 100, 3610 (1994)] by considering photodissociation of a molecule whose angular momentum is polarized in the laboratory frame, and also treats ...
