Abstract The high-pressure axial piston pump is widely used in the field of coal machinery equipment due to its compact structure, high power density, and easy variable control. Failure affects performance. In this paper, sliding shoe pair plunger taken as research object, variation law oil film pressure numerically simulated by Matlab software, test bench built. full-cycle dynamic evaluation i...

The paper studies a series-parallel hybrid powertrain configuration for the medium-duty plug-in hybrid trucks and Volt-like passenger cars. The series-parallel hybrid combines the features of the parallel hybrid and the series hybrid. Series-parallel hybrid powertrains with preand post-transmission configuration for the plug-in hybrid medium-duty trucks were modelled and compared with a convent...

Introduction. The article deals with the problem of calculating strength shaft wheel drive agricultural machinery. conditions both maximum torque and values relative deformations are taken into account. Aim Article. Of research is to determine limits external influences on a structural element, caused by distributed weight motor-tractor machinery, at which it necessary construct not only strain...

The impact of converter control strategies on the drive train of wind turbines during voltage dips is investigated in this paper using a full electromechanical model. Aerodynamics and tower vibration are taken into consideration by means of a simulation program, named FAST. Detailed gearbox and electrical subsystems are represented in MATLAB. The dynamic response of electromagnetic torque and i...

F1F0 ATP synthase (ATPase) either facilitates the synthesis of ATP in a process driven by the proton moving force (pmf), or uses the energy from ATP hydrolysis to pump protons against the concentration gradient across the membrane. ATPase is composed of two rotary motors, F0 and F1, which compete for control of their shared γ -shaft. We present a self-consistent physical model of F1 motor as a ...

With the help of SolidWorks automated design system, analytical studies rolling machine with complex spatial movement working capacity “Turbula” type, which contains an additional moving link slider in its kinematic chain, were performed. On basis studies, relationship between change modes array middle container, value angular velocity drive shaft, scale standard size and ratio interaxial d...

Sun tracker technology is one of the mechatronic devices to optimize electrical energy rays from sun's by directing solar panel plane follow direction. This research aims design and manufacture an effective dual axis sun so as maximize absorption energy. The benefits provide a concept mechanical prototype with capacity 200 Wp which able detect light sources using CSD60-B DC motor in driving sys...
