The torque motor is a precision mechatronic component used to convert low electric signal into linear mechanical displacement of the Jetpipe. Such torque motors are categorized under multi disciplinary engineering systems, which are complex in nature and also induces challenges to integrate with hydraulic system. This paper applies model-based system design approach of jetpipe servovalve torque motor to study the effect of critical parameters like armature length and air gap, feedback spring stiffness, and flexure tube stiffness on the dynamic performance of the were studied.

This paper designs a bi-directional hydraulic lock used in a large flow hydraulic system for controllable pitch propeller. The lock is used to resist the hydraulic cylinder shifting when the pitch reaches the presetting situation. The structure parameters of the lock are obtained by static design, and the dynamic performance of it is analyzed by modeling and simulation with the system on rated load. The dynamic simulating discovers the faults of the lock designing by static calculating and the results provide sufficient supports for its parameters optimization.

Hydraulic disc brake is essential for meeting the requirements of safety and economic efficiency during drilling and work-over procedure. To address this need, we have developed a programmable logic controller controlled novel hydraulic disc brake system with capability to apply control strategy similar to anti-lock braking system for hoisting system of truck-mounted drilling rig. This paper is to investigate the complicated interaction between the work clamp and the hydraulic control system. So designers can use this model to decide which control strategies are more suitable for the disc brake. This is demonstrated by modeling the advanced hydraulic system and simulating influential factors on dynamic characteristics of hoisting system disc brake, with the application of the Advanced Modeling Environment for Simulations of Engineering Systems. The method of modeling and simulation provides a simple, effective approach to studying hydraulic disc brake for hoisting system.

Working Situation

Rake-car’s driving system of ore reclaimer originally used crank and connecting rod mechanism as driving mechanism. The driving mechanism got some trouble that parts got severe wear and failure rate of mechanism was high. The hydraulic system is used to drive rake car in view of hydraulic driving system’s advantage. By analysis on existing problem of crank and connecting rod mechanism, the actual working load of equipment is tested and the working situation is analysed. The working situation of the hydraulic system is also analysed by computer simulation. By optimization of the hydraulic system design, the final design is determined. The whole system is actually used. It works well.

Energy Balance Approach

The purpose of carburizing, nitriding and carbonitriding is to increase the strength of components. Elements such as carbon, nitrogen and carbon-nitride are diffused into the components at high temperature convective environment. The amount of diffusion is to be regulated by controlling the temperature and time of diffusion. Time and temperature of process govern diffusion rate and strength of the component. Numerical modeling is applied by energy balance approach i.e., equating rate of change of energy is equal to energy transferred by conduction, convection and radiation. By non dimensionalising relations for the mentioned critical parameters were obtained. The phenomenon of convection, radiation and conduction are taken together for the purpose of numerical modeling. Variation of temperature and depth of diffusion of component for the taken components i.e., sphere and cube was plotted in transient state. For both numerical analysis and simulation the boundary conditions i.e., for carburization the ambient temperature is 9500C with carbon monoxide as the carburizing agent and for nitriding the ambient temperature is 5300C with nitrogen as nitriding agent and the component taken is of steel which is initially at room temperature were taken. Results obtained from numerical modeling and simulation were compared with each other and observed that in both analyses the variation of temperature with time and depth of diffusion is almost linear. Final differential equation obtained in numerical modeling is a single order non linear differential equation which is solved in MATLAB using finite difference approach. Data obtained from MATLAB were plotted for variation of surface temperature and geometric dimension with respect to time.
