Project 1

Q1)-

Ans- Model:- SCREENSHOT-(161)

• double-acting actuator with cylinders.
• first we are using the sine wave to generate the signal .
• than we are using simulink to ps converter and connect to the three way directinal valve.
• than we are using pump.
• The pump output is connected to cylinder B of the actuator while cylinder A of the actuator can be connected to either the pump or the reservoir through the 3-way directional valve.
• When cylinder A is connected to the pump, pressures at both cylinders become equal.
• Because of the larger effective piston area in cylinder A, the interface force in cylinder A is larger than that of in cylinder B which causes the piston to extend.
• When cylinder A is connected to the reservoir, the piston starts to retract. The 3-way directional valve is controlled by a sinusoidal signal to achieve repeating reciprocal motion in the actuator.
• than we are using the signal builder as the rename to Torque.
• than we are using simulink to ps converter and connect the one end is signal builder and other end is connect to the torque sensor.
• than we connect to the ideal torque sensor s-port.and other end like c port side we connect the mechanical rotational referance.
• than we connect the torque source to the inertia block.and connect to the R- port to fixed displacement block.
• than we are using the Fix- displacement block having the ports name as R,C,B and A.the A port is connected to the Reservoir and pressure relief valveand the B port are connect to the pump.and C - port are connect to the the pump.
• than we are using the Reservoir to source of the energy.
• than we connect the pressure relief valve to stop the pressure and relise the pressuer.
• we are using the thermal setting block and one solver and connect them into the preesure relief block and local restriction block.
• the restriction block having the two port A and B, THE A side are connect the solver and the B side is connect to the Double acting Actuator B port.
• than we are using the Double Acting Actuator having the different ports name as the A,C,R,B,P,HA and HB, than the R port is connected to the mechanical load and P port is connected to the ps-simulink converter, where HA port is connected to the Enviroment block which is subsystem and the HB-port is connected to the mechanical load, than C-port is connect to the translational mechanical referance Block.

MECHANICAL LOAD BLOCK :- SCREENSHOT(165)

• Here we are using the mass block and connect to the translational Damper and the translational spring.
• the we are using the Mechanical Translational Reference Block.
• and we give the input block name as R.

ENVIROMENT :- SCREENSHOT(164)

• Constant Block having the value is 293.15 and rename the block Enviroment temperatuer block. and connect to simulink to ps converter.
• than we are using ideal Temperature source block having difeerent ports A,B and S, s is connect to the simulink to ps converter than A- port si connect to T-ref and port B - is connected to covective heat Transfer.
• than we are using the convective heat transfer block and connect to the conductive heat transfer block port-B.
• than we are using cylinder mass block of the conductive heat transfer block.and connect the convective heat transfer block at in the parallel manner.

RUN THE MODEL :- SCREENSHOT(163)

• check all the connection and Run the simulation for 100sec than we get it started from zero than it move the constantly then after 5 sec than its start Rapidly increase the graph and its form the some square shape type wave formation.
