Marine Engineering Simulation and Modeling 21526/NM9512018 -2019Marine Engineering Simulation and ModelingCoursework•You should provide a comprehensive report following the numbering system on the questions. •You should also include an electronic copy of your programs.For each of the questions you should include:1.A full description of any mathematical models which you (may) have developed including FBD’s.2.A brief description of your Simulink model and how it works.3.A full discussion of the results obtained.4.Make sure that you run your model over an appropriate amount of time; the system wil default to only 10 seconds you wil often have to change this.Read the questions very carefuly.LO1 –Exam•2 Courseworks 50% each. •1stCoursework: Simulink Coursework –Report , Deadline wek 7. Marine Engineering Simulation and ModelingCoursework: Hydraulic actuatora)Build a mathematical model, for the single action hydraulic ram shown below. The surface area of the piston head is 0.1 m2. Mases !and &"are 10 Kg and 5 Kg respectively. Spring #has a stifness of 2 N/m while damper $has a friction of 1 N/m/s. (Include for the presence of leakage betwen the piston and the cylinder wal using leakage coeficient , %= 0.00001. The total leakage rate is m3. The bulk modulus of the fluid may be asumed infinite.)b)Plot the position, velocity, and aceleration of mas, &", for a step input flow rate of 0.1 m3/sec.c)Determine the time taken for piston to stop moving -increase the simulation time.d)By refering to the FBD of the system explain why the piston stops moving.e)What is the value of the leakage when the piston has stoped moving?The input flow rate is changed to a sinusoid of amplitude 0.1m3/sec and frequency π/40 rad/s.()*()&"0,()vent!#$f)Calculate and plot the cylinder presure.g)Calculate and plot the leakage flow rate and hence determine the volume of fluid which has leaked over 50 seconds of continuous operation.h)Discus your results.Marine Engineering Simulation and ModelingCoursework: Electronic Servo ValveA typical control system for an electronic servo valve is shown below. The system comprises a DC motor coupled to a mechanical valve. The input signal represents the instantaneous desired valve position. An input level of zero (0) comands the valve to close and an input value of one (1 ) comands the valve fuly open. The output represents the actual position of the valve. The relationship betwen the input and output depends on the physical parameters of the valve, the motor and the control system layout.The transfer function represents the dynamics of the motor and valve asembly:!&"#$#%()*= 0.01 Kgm2+&"#$#%()*,*(),= 0.1 Nm/rad/sec-&"(motor torque constant) = 0.1 Nm/Amp.a)Build a time domain model of the system and use only the simulation to investigate the efects of gains Ka, Kv, and Kpon the dynamic response of the servo valve. i.e. damping and natural frequency.b)Asuming the input is a step of magnitude 1,find apropriate values of Ka, Kvand Kp, so that the desired final position is obtained in les than 0.3 seconds with a maximum overshoot of les than 5%.Marine Engineering Simulation and ModelingCoursework: Tank Level Open Loop SystemWater flows into a cylindrical tank of cros sectional area 1.34 m2at a rate !&"#and out to the atmosphere through a capilary type restrictor at rate !$#.a)Build a model relating the depth of liquid in the tank, ℎ#to the input flow rate. Where !$#=0.8 ℎ#. The volume of the tank is 10 m3. There wil be two outputs, one indicating volume the other height of water. Before ading any sources or sinks to your model, select al the blocks, (CRTL-A), then using the edit menu on the tolbar create a subsystem. Label this system ‘Tank Dynamics’. Double clicking on the subsystem wil alow you to enter it. Do this and label the inputs and outputs accordingly. Return back to the uper level from the task bar. Now enter the sliders section in the dials and blocksetlibrary. Ad a tank to your volume output and set its maximum volume to 10 Ad a suitable block to represent the input flow rate (The slider shown below is no longer available). Numerical LED displays may then also be aded to display the input flow rate and head of water. Your model should now lok similar to the one show below. In the simulation parameters menu set the stop time to 100s and the maximum step size to 0.01seconds. The tank must not be filed more than 95% .b)Run the simulation and adjust the flow control manualy until equilibrium is achieved at maximum capacity.c)What is the flow rate and head in the tank?Marine Engineering Simulation and ModelingCoursework: Tank Level Closed Loop Control SystemIn this question combine the systems in Question No.2 and No. 3:a)Copy and paste the servo valve model into a new project.b)Select the dynamics and make it into a subsystem.c)Copy the tank level subsystem into the same project.d)Combine the two subsystems with other functions, so that with a mean input flow rate of 60 m3/s with standard deviation of 5 m3/s the tank is never filed more than 95%. Your system should resemble a typical fedback control scheme.e)Explain the nature of the input flow rate.f)Reduce the system a further layer (put it in a subsystem), and ad suitable gauges to display the valve position, input flow rate, and tank volume.g)Tune the system (se Question No.2) if necesary to give an ‘aceptable’ servo valve response.h)Explain the nature of the input flow rate and coment on the results.The uper layer of system should be similar to that shown below.本团队核心人员组成主要包括硅谷工程师、BAT一线工程师,精通德英语!我们主要业务范围是代做编程大作业、课程设计等等。我们的方向领域:window编程 数值算法 AI人工智能 金融统计 计量分析 大数据 网络编程 WEB编程 通讯编程 游戏编程多媒体linux 外挂编程 程序API图像处理 嵌入式/单片机 数据库编程 控制台 进程与线程 网络安全 汇编语言 硬件编程 软件设计 工程标准规等。其中代写编程、代写程序、代写留学生程序作业语言或工具包括但不限于以下范围:C/C++/C#代写Java代写IT代写Python代写辅导编程作业Matlab代写Haskell代写Processing代写Linux环境搭建Rust代写Data Structure Assginment 数据结构代写MIPS代写Machine Learning 作业 代写Oracle/SQL/PostgreSQL/Pig 数据库代写/代做/辅导Web开发、网站开发、网站作业ASP.NET网站开发Finance Insurace Statistics统计、回归、迭代Prolog代写Computer Computational method代做因为专业,所以值得信赖。如有需要,请加QQ:99515681 或邮箱:[email protected] 微信:codehelp
