MP3672-Kinetic analysis & Engineering Simulation - Engineering Assignment Help

Assignment Task

Task

1 Introduction
The principles of an Industry Standard Kinetic Simulation Package have been covered in the module lecture material. You are required to produce a simulation of a system Within the SimMultibody systems. The Matlab system should be fully modelled and unique to you and should include results. The scenario should be complex enough to allow you to critically evaluate SimMultibody as an engineering simulation tool.

2 The key skills developed in this assignment are:
• Communication – report writing skills, presentation skills
• Use IT effectively – simulation software and word-processed report
• Independent learning – research motion analysis
• Time management – manage class contact, independent working effectively

3 Module Learning Outcomes addressed in this assignment:
• Use and evaluate industry standard software
• Assess the need for relevant modelling systems
• Analyse how certain factors are affecting the accuracy of a simulation
• Use engineering software effectively and compare exact solutions with simulation generated solution and evaluate differences and characteristics
• Demonstrate effective research and report writing skills

Model 1: Piston assembly
A motorcycle racing team using the Aprilia 250 V-Twin have approached to discuss the idea of piston assembly configuration improvements, they have provided the STEP files for consideration. They have noted that they are running Nickel cylinder with a mild steel piston which they confirm through testing give a coefficient of friction 0.000178. They have requested an analysis of the effects of cylinder angle in a range of 10 -180 degrees.

Model 2: Suspension
A formula one RC race team has approached and informed us that they are developing a new race car. They have confirmed that they do not mind the assumption that the weight of the main body can bethe same as normal 5Kg. They have delivered us with an STEP file that denotes all positions of the suspension, as they have not detail the materials used for the assembly it is assumed we can assign our own sensible equivalent. The reason they have come to use is they are requesting spring damper values that are set to critical damping (a bump and a bit).

Modelling Tasks:
1. Simplify the provided STEP model to establish a working model in SimMultibody.
2. Using present theory generate a spring damper verification of the model to indicate you works validity.
3. Make design changes to the present configuration and report recommendations for the requirements.

Model 3: Arm Exoskeleton
The company Mawashi are working on a new exoskeleton, this has been designed to aid the user in raising there bicep from straight to a 90? position. They are extremely worried that the arm should not be moving to fast and as such would like the operation to be completed in a time range between 3 - 4 seconds. They are proposing to use a (ti-6al-4v) metal for the parts and intend to use a journal bearing, as such they have agreed an operational damping function of 0.001 - 0.01 to take into consideration the life of the system. The user will need to be able to handle 500 N of force. They have provided a model pack with this, within it would will find the original Solidworks model to give to reference and also all of the STEP files for the analysis of the exoskeleton. The one thing that they dont know is what motor should be used for the job? They are suggesting that a servo motor could be used hence the model having a servo block. For this work we can presume weights to be of the average UK male.

Modelling Tasks:
1. Simplify the provided STEP model to establish a working model in SimMultibody.
2. Using present theory generate verification of the model to indicate you works validity.
3. Make design implementations to the present configuration and report recommendations for the requirements.

Model 4: Manufacturing robot arm
Fanuc have approached and are interested in developing a new robotic arm for a propeller shaft production line. They have developed there an arm however, are struggling to find an ideal operation value for their motors for each joint of the arm. The main base of the arm will be made from 1023 carbon steel alloy and all other components will be made from 5052 aluminium alloy. There load baring capacity of the arm will be set to 2000 kg. There notes also say that they expect any lubricated factors and friction to equate to a 0.001 ratio. They also would prefer that the arm only moves between 2 mm/s. They have provided the assembly as a single STEP format.
Thus they would like you to find the operational idea values for this requirement. The process cycle they have asked to be created has been given in the terms of end of the arm relative to the base of the robot, radius of the arm to the axis through the base and angle.

Modelling Tasks:
1. Simplify the provided STEP model to establish a working model in SimMultibody.
2. Using present theory generate a spring damper validation of the model to indicate you works validity.
3. Make design implementations to the present configuration and report recommendations for the requirements.

Model 5: your company
Some of you are presently working at engineering companies, you can choose an example from your work place and the material MUST be a true example. Your system must be dynamic, for ease of the simulation lubricated factors and friction to equate to a 0.001 ratio. BEFORE EXECTUTING YOU MUST HAVE CLEARENCE FROM YOUR LECTUER FIRST.

Modelling Tasks:
1. Establish a working model in SimMultibody.
2. Using present theory generate a balancing validation of the model to indicate you works validity.
3. Make design changes to the present configuration and report recommendations for improvements.
