COURSE NOTES AND TUTORIAL HANDOUTS BY AIP V.KOSSE WHICH ARE AVAILABLE FROM THE BLACKBOARD SITE FOR ENBZ15 UNIT ARE PERMITTED (THIS MATERIAL MAY BE ANNOTATED) INSTRUCTIONS TO STUDENTS: Students are prohibited from having mobile phones or any other device capabie of communicating information (either verbal or written) in their possession during the examination NOTES MAY BE MADE QNLI ON THE EXAMINATION PAPER DURING PERUSAL TIME ALL THREE (3) QUESTIONS ARE TO BE ATTEMPTED ALL ANSWERS MUST BE WRITTEN BY A BALL PEN (BLACK OR DARK BLUE COLOUR) ANSWERS WRITTEN IN PENCIL WILL NOT BE ACCEPTED AND WILL BE MARKED AS “ZERO” RESULT PENCIL CAN ONLY BE USED FOR SKETCHING AND DRAWING DIAGRAMS MARKS FOR EACH QUESTION ARE AS INDICATED Queensland University of Technology am Gardens Point at" Kelvin Grove GUT Carseidine QUESTION 1 Using TRIZ tools solve the following problem. Modern submarines are equipped with a range of weapons including torpedos. The torpedo carries the warhead, which could be high explosive or nuclear. To make torpedos effective they have to move through water at as high speed as possible. The speed is limited by the water resistance (drag). Engineers exhausted all possible design solutions to maximise the torpedo speed, which is still relatively low. Significant increase of the engine power does not give a notable increase of speed because the drag is proportional to the velocity squared. It looks like there is no way to significantly increase the speed of torpedos. This is not true. Recently in Russia a new type of torpedo was developed that can move through water at a speed of up to four to five times that of conventional torpedos. How is it possible? Using TRlZ tools come up with alternative concepts of now to increase the speed of torpedo by a factor of tour at least. Explain step~by—step how you develop the solutions. [20 marks] QUESTION 2 Carry out a functional analysis of a product. Carry out a functional analysis of the reconfigurable clamp shown in Fig. 1 below. It has two jaws — one fixed and another one movable. The release lever is used to undo the clamp or open it up. When the fixing clip is loosened one jaw can be detached and put at the opposite end of the rail. In this case the clamp can apply clamping force inside w cut. Stationary jaw Clamping outside-in Clamp with detached Jaw Fixing clip Clamping inside-out Fig. 1 Reconfigurable clamp EN13215T1.072 cont/... identify the basic and secondary functions (if any). identify components and their functions. Develop a functional tree up to the second level (or the third level if necessary). Assign significance (weight) to each function. Calculate general and partial coefficients of significance. Plot functional diagram sorting functions in descending order. [15 marks] QUESTION 3 Pinion-shaft assembly. A shafi; assembly is shown in Fig. 2 below. It transmits 2.1 kW of power at 960 r.p.rn. A pinion with 21 spur teeth has module 3mm. The shaft rests on two bearings. The radial force Fr lies in the horizontal plane and the tangential force Ft acts in the vertical plane. Torque T is transmitted from a free end of the shaft through a key joint between the shaft end and a coupling (not shown). Assume the endurance limit for the shaft material FR 2 360 MPa, and the safety factor S; = 2.4. Fig. 2 Shaft assembly For the given data determine the following: (a) Pitch circle diameter for the pinion, torque on the shaft, tangential and radial forces on the pinion. (4 marks) (b) Support reactions in the vertical and in the horizontal planes. (5 marks) (0) Plot shear force Vv and bending moment MV diagrams for the vertical plane. (8 marks) (d) Plot shear force Vh and bending moment Mh diagrams for the horizontal plane. (8 marks) (e) Plot twisting moment T diagram. (3 marks) (f) Determine equivalent bending moment M e at different sections of the shaft as M e : [(Mv) 2 + (M..) 2] (6 marks) (g) Identify the critical section on the shaft. (4 marks) ENBZ lSTl .072 Contl. .. (1‘!) Determine the shaft diameter D for the critical section and assume preliminary diameters for other shaft shoulders (make a sketch). (8 marks) Use the following formula: D3 Z (104'Sf/ FR)-Ks-K-Xi(Me 2 + T2) (mm3) Where FR is in MPa, MB and T in N-m. Assume the stress-raising factor K = 1.6, and the size factor KS 2 1.1 (j) Select bearings (use tables attached). Consider possible kinds of bearings that can be used and recommend the most suitable for this case. Assume the bearing life for 8-hour shift use in general industry. (7 marks) 0) Using the bearing dimensions finalise the shaft diameters and make a sketch giving diametral and linear dimensions. Remember to consult the metric table of preferred numbers. (6 marks) (k) Suggest suitable fit for the joint of the pinion with the shaft or the coupling with the shaft. Take values of deviations from tables provided and calculate clearances (interferences). Make a sketch of the fit showing tolerance zones and relevant parameters (dimensions, tolerances, deviations).
