To achieve the project objective, the test rig structure must be design and suitable for place the archery testing apparatus. We need to develop tools that can test the efficiency in archery equipment. The arrows were made of pine and consisted of a main shaft and about 15–20 centimeter (6–8 inches) long fore shaft with a flint point. This led the commercial development of new forms of bow including the modern recurve and compound bow. These modern forms are now dominant in modern Western archery while traditional bows are in a minority.
In the 1980s, the skills of traditional archery were revived by American enthusiasts, and combined with the new scientific understanding. As we know, test rig machine that is use in industrial is very expensive in the market and some way need to be build by engine performance analysis based on functionality of power supply. Hence, our test rig been replaced with modern one where its materials very cheap and easy to find in market. Some sketches software had used like Solidworks to draft out the shape of our archery test rig.
Materials selection also included in this designed process. Variable height and angle will be given at various speed by the stretch of bow’s string to see whether performance of archery will decrease or increase. Here, we can analyze at which arrow speed is the optimum of performance from this small mechanical. So, some losses like power and fuel can be decrease.

All this information is important before furthering to the analysis and study later. ii. BASIC CONCEPT OF TEST RIG PERFORMANCE Archery test rig performance characteristics are convenient graphical presentation of archery test rig performance. They are constructed from the data obtained during actual test runs of the test rig and are particularly useful in comparing the performance of one bow and arrow with that of another. In this section some of the important performance characteristics of the test rig are discussed.
It is to be noted that there is a certain speed, within the speed range of particular length of string stretched, at which force applied that is the length of string stretched will be the maximum. At this point, the maximum speed can therefore be exerted on the bow. For all practical purpose, the spring constant or bow capacity to do work also will maximum at this point. As the speed of the arrow is increased above this speed the quantity of the indicated time will decrease. However, the work output of the test rig increases with the speed due to longer length is executed per spring stretched.
It should be note that the external air resistance will continue to increase with increased arrow speed until some point is reached where the air resistance almost can be negligible due to rapid movement of speed per second. Test rig are so designed that the maximum speed applied point is reached within various angle and height of the test rig. Increase in speed applied means that the increased targeting can be added per unit time increasing the work output. iii. FOUNDATION OF TEST RIG PERFORMANCE TESTING
Test rig performance is really a relative term. Normally it is represented by typical characteristic curves which are functions of testing at some variable of some situation and for our case is archery game. The term performance usually means how well a system designed is doing its job in relation to the input energy or how effectively it is provides useful work in relation to some other comparable industrial test rig machines. Most of the testing of test rig for their performance characteristics takes place under laboratory condition.

The test rig is connected to a mechanical-based devices such as jack, spring and usual lift up mechanism by lifting the height of the steel in particular joint part. However, the performance characteristics of work, speed versus string stretched, degree of angle, height of devices of bow and arrow are recorded. There are so many types of industrial test rig used but using automation to quickly perform measurements and evaluate the test results. Principle that we used is mainly just simple mechanism that involve physics law and design it using Solidworks software.
Our design of test rig operation is to allow the casing the arrow to swing freely with various variables that we figure out in this evaluation. The reaction string stretched various length, L, which is exactly equivalent to the speed measured on a level speed per time, ? , from the line section of the bow there are angle elevated, ?. The height of the test rig also can be organized. This restrains the attach casing of bow’s holder from revolving, or the speed and work would not be affected. Then, there are several factors that must considered in evaluating the performance of the test rig.
Most of them are maximum work or speed available at each length string stretched within the useful particular of variable. iv. THE IMPORTANCE OF TEST RIG PERFORMANCE TESTING Today the most common power source is the well-known in industrial test rig machine. This type of test rig machine has been the choice due to efficient and accurate result in testing equipment for an example. For out invention may become natural choice due to low cost and portable properties. The portable characteristics shown may be easy because does not any electrical supply due to mechanical works only use in our test rig and easy to moves by just man-power.
Industrial test rig machine as we know it today is not able to comply with future emission demands due to its massive cost and power used not very appropriate for some minority field. However, in the future manufactures must come up with new cost-efficient test rig technologies that still deliver the same or improved performance for customer satisfaction. III. MARKET SURVEY Test rig is an apparatus used for assessing the performance of a piece of mechanical or electrical equipment. In our case is to assessing the performance of archery’s equipment that is the bow and arrow.

CHAPTER 2 METHODOLOGY I. PLAN TO DESIGN THE PRODUCT The actual construction was very similar to the preliminary design. The end test rig, when fully assembled.
The mechanism is the height can be change by requirement of user. There are two blocks that are used for joints of supporting another holder of the arrow as well as the traction rope length u bow in the spring in the valve use to draw and release the bow string when want shoot. The angle of the bow can also be changed by using the ball and socket as our knees. There is another part that supports the ball and socket is attached to one of the blocks that support the horizontal position of the bow string pullers. The height of this test rig can be changed under by jack at the bottom part of the test rig.
Jack with rotor will be rolled over by man-power only and it will lift the top part of the test rig. In the preliminary design two supporter were described below in our drawing, master spring switch length and a socket and ball joint in that can joint the bow with the spring switch length . In the actual design, these 2 parts were combined into a single part switch that also has a pull/push holder- feature. Many features were added to aid in the setup and tear down of the test stand. The upper part and the lower part both have straight plane that come in contact with the base, and at each of these points there is a single ? n bolt. At the base of each upper 2 block supporter and after the jack assembly there are plane quick that can be disconnects which allow them to be separated from the rest of the structure. The electrical connection is not exist at all in this test rig. All these features allow for the test stand to be assembled and disassembled in approximately 10 minutes. Actual Test Rig Picture shown below: Door testing for its joints and locking setup Testing. Small testing setup installed on seats for complete cycle testing of all for doors of the car.
Calculation of door closing and opening speed with the accurate door displacement by servomotor. Reports and data can be visualized on remote PC outside Car. The torsion fatigue test rig (TFTR) was constructed to experimentally characterize the fatigue behaviour of materials that fail due to oscillating shear stresses. It consists of a base, hydraulic rotary actuator, and torque cell. Given the horizontal configuration of the rig, light weight mechanical adapters were designed to interface with the torsion bar specimens to minimize the interference of bending moments on the tests results.
The adapters are essentially custom designed collet fixtures with base flanges for mounting, and they use off-the-shelf collets and clamping nuts to retain the specimen and transmit torque. Tests are generally carried out in torque controlled mode and the prescribed torque levels/amplitudes are controlled through commercial software. In this case of our test rig, the speed can be evaluated by the length of string stretched in such angle specified. The height also can be determined in such way by jack illustrated mechanism.
Our design of test rig operation is to allow the casing the arrow to swing freely with various variables that we figure out in this evaluation. The reaction string stretched various length, L, which is exactly equivalent to the speed measured on a level speed per time, ? , from the line section of the bow there are angle elevated, ?. The height of the test rig also can be organized. This restrains the attach casing of bow’s holder from revolving, or the speed and work would not be affected. Then, there are several factors that must considered in evaluating the performance of the test rig.
