Abstract

Vibration testing on telemetry system payload is needed to determine its resistance to vibration during operation. Vibration testing of telemetry system payloads requires a test fixture. Test fixture is used to transmit vibration from shaker to telemetry system payload. The payload of telemetry system to be tested is a tubular. The test fixture in this study was designed using SolidWorks software. The material used for manufacture of test fixture is aluminum. Aluminum material was chosen because it has good rigidity with a relatively light mass. Stiffness and mass properties affect to natural frequency value of test fixture, which must be greater than the frequency range of operating telemetry system. Data collection uses two accelerometers placed on test fixture. Sine sweep vibrations are given from 5 Hz to 2000 Hz with a constant amplitude of 1 g and a sweep rate of 1 octave/minute. The test produces three peaks that they are candidates as natural frequencies, i.e at a frequency of 1532 Hz with an amplitude of 2.898 g, a frequency of 1706 Hz with an amplitude of 6.582 g, and at a frequency of 1806 Hz with an amplitude of 6.472 g. From those three natural frequencies, the second natural frequency at 1706 Hz is the most critically because it has the largest response value.

Abstract

Efficiently managing academic information systems (AIS) is essential for educational institutions to provide reliable services to students and faculty. This research explores the integration of HAProxy load balancing and file synchronization techniques to optimize the performance of AIS. HAProxy is employed to distribute incoming requests across multiple backend servers, and the backend will call web service to access the data saved in the database to facilitate seamless data sharing and access. Additionally, file synchronization mechanisms are implemented to maintain consistency across scripts used in the backend system. The study conducts performance evaluations and benchmarks to assess the impact of HAProxy load balancing and file synchronization on AIS responsiveness and reliability. The results reveal significant system scalability and fault tolerance improvements, reducing downtime and enhancing user experience. This research contributes to optimizing academic information systems, enhancing their ability to handle increased loads, and ensuring the efficient delivery of educational services.
