Abstract

A water resource is an important element in the contemporary society life.  In global world water loss or water leaking can vary between 10% to 40% of total water volume produced.  A traditional method such as visual inspection can be operates but that method required a long time. The objectives of the research to identify the occurrence of leaks and know its exact location in the pipeline by using specific method which are acoustic leak detection method and transient method. An EEMD method will be applied as the analysis method to collect and analyses the data. Based on the experimental results that the EEMD analysis predict satisfactorily the location in MDPE pipeline as it can detect and locate the leak up to error of 4.09% and 0.61%. The EEMD method had the best perform and already produce an acceptable result.

Abstract

The research applies a skyhook-PID control method for an active suspension system. The control strategy has three feedback control loops. They are the innermost loop for the force tracking of the pneumatic actuator, the intermediate loops applying skyhook strategy for the elimination of the disturbances, and the outermost loop using PID controller for the determination of the desired force. Some experiments were carried out on a physical test rig with a hardware-in-the-loops feature. The performance of the proposed control method was evaluated and benchmarked to examine the effectiveness of the system in suppressing the disturbance effect of the suspension system. It was found that the experimental results demonstrate the superiority of the active suspension system with Skyhook-PID scheme compared to the PID and passive suspension systems.

Abstract

Ride comfort in vehicle transportation is quite complex, and it depends on various dynamic performance criteria and subjective perception from the car passengers. Vibration discomfort from various factors such as vehicle conditions, the speed of the vehicle, road surface condition, vehicle load, and operating condition can lead to poor ride comfort. Driver seat will be the main part of a car that needed to get a dynamic comfort. Comfort and safety are major factors that need to be considered. To ensure the safety for passenger, the driver must feel comfortable while driving. The objective of this project is to analyze the vibration at the seat of a Proton Wira at different speeds, different loads and different road surfaces. In this project, use six different speeds. Vibration data from two types of road and three different loads are collected using two accelerometers sensor that place on driver seat and seat frame. The rough surface will cause a car to generate more vibration. The results for frequency and time responses show that the vibration increases at the dirt road.
