Dynamic Behaviour Analysis of Single Stage Planetary Gearbox Under Non-Stationary Operations Using Experimental Test Rig

This paper presents an analysis of the failure modes during power transmission of a new type of one-way clutch called an expansible-band clutch. The new clutch is made from thermoplastic materials and an experimental test rig has been used to test two material combinations to failure. The experimental results are compared with predictions obtained from empirical formulae. The differences in the two sets of results are used to make conclusions about the failure processes.

The need to devise a low-speed balancing method for balancing high-speed rotors was recognized and addressed. In this paper, a scheme that combines both the influence coefficients and modal balancing techniques is presented. The scheme is developed for low-speed balancing of high-speed rotors, and relies on knowledge of the modal characteristics of the rotor. The conditions for applicability of the method were stated in the light of the experientially estimated rotor deflection mode shapes. An experimental test rig of a flexible rotor was constructed to verify the applicability and reliability of the low-speed balancing scheme.

The operation of pumps within a pumping station can be controlled by the Pressure Set Point (PSP) value compared to the reading of a pressure sensor placed either at the exit of the pumping station, on the main discharge pipe (classical PSP method), or at a critical/monitoring point within the water distribution network (termed further as remote-control PSP method). We designed and built an experimental test rig, allowing to study both control methods, in the attempt to check the advantage of the remote-control PSP method, with respect to the classical PSP method, since governing equations show that they are equivalent. The design relies on the theoretical approach and numerical results presented within this paper.

With the introduction of clutch-by-wire technology, electro-mechanical Automated Manual Transmission (AMT) has comes into existence. This leads the Drivetrain Research Group, Universiti Teknologi Malaysia to design and developed an indigenous drive-by-wire transmission for the future; which is the electro-mechanical dual acting pulley (EMDAP) continuously variable transmission (CVT). The group then designed and developed an indigenous drive-by-wire clutch, i.e. the electro-mechanical friction clutch (EMFC) to be integrated with the EMDAP CVT. However, to effectively electro-mechanically control the friction clutch, the relationship between motor current and clutch torque and normal force need to be fundamentally studied and established. The purpose of this paper is to set-up an experimental test rig to study electro-mechanical friction clutch actuator behavior and evaluate the correlation between the DC motor current, clutch torque and normal force of the friction clutch. Results from the correlation study will allow researchers not only to measure but also to later control the clutch clamping force using current sensor which relatively would be much simpler and less expensive than using force sensor.

Experimental Test Rig

Due to its excellent performances, the combined diesel and diesel (CODAD) propulsion plant is widely applied in modern medium-sized marine vessels. An experimental test rig of marine CODAD propulsion plant is built in the laboratory so that characteristics of the CODAD propulsion plant can be investigated in detail. Modeling of the CODAD test rig is presented at first in the paper. Validity of the model is proved with the experimental data. In order that an optimized merging process of the test rig can be accessed, a simulation analysis based on the model is carried out to choose rational engaging parameters of the clutches.
