To investigate the rotation vibration dynamics of the pulleys and the tension arms, and to estimate the vibrations of the belts and the slip ratio between the belt and the pulleys in the engine front-end accessory drive systems, a systematic modelling and analytical method is proposed for engine front-end accessory drive systems; this can be used for modelling engine front-end accessory drive systems with different layouts and different numbers of tensioners, including automatic and fixed tensioners. In the modelling, the rotational pulleys are classified as fixed-axis pulleys and moveable-axis pulleys (such as the pulley in the tensioner). Moreover, the belt spans are classified as the belt spans between the two fixed pulleys, and the belt spans adjacent to the pulley of a tensioner. The equations of motion for each type of pulley and the tension calculation equations for each type of belt span are developed. In this way, the equations of motion for all the pulleys and the tensioner arms can be obtained easily, irrespective of the layout of the tensioners. To obtain the dynamic rotational vibration responses of an engine front-end accessory drive system by the conventional Runge–Kutta method, high-efficiency algorithms or methods are also proposed for calculating the tangent-point coordinates between a belt and the adjacent pulleys and the belt length of the contact arc on one pulley. The proposed modelling and analysis methods are validated by modelling different layouts of the engine front-end accessory drive systems with different types and numbers of tensioners, and also by comparisons between the calculated dynamic vibration responses of the pulleys and the belts and the real experimental data.

Abstract This paper discusses the design and conceptualization of a novel robotic mechanism to clean the trench drains. It describes a different approach for drain cleaning with lesser human intervention and more safety to personnel involved. The robot is designed and built to be 4 inches in width and operate entirely within the limited space inside the drain. To achieve a wholesome cleaning process, the entire robot is modular in design and consists of a drive system, a suction tube and a cutting arm assembly with metal brushes installed onto it. The bidirectional drive system enables the robot to move through drain segments repeatedly for optimal performance. The purpose of the cutting arm assembly is to aid the removal of dirt from the drain. In order to improve the robot performance, two prototypes were designed and built. The overall design and modularity of both robot prototypes will be discussed in detail in the paper.

Serpentine Belt

This paper presents the effects of lateral misalignment of sheaves, on the transverse span displacements of a serpentine belt drive system that contains a driving sheave, a driven sheave, a belt, and a dynamic tensioner. This defect gives rise to dangerous operating conditions for the system. A hybrid discrete—continuous model is adopted, in which the coupling between the discrete variables describing the rotational motion of the three sheaves and the tensioner arm and the continuous variables describing the transverse motion of the belt spans is taken into account. An analytical method based on the perturbation method is used to determine the explicit expressions of the transverse span displacements and permits the study of the effects of design variables on the dynamic behaviour of the system in the presence of the defect described earlier.

For sake of researching PMSM nonlinear parameter of a drive system, a load test is designed to get input-output property under the condition of different load. The main parameters of machine are estimated by applying predicting-error algorithm, then the data sets are used to train four neural network parameter models. To validate the model simulation method is used to study the speed and torque response. The results show that the way can optimize parameters of machine effectively and can be utilized for on-line parameter identification and electric drives.
