Systematic Way for Problem Identification of Car Braking System by Using TRIZ

This study aims to determine whether the supervision activities to improve teachers' teaching skills in SMPNegeri 1 Kampar Timur, Kampar. Based on background description, problem identification and problemrestriction, the focus of this research is related to supervision activities to improve teachers' teaching abilities inSMP Negeri 1 Kampar Timur, Kampar. The School Action Research is conducted only at SMP Negeri 1 KamparTimur Kampar District. In one supervision of the researcher himself. The type of this research is School ActionResearch (PTS) located in SMP Negeri 1 Kampar Timur, Kampar, which is aimed at teachers. The main reasonis from the results of observation and information from teachers, that pedagogic competence of teachers is stillclassified as less. The sample in this study is all teachers in SMP Negeri 1 Kampar Timur, Kampar amounted to55 people. From the description of data processing and discussion, it can be concluded that the pedagogiccompetence of teachers obtained in the first cycle of 60% with good category and on the second cycle increasedto 80% with good category. This means that supervision activities can improve teachers' teaching skills in SMPNegeri 1 Kampar Timur, Kampar is said to succeed.

Fill Level

Road safety depends on several factors associated with the vehicle, to the infrastructure, as well as to the environment and experience of vehicle drivers. Concerning the vehicle factors influencing the safety level of an infrastructure, it has been shown that the dynamic interaction between the carried liquid cargo and the vehicle influences the operational safety limits of the vehicle. A combination of vehicle and infrastructure factors converge when a vehicle carrying liquid cargo at a partial fill level performs a braking maneuver along a curved road segment. Such a maneuver involves both longitudinal and lateral load transfers that potentially affect both the braking efficiency and the lateral stability of the vehicle. In this paper, a series of models are set together to simulate the effects of a sloshing cargo on the braking efficiency and load transfer rate of a partially filled road tanker. The model assumes the superposition of the roll and pitch independent responses, while the vehicle is equipped with Anti-lock braking System brakes (ABS) in the four wheels. Results suggest that cargo sloshing can affect the performance of the vehicle on the order of 2% to 9%, as a function of the performance measure considered. A dedicated ABS system could be considered to cope with such diminished performance.

Convection Cooling

A heightened awareness of the importance of natural convective cooling as a driving factor in design and thermal management of aircraft braking systems has emerged in recent years. As a result, increased attention is being devoted to understanding the buoyancy-driven flow and heat transfer occurring within the complex air passageways formed by the wheel and brake components, including the interaction of the internal and external flow fields. Through application of contemporary computational methods in conjunction with thorough experimentation, robust numerical simulations of these three-dimensional processes have been developed and validated. This has provided insight into the fundamental physical mechanisms underlying the flow and yielded the tools necessary for efficient optimization of the cooling process to improve overall thermal performance. In the present work, a brief overview of aircraft brake thermal considerations and formulation of the convection cooling problem are provided. This is followed by a review of studies of natural convection within closed and open-ended annuli and the closely related investigation of inboard and outboard subdomains of the braking system. Relevant studies of natural convection in open rectangular cavities are also discussed. Both experimental and numerical results obtained to date are addressed, with emphasis given to the characteristics of the flow field and the effects of changes in geometric parameters on flow and heat transfer. Findings of a concurrent numerical and experimental investigation of natural convection within the wheel and brake assembly are presented. These results provide, for the first time, a description of the three-dimensional aircraft braking system cooling flow field.
