Automated Pneumatic Braking and Bumper System

Automobiles have been used to move human beings or things and the automobile technology has been developed within the last few years. The traffic accidents are increasing as automobile production has been increasing. The number of casualties during the vehicle accidents is very large as compared to the other causes of death. It is important to prevent accidents and to protect the driver and pedestrian when accidents occur. Though there are different causes for these accidents but proper technology of braking system and technology to reduce the damage during accident (such as pneumatic bumper system) can be effective on the accident rates. Therefore, pre-crashing system is demanded. Automotive safety has gained an increasing amount of interest from the general public, governments, and the car industry. The pre-crash system is to prevent accidents on roads with poor visibility by using sensor network to find invisible vehicles, which are to be detected by autonomous on-vehicle sensors. The pre-crashing system is processing the sensor data and controlling the vehicle to prevent accidents and accidents caused by careless driving. The pneumatic system is simple and easy in operation and hence can be used in automation industry.

Design & Fabrication of Intelligent Bumper and Braking System

In today’s world automation is increasing day by day which includes Pneumatic technology, it had gained tremendous importance from old age & coal mining to modern machines like heavy machinery’s & even in space robot’s. to surf along with the study or market research one should must have knowledge in pneumatic system. The main course of this project is to study on pneumatics’ and to relate the topic in the project. In that case we designed and fabricated Intelligent electronically controlled automotive bumper activation called “PNEUMATIC BUMPER & BRAKING SYSTEM”. This system has a ARDUINO UNO as a micro controller, IR transmitter & Receiver circuit & Pneumatic actuators used as braking & bumper system. Now a day’s accident is a huge problem especially in INDIA due to improper construction of road and tracks. To overcome this problem this project helps in minimizing the accidents & greatest damage to the person if accident takes place.

Energy absorption capability of origami automobile bumper system

The crashworthiness of an automobile bumper plays a vital role in overall vehicle safety. Energy absorption efficiency, as well as predictable and stable performance, are the most demanding features in the design of the bumper system. To this end, this paper presents a series of innovative bumper designs using built-in origami patterns. Also, we outline a numerical framework for evaluating the energy absorption performance of a bumper when subjected to an impact loading. Comparative analyses on full frontal and 40% offset frontal impact tests are conducted numerically for both low and high-speed scenarios. It is found that the designed failure modes are successfully triggered and followed during the collision process for the combined origami beam-origami crash box design. Most importantly, this optimal design could absorb 31.5% more energy than the conventional bumper.
