Abstract

The design & development of automated chair is done in the project for the Excavator machine to ensure the comfort of the rider ensured for any angle of work being carried out by the excavator. The various components like the chair, support rod, rod end eye bearing, the control valves for the flow, pressure and direction, hose pipe and hydraulic cylinder are used to make the model of the automatic chair. The various electronic components like the proximity sensors, relays and SMPS are utilized to control and regulate the incline and decline of the chair as per the machine’s inclination so that horizontal position of the chair can be attained. The part designing and the assembly of all components are conducted in CATIA software. The circuit diagram for the proximity sensor is also made. The model is fabricated using the tools and equipment like the gas cutter, grinding machine, bending machine etc. The prepared model is tested for the incline and decline of the chair at 20˚ angle using the real-life working parameter of the machine. From the test the chair is observed to properly attain the horizontal position along with actuation of hydraulic cylinder by making sure that operator’s centre of gravity is maintained to ensure the comfort of rider.

Highlights

  • The seat in any automobile is an important part that allows the rider to be comfortable for controlling the vehicle as per the travelling condition

  • The various ergonomic approach is carried out for researching in the field of the seat comfort that can be attained by the optimization in the design of the chair and its support structure so that the rider is prevented from any discomfort while operating the vehicle

  • The final conclusion was derived that the difference in the chair design consisted of the greatest effect on the interface pressure of the seat pan [3]

Summary

INTRODUCTION

The seat in any automobile is an important part that allows the rider to be comfortable for controlling the vehicle as per the travelling condition. The comfort level provided by the seat is a huge concern for the drivers/operators who are subjected to a high duration of seating to regulate and control the vehicle. The longer period of being in seating position of the driver might result in various physical and mental fatigues on driver which might lead to the fatal accidents of the vehicle. The various ergonomic approach is carried out for researching in the field of the seat comfort that can be attained by the optimization in the design of the chair and its support structure so that the rider is prevented from any discomfort while operating the vehicle
