Design, Synthesis and Analysis of loader bucket, boom and linkages for amphibious infantry combat vehicle.

Independent Researcher-Abhijit Kulkarni

  • Technical Paper
  • 2019-28-0124
To be published on 2019-10-11 by SAE International in United States
The paper discusses about the design synthesis and development of dozer bucket mechanism which will be a single unit to perform dozing and loading operation and will be connected to the amphibious infantry combat vehicle for various military activities such as construction of bridges, digging trenches, construction of roads, and clearing the area during landslides. Currently, separate unit for bulldozer for dozing operation and loader for loading operation are required. But the need was to develop a single unit which could perform both of these operations efficiently. Research and development efforts initiated to carry out synthesis of mechanism (Linkages and Boom) which will fulfil the above stated functional requirement and satisfy the geometrical constraints. The synthesis of mechanism is done with help of ‘CATIA’ software packages. The force calculation on various joints at the different position of mechanism has evaluated with the help of ’ADAMS’ software. The finite element analysis is done using software ’ANSYS’. The developed mechanism combines the dozing and loading operation and connected to the tracked vehicle. It also satisfied geometrical constraints…

JCB prepared to meet EU Stage V emissions

SAE Truck & Off-Highway Engineering: August 2019

Published 2019-08-01 by SAE International in United States

JCB is preparing to offer Stage V compliant engines across its equipment lines, with updates to its own engine range and changes to supplier models. Group director of engines Alan Tolley said that the company has preferred to tackle emissions within the combustion system, rather than simply adding aftertreatment to the exhaust system; however, for Stage V, diesel particulate filters (DPFs) and selective catalytic reduction (SCR) will become necessary.

Personnel Protection - Skid Steer Loaders

OPTC1, Personnel Protection (General)
  • Ground Vehicle Standard
  • J1388_201907
  • Current
Published 2019-07-03 by SAE International in United States

This SAE Standard is intended to provide personnel protection guidelines for skid steer loaders. This document is intended as a guide towards standard practice, but may be subject to frequent change to keep pace with experience and technical advances. This should be kept in mind when considering its use. This document provides performance criteria for newly manufactured loaders and it is not intended for in-service machines.

 

Hydraulic Excavator Operator Controls

MTC C5, Excavators
  • Ground Vehicle Standard
  • J1177_201906
  • Current
Published 2019-06-06 by SAE International in United States

This standard covers mobile hydraulic excavator controls and the specific arrangement and direction of motion for the primary controls. This standard applies to mobile hydraulic excavators as described in ISO 7135 - Earthmoving Machinery - Hydraulic excavators - Terminology and commercial specifications, and ISO 6165- Earthmoving Machinery - Basic Types - Vocabulary. Purpose This standard is intended as a guide for designing uniform two lever type operating controls for mobile hydraulic excavators, either wheel mounted or crawler mounted on independently reversible tracks.

Q&A

SAE Truck & Off-Highway Engineering: June 2019

Published 2019-06-01 by SAE International in United States

For years Volvo Construction Equipment has operated wheel loaders via remote control in underground mining operations, first for very dedicated tasks and more recently increasing the flexibility and scope of their operation. A recent test program with mining company Boliden examined both standard WiFi and a 4G+ communication system built with the help of Ericsson, on a machine located more than 400 m (1,300 ft) below ground. Though the program was deemed a great success by both companies and considered an important step on the pathway to truly autonomous machines, they agreed that a more robust communication system was necessary. Hello 5G.

Using a System Reliability Model to Optimize Maintenance Costs A Best Practices Guide

HM-1 Integrated Vehicle Health Management Committee
  • Aerospace Standard
  • JA6097_201905
  • Current
Published 2019-05-07 by SAE International in United States
SAE JA6097 (“Using a System Reliability Model to Optimize Maintenance”) shows how to determine which maintenance to perform on a system when that system requires corrective maintenance to achieve the lowest long-term operating cost. While this document may focus on applications to Jet Engines and Aircraft, this methodology could be applied to nearly any type of system. However, it would be most effective for systems that are tightly integrated, where a failure in any part of the system causes the entire system to go off-line, and the process of accessing a failed component can require additional maintenance on other unrelated components.

Diagnostic Communication with Road-Vehicles and Non-Road Mobile Machinery

Softing Automotive Electronics GmbH-Peter Subke
  • Book
  • R-474
Published 2019-03-01 by SAE International in United States
Diagnostic Communication with Road-Vehicles and Non-Road Mobile Machinery examines the communication between a diagnostic tester and E/E systems of road-vehicles and non-road mobile machinery such as agricultural machines and construction equipment. The title also contains the description of E/E systems (control units and in-vehicle networks), the communication protocols (e.g. OBD, J1939 and UDS on CAN / IP), and a glimpse into the near future covering remote, cloud-based diagnostics and cybersecurity threats.
