This paper deals with a numerical approach for improving the mechanical properties of a safety belt anchor. The goal is to optimise the component shape and its manufacturing process by using a multi-objective genetic algorithm (NSGA-2). This kind of automotive component is typically manufactured in three stages: blanking, rounding of the edges by punching and finally bending (90°). The numerical model is linked to the genetic algorithm (GA) in order to optimise design, material and process parameters. This is implemented by using ABAQUS© and CATIA script files. The material behaviour is modelled using a specific Lemaitre material damage formulation implemented in ABAQUS©. A global optimisation is finally performed in order to improve the ultimate unbending load and the volume of the safety part. This work has two major areas of innovation: a) the improvement of the genetic algorithm NSGA-2; b) the development of an integrated numerical procedure including 'computer aided design' and 'mechanical finite element simulation' controlled by the genetic algorithm.

The Case for an Integrated Quality Management and EHS System
By bringing together quality management and environmental health and safety (EHS), the integrated QEHS system is a powerful proposition that delivers a real return on investment over relatively short timescalesAs increasing numbers of organizations embrace the benefits of enterprise quality management systems, it’s only natural to consider other opportunities for greater automation of key functions and processes. One obvious contender is the organization’s environmental, health and safety (EHS)...
4 Tips for Improving Employee Safety with Industrial Hygiene
Industrial hygiene prepares organizations for a number of environmental stressors—chemical, physical and biological—that may impair the well-being of employees or community members. Having good industrial hygiene practices plays an important role in improving employee safety and developing an organization-wide safety culture. Here are 4 tips for leveraging Environmental Health and Safety (EHS) management tools to improve employee safety through industrial hygiene. 1. Use Risk Tools to Gather and...
Pipeline valve actuators for safety-related duties
Sectors: Oil & Gas Category: Failsafe Valve Actuation Products: HPG, GO, Electro-Hydraulic (SI) Introduction Pipelines present a number of operational requirements demanding specialised actuation solutions. These include actuation of valves in remote areas, where mains power sources are not available, and actuators to provide vital failsafe and safety shutdown duties, which are often in remote locations.For 60 years Rotork has manufactured electric and fluid power actuators for pipeline flow control in...
Safety vs. Environment Protection: Study Discovers Increasing Salt Levels in Lakes
A recent study published by the US-American National Academy of Sciences revealed an increasing salt amount in form of chloride in rural and urban freshwater lakes around the American continent. The scientists believe, that mainly road salt distributed on icy roadways is to blame. Increasing salt levels threaten eco systems Road de-icing salt is blamed for rising salt levels in freshwater lakes. This was uncovered by a study of the National Academy of Sciences carried out for the last one and a half year. In...
Case study - Sherritt: Using msdsBinders to increase safety and reduce effort
IntroductionSherritt is the largest coal producer in Canada and the largest independent energy producer in Cuba. The company licenses its proprietary technologies and provides metallurgical services to mining and refining operations worldwide.SituationBefore msdsBinders the office was full of dusty old binders that sat in the corner and were rarely accessed. Most MSDSs were outdated. Paper-based MSDS management was a huge challenge.Sherritt needed a time efficient method to manage chemical activity and a significan...
