Safety and Crashworthiness Protective Measures in the Bus Industry

11/28/2012

Giuseppe Resta -   Business Development Manager, Global Automotive, Altair

 

Bus travel continues to be one of the safest modes of transportation. Global bus engineering trends focus upon quality and durability in bus design, since the typical service life of a motorcoach often exceeds 20 years and may reach 3 million km., depending on the country. Still, safety and crashworthiness remain essential elements in bus design with opportunity for improvement.  Too many passengers are affected by accidents, which drive the industry to push for progress in bus safety features.  Cross-country motorcoaches and school buses have been the subjects of significant attention and regulatory action, particularly in relation to rollover events.

The Challenge of Crashworthiness for Composites Cars

08/20/2012

guiseppe Giuseppe Resta -  Business Development Manager, Global Automotive

 

It doesn’t seem so long ago that passenger safety and vehicle crashworthiness were the battleground where automakers differentiated their products. Now, as many OEMs have created product development systems that rely on a CAE-driven strategy to deliver excellent passive safety performance, it appears to have taken a backseat to miles-per-gallon. Almost every car commercial touts greater fuel efficiency and seeks to validate the manufacturer’s environmental credentials.

Both safety and gas mileage advances have been pushed by regulation and pulled by consumer demand. Now that the United States has set the 54.5 mpg Corporate Average Fuel Efficiency (CAFE) standard for 2025 and lower CO2 emissions have been mandated in Europe, we are entering a new era of increased challenge that could lead to significant change in the way cars are designed and constructed. OEMs and suppliers are reviewing every component and considering the technologies available to meet these new demanding standards, including investment in engineered plastic and carbon-fiber-reinforced plastics (CFRP) that offer high stiffness-to-weight and strength-to-weight ratios.

CAD to Crash in 24 Hours

08/02/2010

By Darius Fadanelli
Director – Customer Support

CAD2Crash24

Introduction

Engineering analysts are continually being asked to get more done in less time. In addition, they are overwhelmed with learning to use many individual tools that claim the ability to perform a specific task or component of a job. This further drives the need for one integrated suite of tools that can use the same licensing system to complete a process from start to finish. To address this need, Altair has implemented many complete processes that are flexible and configurable with the Altair HyperWorks Suite.
