Improved Engineering Productivity Through Use of Engineering Lifecycle Management Software

With CAE driving the design process at Ashok Leyland, the types of simulations performed as part of the vehicle development process is growing rapidly. Multiple simulation tools are required to address each of the different domains involved in vehicle development. Each tool requires a fairly complex process in which the user develops a model, inputs various engineering data, performs an analysis, reviews the results and authors a report to support design decisions. Ashok Leyland previously automated some of these steps for a few simulation tools using macros and scripts, but these point solutions were difficult to ensure the usage and maintain. The previous process relied upon the skills of the individual analysts writing the scripts. These automations were not always shared, versioned or used consistently among engineering groups, resulting in inconsistent results from one analyst to another and lacked traceability. The lack of a common simulation structure meant that it was difficult to locate the results and understand the reasons for previous decisions, so work often had to be duplicated.


Simulating Brake Squeal Noise

Brake squeal is one of the most challenging problems that car manufacturers have today. It occurs as a result of the vibration of the brake components such as brake disc and brake pads and therefore it disturbs the driver and passengers. Furthermore, because of its complex nature it is hard to completely understand the causes …


Multidisciplinary Solutions For Brake Squeal

Although engineers have started to use simulation software to test brake squeal, its complex nature usually requires more than one different software and discipline. This makes it difficult to transfer data from one software to another and to work in different environments. To address complex brake squeal in one environment, multidisciplinary solutions (MD) can be used. …


Composites in the Automotive Industry: Forum and Workshop October

Some of the most significant challenges facing the automotive industry include raw material cost, light-weighting and achieving mass production. These are direct consequences of environmental requirements becoming more rigorous as concern about carbon emissions grows. Moreover, the use of carbon fiber is an important part of the answer to these problems but brings on its own set of issues that need to …


Acoustic Simulation for Automotive and Heavy Equipment Industries

At present, noise quality is a crucial issue for automotive and heavy machinery manufacturers. In addition to the strict governmental regulations, it is important for automobiles to maintain the perception of quality in costumer’s mind. On the other hand, the sound of heavy machinery is a safety issue. Loud noises can make it harder for …


Use of Multidiscipline Solutions to Improve Automotive Noise, Vibration and Harshness

Simulation software is being used extensively around the world due to their accuracy and cost-effectiveness. Instead of using different simulation tools for every different type of testing process, engineers can use multidiscipline tools to better improve NVH (noise, vibration, harshness). MD solution tools can be used for many different areas of testing, including:  Analysis of …
