Challenge

Client was developing a range of vehicle security barriers in the form of retractable bollards. The design was to conform to the requirements of the US Department of State ratings (Kx) and/or the equivalent PAS 68 standard in the UK. These standards involve high performance requirements of energy absorption by the bollard.

 

Challenge was to study the behaviour of the Bollard assembly under the impact of 6.8 ton Vehicle at 100Km/hr. Broadly, the test involves impacting a 15000 lb truck onto the barrier at specified speeds and then measuring the penetration on the truck bed behind the barrier. The lesser the penetration the better the design is, as more energy gets absorbed in smaller distance travelled.

Timeline

February 2014 to
July 2014

Non-linear Dynamic analysis of the baseline design under specified testing conditions was carried out. Design modifications and optimization were carried out to meet/ exceed performance targets.

Key Engineering Analysis

1. Nonlinear explicit FE analysis was used.

2. The design conformed to the requirements of the US Department of State ratings (Kx) and/or the equivalent PAS 68 standard in the UK.

3. Design modifications and optimization were carried out to meet/exceed performance targets.

Solutions

Vehicle Characteristic: Medium duty trucks (diesel engine) was a test vehicle.

Payload attachment: The payload was required to be firmly attached to the cargo bed to ensure the cargo realistically transfers its kinetic energy on impact. In our case a cuboid of appropriate density was attached to the cargo bed to model the sand filled drums used in the actual testing.

Non-linear Dynamic analysis of the baseline design under specified testing conditions was carried out. Design modifications and optimization were carried out to meet/exceed the performance targets.

Full vehicle FE model of the corresponding vehicle was not supplied by the customer, hence a free, downloadable vehicle model was downloaded from the internet.

Key Highlight

    ROI for the client

    Faster product development cycle.

    First time right product and better warranty estimate.
