Bull Bar Validation

Frontal Vehicle Protection System Testing

The APV Test Centre offers various types of Frontal Vehicle Protection System (FVPS) tests.

  • Sled test method, to test airbag compatibility and dynamic structural integrity analysis at the ADR69 velocity.
  • Full vehicle test to validate airbag and compliance with ADR69.
  • Frontal impact methods to simulate animal strikes.

Sled test method

APV-T has developed a sled test method to assist manufacturers of Frontal Vehicle Protection Systems (FVPS), or bull bars and nudge bars, to assess the effects of their FVPS on a vehicle structure during a crash event. 

In all FVPS testing, the sled is equipped simulate the real vehicle mass, the original chassis structure and stiffness profile. The APV FPVS Airbag Compatibility test uses sled mounted accelerometer data to evaluate and compare the FVPS 'Crash Pulse' (Deceleration/Time) and Delta V curves with the vehicle's original equipment bumper bar at the 'airbag fire/no fire' threshold velocity of 16km/h.

APV also offers FPVS rigid barrier sled testing at the ADR69 specified velocity of 48 km/h intended to support product development and the design verification process. All bull bar sled testing offers high-speed video services to further evaluate the impact characteristics.

The intended purpose of sled testing is to allow dynamic assessment of a FVPS structure on a system intended to replicate the appropriate vehicle type. This testing will allow manufacturers to exhibit reasonable precaution and due care in design of their FVPS by demonstrating that their product provide similar impact characteristics to the original vehicle, does not detach during impact and is not likely to adversely affect airbag deployment characteristics and the original vehicles ADR compliance.

Full Vehicle Test Method

A full vehicle crash test demonstrates that the alterations to the vehicle structure have not affected the original compliance of the vehicle.

Using our accredited full vehicle crash test facility, bull bar manufacturers can test to:

  • Airbag compatibility, where airbags 'must fire' at a threshold velocity of around 16km/h
  • Original vehicle ADR 69 full frontal Compliance at 48km/h

Manufacturers can also test to different load cases such as low speed airbag 'must not fire' velocity, ADR 73 offset frontal 56km/h an additional ADR compliance test for class M vehicles only and ANCAP 64km/h offset frontal consumer test.

Frontal Impact Test Method

We can also perform crash tests to simulate hitting large animal (80kg) and small animal (23kg). This can be done so that bull bar manufacturers can investigate the subsequent performance of their product.

Tests can be setup, using sandbags as animal equivalents and massed to simulate the required animal type. The effects of both central and offset impacts can be investigated at velocities of up to 80km/h depending on customer requirements.
