Instead of just propelling an instrumented vehicle into A 75 ton concrete block at speeds of 30 mile/h or more, crash investigators at vauxhall's safety laboratory in bedfordshire are also using a giant ram capable of imposing a 150 ton crushing force to crumple a vehicle slowly while they watch and even interrupt the process to make measurements. The crusher does not replace the live crash test, but provides safety engineers with data to feed into their computer programs which can then be used to predict how a car, van or truck will behave when it is accelerated into the concrete test block. In one particular instance, the crusher/computer study suggested that if, under impact the bonnet of one Vauxhall model were to buckle in two places instead of one, the vehicle's ability to absorb an impact would be significantly improved. Data from the crusher suggested that just four holes drilled in the bonnet reinforcing struts would ensure that bonnets would buckle in two places under impact. This, in turn, meant that the impact effects would be reduced in the main part of the body. /TRRL/
