Stability effects of sloshing liquids and hanging meat

In July, 2002 New Zealand introduced a minimum rollover stability requirement for most large heavy vehicles. This requirement specified that heavy vehicles must achieve a Static Rollover Threshold (SRT) of 0.35 gravitational units or more. In New Zealand a relatively simple computer-based method known as the SRT Calculator has been developed and has been shown to have good accuracy. This is the most widely used method for determining SRT. However, the SRT Calculator does assume that the load is firmly secured to the vehicle and does not move relative to the vehicle. This assumption is commonly used in the other computer-based methods as well. For most load types this assumption of a well-secured load that does not move relative to the vehicle is valid. However, for two specific load types: liquids in tankers and hanging meat, the assumption is clearly not strictly correct at least some of the time. The purpose of this review is to quantify the effect that sloshing liquids and swinging hanging meat have on the rollover stability of the vehicle. The differences in behaviour and magnitude of the effect between the two types of moving load will be compared and the effect on safety will be estimated.
