Performance Test Methods for Wheeled Military Vehicles - Ground Clearance

A standard published within the framework of the NATO Standardization Agreement (STANAG) describes the ground clearance test methods and requirements carried out within the scope of performance tests of wheeled military vehicles. This standard includes test methods used to determine the performance of a wheeled military vehicle.

Ground clearance is the minimum distance between the lower end of the vehicle body or chassis and the road. Defines the lowest part of the vehicle relative to the ground. Most of the manufacturers define this dimension as an unladen vehicle, that is, as a vehicle that does not carry a load.

On the other hand, the directive 2007/2007/EC published in the European Union countries in 47 mainly includes the changes brought to the following legal regulations:

• Council directive 90/385/EEC on the approximation of the laws of the member states on active implantable medical devices
• Council directive 93/42/EEC on medical devices
• Directive 98/8/EC on the placement of biocidal products on the market in medical devices

In advanced laboratories, conformity assessment is carried out with the requirements and test methods defined in this directive.

One of the essential components in the design of military ambulances, in particular, is the ground clearance of the vehicle's undercarriage. Equations are formulated to predict the position of the ground lines, taking into account the vehicle's suspension characteristics and also its weight-loading condition. During the vehicle development phase, one of the crucial engineering decisions is determining the appropriate ground clearance for the vehicle. This ground clearance directly impacts the overall appearance of the vehicle, as well as the design of the suspension system and the underbody design. Otherwise, a delayed decision to change the ground clearance necessitates a change in the initial design of the suspension system and retesting the design. This also creates challenges related to the suitability of other components, such as the tire and exhaust system design.

Again, ground clearance refers to the ground clearance of the chassis of an unloaded vehicle closest to the ground.
