5、 Mount Device or SystemsRATIONALEThis SAE Recommended Practice was developed by members of the SAE Truck Crashworthiness Committee in support of the ambulance industrys need to apply science to the design and testing of the equipment mount devices or systems used in the ambulance patient compartment

6、. The Recommended Practice was validated collaboratively by industry and government partners through extensive testing funded and managed by the National Institute for Occupational Safety and Health, the Department of Homeland Security and the Ambulance Manufacturers Division of the NTEA. Input load

7、ing for the dynamic testing was generated using the vehicle specific crash pulses described in SAE J2917 and SAE J2956, respectively. An independent analysis of the testing methodology and resulting data was performed by government and private members of the automotive testing community.1. SCOPEThis

8、 SAE Recommended Practice describes the dynamic and static testing procedures required to evaluate the integrity of an equipment mount device or system when exposed to a frontal or side impact (i.e., a crash impact). Its purpose is to provide equipment manufacturers, ambulance builders, and end-user

9、s with testing procedures and, where appropriate, acceptance criteria that, to a great extent, ensure equipment mount devices or systems meet the same performance criteria across the industry. Prospective equipment mount manufacturers or vendors have the option of performing either dynamic testing o

10、r static testing. Descriptions of the test set-up, test instrumentation, photographic/video coverage, testfixture, and performance metrics are included.2.

15、means offixation, which may have fixed or adjustable positions. Also includes all hardware provided for holding the intended device(s).3.3 “Fracture” means cracking or tearing of the equipment mount system.3.4 “Load Bearing” means any component of the equipment mounting device or system, hardware an

16、d fixtures, or litter-mounted device or system that is required to maintain the equipment in a secured position.3.5 “Load Path” means a series of load bearing components.3.6 “Mounting Hardware”: Fasteners and other associated components that are used to affix an equipment mounting device or system t

17、o the interior of an ambulance or to a litter.3.7 The “Peak Acceleration” is the maximum “g” loading for the applicable pulse corridor as described in either SAE J2917 or SAE J2956.3.8 “Test Analog/Device”: A rigid inert structure that represents the physical dimensions, weight and center of gravity

18、 in all axes of the equipment for which the mounting device or system was designed to restrain. It provides connection points to attach to the intended mounting device or system that match those found on the actual piece of equipment to be mounted in the equipment mounting device or system.3.9 The “

19、Quasi Static Applied Load (QSAL)” is the load to be applied in the static test of an equipment mounting device or system in lieu of a dynamic test. The QSAL is defined mathematically as the Equipment Weight times the Peak Acceleration times the Dynamic Amplification Factor4. DYNAMIC TEST REQUIREMENT

DYNAMIC TEST CONDITIONSThe following conditions apply:5.1 Due to the large number of mounting locations for each mounting device or system, a rigid sled test fixture s

22、hall beused. For example, a horizontal surface would represent a countertop or floor mount while a vertical surface would represent a wall.5.2 These tests are considered destructive therefore, deformation and fracture shall be expected and consideredacceptable within the criteria of Section 8. At th

23、e option of the manufacturer, a new production equipment mounting device or system may be used in each test attitude.SAE INTERNATIONAL J3043 Issued JUL2014 Page 3 of 66. DYNAMIC TEST PROCEDURESThe equipment mounting device or system manufacturer is responsible for determining all recommended product

24、 or product mount orientations relative to the patient compartment of the ambulance. In lieu of testing all orientations, theequipment mount device or system manufacturer may determine the worst case orientation to be tested where other orientations can be shown sufficient by comparative analysis. I

25、n most cases a minimum of two tests (tension and shear) should be anticipated. The exception would be a completely symmetrical installation such as a cylindrical pole mount.6.1 Install the equipment mounting device or system directly to the sled device as described in the manufacturersinstructions.

26、Preservation of the mount design intent must be maintained in order to replicate performance when mounted in an ambulance or to a litter.6.2 Install test analog/device per manufacturer provided instructions.6.3 For equipment mounting devices or systems that retain compressed gas cylinders, such as o

27、xygen tanks or fire extinguishers, the installed cylinders should be made non-volatile or an analog device of equivalent weight shall beused.6.4 Test in accordance with dynamic sled test facility protocol to achieve dynamic loading as defined in SAE J2917 and/or SAE J2956.7. POST DYNAMIC-TEST INSPEC
