WEBPolice Radio 10-Codes. Ten-codes, also known as 10-codes or ten signals, are code words used by many police officers to aid with voice communication. The codes were originally developed in 1937 to allow for brevity, clarity, and standardization of messages transmitted over radio channels. On old radio systems, channels were limited so messages .

vehicles in low speed crashes. 2. Stability – vehicle bumpers need to be tall and wide enough to remain engaged with the bumpers of other vehicles despite vehicle motion due to loading, braking, etc. 3. Energy-absorption – vehicle bumpers should absorb low speed crash energy without damage to other parts of the vehicle. For model year 1979, the standard required that there be no damage to safety-related parts and exterior surfaces not involving the bumper system (e.g., sheet metal; lamps; and fuel, exhaust and cooling systems) with damage to the face bar and its fasteners at impact test speed of 5 mph front and rear impacts with barrier and pendulum; 3 mph .

Low-Speed Impact Bumper System Test Procedure for Passenger Vehicles(STABILIZED Oct 2019) J2319_201910 The scope of this SAE Recommended Practice is restricted to the testing of original equipment on passenger vehicles and to provide for a uniform industry test procedure.To test the resiliency of its bumper during low-speed collisions, a 1 000-kg automobile is driven into a brick wall. The cars bumper behaves like a spring with a force constant 5.00 $$\times 10^6$$ N/m and compresses 3.16 cm as the car is brought to rest.
To test the resiliency of its bumper during low-speed collisions, a 2 760-kg automobile is driven into a brick wall. The car's bumper behaves like a spring with a force constant 4.00 10 6 N/m and compresses 3.38 cm as the car is brought to rest. What was the speed of the car before impact, assuming no mechanical energy is transformed or transferred away during impact with the wall?RCAR Low-speed structural crash test protocol 8 / 18 Issue 2.3 5.0 TEST FACILITY AND TEST VEHICLE PREPARATION - REAR IMPACT The test facility and preparation of the test vehicle shall be similar to that described for the front impact (section 4.1 and 4.3), with the following additions/exceptions: 5.1 Barrier set up and position During accidents under low speed impact the bumper beam absorbs the kinetic energy by deflection and under high speed the bumper beam absorbs energy by deformation [5].

It is found that in the dynamic three-point bending and sled low-speed impact, the bumper beam absorbs most of the kinetic energy; while the energy absorbing box does this in the 40% offset crash. The ultimate internal energy of sled low-speed impact, three-point bending and 40% offset crash are 2374.0 J, 8226.5 J and 1721.0 J, respectively.
The Bumper Pendulum (BP) is intended for low-speed bumper impact testing according to worldwide regulations like ECE R42 and FMVSS Part 581.

impact. Schematic diagram of a low-speed impact test is shown in the Fig. 2. Figure. 2 Low-Speed Impact test Since the impact between the front bumper and an impactor is nonlinear and transient analysis are involved, this phenomenon can be very complicated in low-speed crashes. Therefore, the automobile In 2006, the Insurance Institute for Highway Safety (IIHS) released a new Low Speed Bumper Test Protocol for passenger cars1. The new test protocol included the development of a deformable barrier that the vehicle would impact at low speeds. IIHS positioned the new barrier to improve correlation to

The car's bumper behaves like a spring with a force constant 6.00 10 6 N/m and compresses 3.5 cm as the car is brought to rest. What was the speed of the car before impact, assuming no mechanical energy is transformed or transferred away during impact with the wall?speed into the barrier at its normal running attitude. Impact Speed Measurement Impact speed is measured using an optical speed sensor mounted on the side of the vehicle and aimed downward to detect reflective tape strips on the crash hall floor. The leading edges of the strips are spaced 456 mm apart.
