This standard is applicable to bridge vehicles, passenger cars, trucks and off-road vehicles. According to the requirements of the use of high-speed vehicles, the method of this standard can be used to evaluate the compensatory performance of the vehicle from the impact of the vehicle passing over a single convex block on the passengers and cargo. 2 Test cases
2.1 Road
The test road is a straight cement road surface with a small surface and a flat road surface. 2.2 Wind headwind
According to the provisions of Article 2-2 of C457-985 Automobile Ride Comfort Test Method 3. 2.3 Automobile Technical Condition
According to the current provisions of Article 2.3 of 457G--:9R:
2.4 Automobile Load
Before the automobile turns, the vehicle shall be tested uniformly. All vehicles shall be tested under full load conditions. Half load and empty load tests may be added as needed. 2.5 Personnel Loading System
According to the provisions of Article 2.5 of G467G:993:
2.6 The riding situation of people
According to the provisions of 2.6 in G3457--185, it is necessary to use a safer vehicle. 2.7 Test vehicle construction
a) The test vehicle speed is 10.20.30.4c53.s0km/h6 The vehicle speed is in accordance with the provisions of 2.7.3 in 64970-1985. 3 Test instruments and devices
3.1 Test instruments
My test system should be composed of test instruments, and its performance should be stable and reliable, with a standard dynamic range of 0.3~1mH. The instruments specified in Part 3 of 4370-1985 can be selected, and the acceleration sensor and the course will not be less than 10:3.2 The standard adopts two shapes of single convex as the taste of impact: triangle and long collection, and promotes the essential material, outsourcing history 3.2.1 The triangle occupies the block shown in Figure 1. Its body is: corrective vehicles, travel passenger cars and trucks with a total mass of less than 41, etc. - one center mF5) All vehicles (except travel passenger cars), off-road vehicles 2 total pressure plate size 1t less than or equal to 20t c) Trucks with a total mass of 2t.

3.2.2 The structure and parameters of the long control cam are shown in Record A. This cam is applicable to various types of automobiles. 4 Test method
4 The total load sensor is installed on the following ends: 1) the left front and rear seats and the bottom of these seats are on the floor: a) sedan
b) the floor of the front axle and rear axle with the driver's seat and the last row of seats and the floor of these seats: trucks and off-road vehicles - on the bottom floor, the side panels and vertical pressure plates of the vehicle are installed at the center of the load reducer, and the load reducer is installed in close contact with the human body, and the potential plate used for the load reducer is installed between the human body and the load reducer: its structural type is in accordance with the specifications in Appendix 1 of GB40701585.
4.2 Place the head on the test road and adjust the distance between the two blocks. To ensure that the left and right wheels of the car pass the test, two bumps should be placed on a level perpendicular to the direction of the car's travel: 4.3 During the test: The car passes the bumps at the specified speed. The car runs at any speed before the car passes the speed limit, and the maximum speed is measured by the measuring device. When the car's wheel is close to the bump, the recording starts. When the car passes the bump and the bumps are eliminated, the recording stops. 4.4 During the test, the three-shear bump is used as the pulse, and the test can be made according to the needs: the test speed should not be less than 8.
5 Level evaluation
The level performance of the car is evaluated by the absolute front speed 2, that is, the speed characteristics: Www.bzxZ.net
multiplied by the negative, the maximum (the first value) acceleration distance delivered to the occupants is multiplied by the negative. Seat bottom agent ground light, car use, listed in the state before. -Detailed price. 6 Data processing and calculation of evaluation indexes
6. Data processing
When using a signal processor for data processing, the time required is: 4-U.3.6.2 Calculation of evaluation indexes
The maximum (absolute value) plus the maximum (absolute position speed) plus the virtual response formula is: m531
