The present invention is divided into the basic simulation conditions of five major vehicle driving models:

(1) The vehicle will have a basic motion posture of up and down bumps in driving conditions. There is an up and down vibrator at the rear of the present invention, which can produce vibrations of different frequencies when people step on it constantly, which is more in line with the driving posture of the vehicle than the electric one.

(2) Due to the driver's driving and the road, the vehicle will cause the driver to generate a motion law that swings back and forth relative to the seat. The rear part of the present invention has a triangular bracket plate at 120 degrees to each other, which can produce irregular forward and backward motion under the condition of external force, so as to achieve the attitude that the driver moves forward and backward when the vehicle is running.

(3) The vehicle will inevitably brake due to road conditions during driving. The invention is used for installing the front brake disc. Therefore, it is convenient to study the mathematical relationship between depressing the brake pedal and the brake braking force that can be generated. The brake system model in the vehicle dynamics simulation generally uses test data to fit the relationship between the brake braking force and the brake pedal displacement, thereby simulating the attitude of the vehicle in motion.

(4) Driving in a straight line is the most basic movement mode in the process of driving a car. In the process of straight-line driving, the change of vehicle speed is related to the driving force, rolling resistance, braking force, gradient resistance and wind resistance of the vehicle. The invention can realize the driving condition simulation of the vehicle under the drive of external force, thereby simulating the posture of the linear motion of the vehicle.

(5) The invention is equipped with a steering machine, which can simulate the steering system of an automobile, and is convenient for the research on the steering stability, safety and reliability of the vehicle. The vehicle driving direction model can be regarded as the functional relationship between the vehicle's steering angle and the steering wheel angle. First, the steering system of the vehicle is assumed to be a rigid system, and the change of the vehicle's driving direction follows the control of the steering wheel angle without delay. The function of the vehicle steering system is to enable the driver to steer the front wheels by operating the steering wheel to realize the steering movement of the vehicle, thereby simulating the posture of the vehicle steering movement.

The beneficial effects of the present invention are: (1) the seat can move irregularly back and forth along the slide rail 10 according to the rotation of the triangular rotating disc; The effect of shock absorption; (3) the height and angle of the steering wheel are adjusted through the steering wheel bracket 9, which is convenient and reliable: (4) the steering machine 4 is connected to the column seat 25 through the transverse tie rod 24 to realize the steering structure is simple and reliable, and the cost is low: (5) the body With the characteristics of compactness, flexibility, multiple degrees of freedom, economical and reliable characteristics, the vehicle frame that can simulate the driving test environment of the vehicle has real practicality, is easy to operate, is easy to popularize, and has a structure with multiple test effects.
