Slope road simulation device and method for passenger car testing

Abstract

The invention relates to a slope road simulation device and method for passenger car testing. The slope road simulation device comprises a wheel support surface used for being matched with a wheel support at one end of a passenger car and a lifting machine used for lifting the other end of the passenger car so as to enable the passenger car to have an inclined attitude. According to the slope roadsimulation method applying the above device, the wheels at one end of the passenger car are supported on a wheel support surface, the other end of the passenger car is lifted by a lifting machine, and the passenger car is enabled to incline so as to simulate the attitude of the passenger car on a slope road. The front or back end of the passenger car is lifted by using the lifting machine to enable the passenger car to have an inclined attitude so as to simulate the state of the passenger car when being on the slope road, thereby being capable of realizing the inclination of the passenger carwithout driving the passenger car to the slope road, and facilitating the testing for the passenger car. In addition, the front or back end of the passenger car is lifted by using the lifting machineso as to enable the passenger car to incline, so that there is no need to lift the whole passenger car, and the operation is convenient.

Description

technical field [0001] The invention relates to a slope road simulation device and method for passenger car test. Background technique [0002] Article 3.017 of my country's road industry standard JTG B01-2003 stipulates that the maximum slope of the country's newly built roads is θ=arctan (10%)≈5.712°. [0003] Due to the different terrains in various regions of our country, the slopes of roads in different regions are also different. In order to ensure that the automatic opening passenger door of the bus can be opened and closed normally on roads with any slope, and to ensure that the clamping force of the passenger door is moderate (strength) If the force is too large, it is easy to pinch passengers, and if the force is too small, the passenger door cannot be opened and closed normally), which requires opening and closing tests on the passenger doors of passenger cars on roads with different slopes, and the present invention aims to provide a passenger car test The simul...

[0003] Due to the different terrains in various regions of our country, the slopes of roads in different regions are also different. In order to ensure that the automatic opening passenger door of the bus can be opened and closed normally on roads with any slope, and to ensure that the clamping force of the passenger door is moderate (strength) If the force is too large, it is easy to pinch passengers, and if the force is too small, the passenger door cannot be opened and closed normally), which requires opening and closing tests on the passenger doors of passenger cars on roads with different slopes, and the present invention aims to provide a passenger car test The slope road simulation method, without the need to drive the experimental bus to the slope road, can also realize the passenger car tilting according to the predetermined angle, and ensure the accuracy of the slope. The slope value can achieve any slope value stipulated by domestic highway regulations
