Vehicle-bridge system wind tunnel test in vehicle movement situation be obtain vehicle-bridge system aerodynamic characteristic under situation of movement the most effectively, the most direct method.In vehicle-bridge system wind tunnel test under situation of movement, after vehicle movement gets up, all need to brake, if braking effect is bad, easily cause even force balance damage of thermometrically.
The heaps that adopt were established the cushions such as sponge or utilized the modes such as gravitional force to brake more in the past.Front a kind of braking method, is to utilize a car to collide cushion to realize braking, the bad control of braking effect, and need to carry out a large amount of debugging work; Rear a kind of mode of braking, for the car brakeing under friction speed, needs the vertical ring-shaped guide rail of differing heights, installs huge and high to place space requirement.
Based on this, need badly a kind of effective, adaptable and to site condition the vehicle-bridge system wind tunnel test Vehicular brake device without particular/special requirement.
Utility model content
The purpose of this utility model be to provide a kind of and be convenient to implement, the simple and reliable locomotive bridge system wind tunnel test Vehicular brake device based on Stroke Control.
For achieving the above object, the utility model is implemented according to following technical scheme:
A kind of locomotive bridge system wind tunnel test Vehicular brake device based on Stroke Control, be connected on vehicle-bridge system, vehicle-bridge system comprises bridge, bridge is provided with guide rail, comprise roller, retarding spring, connection cord, junction button and traction base, the traction base roller that described traction base arranges by lower surface rolls and coordinates with guide rail, the lower surface of traction base is provided with junction button, testing vehicle is connected on traction base by force balance, connection cord one end is connected with the junction button on traction base, the other end is connected with retarding spring, retarding spring and connection cord are wound around and are fixed on roller, roller is fixed on the upper surface of an end of bridge.
As preferred version of the present utility model, described junction button is arranged on the traction base lower surface of testing vehicle afterbody.
As preferred version of the present utility model, the summation that the length of described connection cord and retarding spring extend later length is not more than the overall length of bridge.Retarding spring is convenient to change, and connection cord length is convenient to regulate, and connection cord adopts high-strength material to make, and shape is very thin as plumbous hair line.
The Vehicular brake device method for making of the above-mentioned locomotive bridge system wind tunnel test based on Stroke Control, concrete steps are as follows:
1, make traction base and junction button;
2, calculate the weight of traction base and testing vehicle;
3,, according to the requirement of test, determine reference position and the maximum braking distance of retaining segment;
4, meet the spring constant of the retarding spring of brake request according to calculating such as the general assembly (TW) of draw-gear, haulage speed and maximum braking distances;
5, connection cord one end is connected with the junction button at traction base trailer position, the other end is connected with retarding spring, and retarding spring and connection cord are wound around and are fixed on roller, and roller is fixed on bridge termination.
Compared with prior art, the utility model beneficial effect:
The utility model is novel, utilize dexterously Stroke Control principle, in the time that traction base moves to precalculated position, retarding spring starts to bring into play braking action, because spring is replaceable and connection cord length is convenient to regulate, make this clamping device there is better braking effect to the moving vehicle of different trailing weights, different haulage speeds; In addition, because junction button is arranged on the traction base lower surface of testing vehicle afterbody, braking procedure is similar to vehicle rear wheel braking, the upset that can effectively avoid testing vehicle to cause due to high-speed motion.
The utility model principle is simple, practical, can be widely used in the vehicle-bridge system wind tunnel test car brakeing in vehicle mobile situation.
