摘要： A method and device for determining force exerted on a rolling vehicle wheel. Firstly, data on a relationship between a force exerted on a vehicle wheel and a physical parameter such as strain of the radius part of the wheel at predetermined measuring positions are obtained. Using the obtained data on the relationship, a formula for the force is made. Then, the vehicle wheel is measured for the physical parameter during rolling, and using the measured physical parameter and formula, the force is calculated. The force may be a vertical force, lateral force, longitudinal force or self aligning torque. The physical parameter may be the magnitude of a radial strain.

摘要： A device for measuring action force of a wheel includes a vehicle axle upon which the wheel is mounted, the vehicle axle having a stress neutral line, and a stress detecting sensor having at least one strain gauge. The stress detecting sensor is disposed within the vehicle axle so as to detect at least one of a horizontal shear stress and a vertical sheer stress with the at least one strain gauge being one of aligned with or proximate the stress neutral line thereby permitting substantial removal of axle torque influence from an output of the stress detecting sensor. A signal processing circuit processes the output of the stress detecting sensor.

摘要： A method is provided capable of improving the accuracy of estimations of quantities that represent the state of a vehicle, such as vehicle speed, wheel slip ratio, wheel speed along the ground, longitudinal wheel force and the vehicle body sideslip angle, or values related to the quantities that represent the vehicle state, using a simple and inexpensive method. A tire longitudinal force computing unit 81 calculates longitudinal forces F1 to F4 of each of the wheels by substituting a coefficient of friction null, which is adjusted such that a deviation between a detected value of a longitudinal acceleration Gx and an estimated longitudinal acceleration Gxe is zero, an estimated vehicle speed Ve, slip ratios S1 to S4 of each of the wheels calculated based on detected values of sensors 11 and 31, loads W1 to W4 of each of the wheels, calculated based on detected values of sensors 12 and 61, and lateral forces Y1 to Y4, into an equation related to a predetermined tire dynamics model. A longitudinal acceleration estimating unit 82 calculates an estimated longitudinal acceleration Gxe based on the longitudinal forces F1 to F4 and a predetermined movement equation. An integrator 43 integrates with respect to time the estimated longitudinal acceleration Gxe, and calculates an estimated vehicle speed Ve.

摘要： Action force of a wheel is measured in order to measure the road surface frictional force, vertical drag, road surface friction coefficient, etc. Means for making these measurements can be constituents of an antilock brake system, traction control system, etc. These constituents may also serve as devices for measuring stresses generated in other structures. In a specific example, axle of a vehicle is formed with a hole, a stress detection sensor is installed in the hole and secured in position with the aid of a spacer element, and a detection signal from the stress detection sensor is processed in a signal processing circuit.

摘要： Method and apparatus for determining dynamic lateral and vertical wheel-rail forces. Axle bending sensors and axle load cells provide signals to a computer programmed to calculate lateral and vertical wheel-rail forces. These forces are used as the basis for comparing the effects of a variety of car truck design criteria and track conditions. Comparison of forces developed by the same equipment on different runs over the same trackage discloses track condition changes between runs.

摘要： Provided are methods for measuring forces exerted on rails or such like as a cause of the transit of vehicles on said rails, for determining the values of different parameters, and for calculating coefficients or other variables. Also provided are systems of devices that allow for the taking of values and for the recording, processing, and sampling of the resulting information based on measurement methods that allow directly measuring the lateral force, in a more simplified manner of installation resulting in lower cost in sensors and with greater precision based on the configuration of said sensors and their individual valuation.
