Title:
DYNAMIC FORCE MEASURING SYSTEM AND FORCE MEASURING METHOD FOR RAIL VEHICLE COLLISION
Document Type and Number:
WIPO Patent Application WO/2022/105398
Kind Code:
A1
Abstract:
Provided by the present invention are a dynamic force measuring system and force measuring method for rail vehicle collision. The dynamic force measuring system for rail vehicle collision comprises: a first flat plate, at least one sensor group and a uniform force plate, wherein each sensor group comprises at least two sensors, and the sensors are arranged at preset positions on one side surface of the first flat plate. The uniform force plate is located on the side of the sensors away from the first flat plate. As can be seen, in the present solution, the uniform force plate is arranged on one side surface of the sensor group, and impact stress is dispersed by means of the uniform force plate, so that the impact force acting on the sensors is reduced, thereby improving the impact resistance of the sensors. In addition to the foregoing, in the present solution, due to the existence of the uniform force plate, the sensors may also be distributed in some regions of the uniform force plate, so that the total number of sensors in the entire dynamic force measuring system is less than that in existing methods for tiling the sensors in sequence. Hence, the present solution may reduce system costs.
