摘要： A method for forming a test flume usable in hydraulic engineering and debris-flow hazard mitigation is provided. The test flume has a foundation flume and an expansion flume. The expansion flume has a lower edge connected to an upper edge of the foundation flume. A hydraulic radius of the test flume is determined based on a model test. A width of the foundation flume is selected based on a size of the test site of the model test. A coefficient is obtained and a width of the test flume is obtained. A cross section curve equation of the expansion flume is obtained based on the hydraulic radius of the test flume, the coefficient, the width of the test flume and the width of the foundation flume. The test flume is formed based on the cross section curve equation of the expansion flume.

摘要： The present invention belongs to the technical field of image measurement, and provides a motion measurement method and apparatus applied to a large multi-paddle wave simulation system. When the motion of the wave maker is measured, firstly site images are collected by the cameras; the mark point on each wave making paddle in the image processing boards is identified; and a central position is computed. Then, the central position is contrasted with the initial position to calculate displacement of the image plane and convert the displacement into the displacement on a physical space in combination with calibration parameters. Next, data is transmitted to the computer through the EtherCAT network, and coded identification is conducted on the data. Finally, comparative analysis is conducted on a measured value and a target value of the motion of the wave making paddle in the computer, thereby obtaining motion information of the wave maker. In the present invention, when the motion of the wave maker is measured, the problems of difficult target recognition and unstable motion tracking caused by nonuniform illumination in the experiment site as well as the problems of great time consumption of an image analysis algorithm and low efficiency of data transmission of multiple camera systems are fully considered.

摘要： Embodiments of the present invention are directed to an apparatus, system and associated method of operation that allows medium weight Class II equipment to be shock tested using a Medium Weight Shock Machine (MWSM) in a manner that adequately simulates the required shock response exhibited when subjected to underwater explosion (UNDEX), Heavyweight testing utilizing a FSP. Advantageously, such an apparatus, system and associated method allows for testing of Class II medium weight (e.g., about 500-4500 lbs.) equipment (e.g., submarine and surface vessel equipment) utilizing an MWSM instead of Heavyweight testing utilizing a Floating Shock Platform (FSP). Testing of Class II medium weight equipment in this manner significantly reduces cost of testing such equipment and increases safety associated with testing such equipment.
