激光动态粒子分析(PDA)是目前公认的最有效的同时测量粒子尺寸和速度的技术。该技术已广泛地应用于物理、动力等各个行业,但尚未应用于建筑领域。为此,本文提出了一种能够对建筑、城市空间进行精确测量的激光动态分析技术,并设计制作了相应的设备装置。同时,以上海同济新村居住小区为试验对象建立起模拟结构,运用PDA技术成功进行了测试。试验结果表明该技术方法有效、能够实现对建筑、城市空间进行精确测量,从而对整个建筑、城市空间进行有效的设计和分析。
Laser Dynamic Particle Analysis (PDA) is by far the most effective technique for simultaneous measurement of particle size and velocity. The technology has been widely used in physics, power and other industries, but not yet used in the construction field. Therefore, this paper presents a laser dynamic analysis technology that can accurately measure the building and urban space, and design and manufacture the corresponding equipment. At the same time, taking Shanghai Tongji New Village residential area as the test object to establish the simulation structure, the PDA technology was successfully tested. The test results show that the method is effective and can accurately measure the building and urban space so that the entire building and urban space can be effectively designed and analyzed.
