Research on Trial Prodacts of Dynamic Experimentation Apparatus of Beam Structure

梁理论是所有工业工程师必须掌握的基本知识之一。“梁仪”是新研制的具有划时代意义的模型实验装置，可以观察静定梁、静不定梁和弹性支承梁在集中或分布荷载作用下的动力现象。本仪器能够测量各种材料的(1)支承反力，(2)剪力，(3)弯矩，(4)挠度，(5)挠度角，以及杨氏模量。因此，通过对得到的实验值和理论值的比较检验，该装置可以更深入地理解光束理论的意义。将活动支承、铰接支承和固定支承结合起来，进行了弹性支承梁以及静定和非定常梁的试验研究。在每次试验中，集中荷载、均布荷载、三角荷载、移动荷载、间接荷载等荷载可以单独观察，也可以组合观察。梁的尺寸（跨度和截面）和材料可以自由选择，包括变形截面和箱形截面等特殊形状的截面。

The beam theory is one of the basic knowledge to be acquired for all industrial engineers. The "Beam Apparatus" is a newly developed epochmaking model experimentation apparatus which can observe dynamic phenomena of statically determinate beams,statically indeterminate beams, and elastic support beams under concentrated or distributed loading. This apparatus is capable of measuring (1)support reaction,(2)shearing force, (3)bending moment,(4)deflection and (5)deflection angle, as well as Young's modulus of various materials. Thus the apparatus allows deeper understanding of the significance of the beam theory through comperative examinations between obtained experimental values and theoretical values.1.By combining the movable suport,hinged support and fixed support, experiments of the elastic support beam as well as of the statically determinate and indeterminate beams are also available.2.Loads such as concentrated load, uniform load, triangular load, moving load and indirect load can be observed either individually or in the combined style in each experiment.3. Beam dimensions (span and section) and material can be selected freely, including sections having special shapes such as deform section and box section.
