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”是新近发展起来的一种划时代的模型试验装置，它可以观测静定梁、超静定梁和弹性支承梁在集中荷载或分布荷载作用下的动力现象。该仪器可测量(1)支承反力、(2)剪力、(3)弯矩、(4)挠度和(5)挠度角，以及各种材料的杨氏模数。通过实验值与理论值的对比检验，进一步了解了梁理论的意义。1.通过将移动支承、铰支承和固定支承相结合，可以进行弹性支撑梁以及静定和不定梁的试验。2.在每个试验中都可以单独或以组合的方式观察到集中荷载、均布荷载、三角荷载、移动荷载和间接荷载。梁的尺寸(跨度和截面)和材料可以自由选择，包括具有特殊形状的截面，如变形截面和箱形截面。

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.
