缓降器装置的研究.docVIP

摘 要 本文首先对缓降器装置的研究现状进行了有效的分析，发现大多数装置结构原理复杂，操作繁琐，有些产品需要进行专门的培训才能完全掌握其的操作方法；部分产品甚至还需要电力驱动，断电时无法工作。 为了改善这些不足之处，运用TRIZ理论创新设计，设计出一种基于负反馈闭环系统的缓降器装置，原理是利用物体本身的自重，通过机构的转换，产生阻止物体快速下落的阻力，从而使其在到达地面时速度减少，安全到达地面。然后对该装置的各个零件进行了设计和校核。最后通过静力学计算，分析该缓降器装置所能实现的功能，并加工出样机，通过实验验证了这些功能，通过实验测试可以达到高楼逃生人员安全落地速度小于3 m∕s，其不仅可以用于缓降重物，也可用于紧急情况下的高楼逃生，有效地减少了人民群众的生命和财产的损失。 关键词： 缓降器 TRIZ理论 负反馈闭环系统 包角 高楼逃生装置 Abstract This paper firstly device to study status of effective analysis of HuanJiangQi, Through investigating the market we found that most device structure is complex, operation principle of tedious , some products need special training to fully grasp its operating methods, and some products even need electric drive power cuts cannot work. In order to improve these deficiencies, using the TRIZ theory , this paper design a HuanJiangQi which is based on negative feedback from the closed-loop system. Our product‘s principle is to use the object itself, through the agency of self-respect,which can produce the conversion fast falling resistance to stop objec decreased all the speed when flow down the ground,this produce allow items safe reaching the ground.Then we have designed and checked the various parts of this device. Finally, through calculation analysis of the statics HuanJiangQi device can realize the function and work out a prototype, we have verified by the experiments these functions. through the test can achieve safe landing speed high-rise escape personnel are less than 3 m/s, it not only can be used to slow down weight, also can used for emergency escape buildings, effectively reduce peoples life and property.
