摘要
针对光电经纬仪等高准确度仪器设备在运输过程中,对车载情况下产生的冲击和振动提出的具体要求,采用一套基于金属钢丝绳减震器的减振系统及加固装置对其进行抗振动防护.分析了车栽情况下该减振系统的数学模型,并以某型号经纬仪模型为例,将其放置于满载质量15吨的某型号越野汽车中,在砂石路况下以30 km/h的车速进行跑车试验,测得其加速度振动响应小于0.5 g,冲击响应小于2.8 g.
A method of cushioning system based on eight steel wire shock absorbers and a strengthening mechanism for the vehicular photoelectric transit, which was for reducing the influence of the vibration and shock and in this condition, has been proposed. Through analyzing the mathematical model of the shock absorption system, the relationship of the excitory input displacement of the vehicle and the output acceleration of the transit has been established. For verifying the practicability of this shock absorbing method, the cushioning system was installed on a 15 tons wagon truck, which was running on the sandgravel surface at a speed of 30km/h. The results of the tests indicate that the output vibratory acceleration of the transit is less than 0.5g,and the shock acceleration is less than 2.8g.
