汽车座椅强度性能试验台设计

Design on Strength Test Bed of Automobile Seat

汽车座椅是汽车的重要部件之一,其性能好坏直接影响汽车安全性和舒适性。在相关试验标准基础上,设计了一种汽车座椅强度性能试验台。试验台采用液压控制静力加载机构和电机控制冲击摆锤加载机构准确模拟了汽车座椅的试验工况,对其总体方案、静力加载机构、摆锤加载机构和液压控制系统进行了详细设计。该试验台能完成汽车座椅靠背及调节装置强度试验、汽车座椅头枕静态性能试验和汽车座椅靠背及头枕吸能性试验,具有通用性强,精度高,成本低,使用方便等优点。

The seat is an important component of automobile,which performance affects directly upon security and comfort of automobile.Based on test standard,a strength test bed of automobile seat was developed.With static hydraulic loading device and pendulum impact loading device driven by motor,the strength test condition of automobile seat was simulated accurately,and the general plan,static loading device,pendulum loading device and hydraulic control system were designed in detail.The test bed can implement tests such as strength test for seat backrest and regulating device,static performance test for seat headrest and energy absorption test for seat backrest and headrest with the characteristics of strong universality,high accuracy,low cost and easy use.
