【摘要】：与普通空气弹簧不同,高度阀内置空气弹簧是将高度阀设置在空气弹簧气囊内部形成的一体式结构。由于其结构较特殊,目前还没有专门针对这种结构空气弹簧的性能测试方法。为了得到高度阀内置空气弹簧的性能测试方法,防止因测试方法不当造成高度阀内置空气弹簧的损坏,针对一款汽车驾驶室悬置高度阀内置空气弹簧进行了性能测试。测试参照普通空气弹簧的性能测试方法进行。测定了高度阀内置空气弹簧和外置高度阀的普通空气弹簧的载荷-位移曲线和动刚度-加载频率曲线。依据测试结果的对比分析可以发现:高度阀内置空气弹簧和普通空气弹簧性能曲线的变化趋势一致,而且所测定的曲线比较符合实际行车情况。说明参照普通空气弹簧的性能测试方法对高度阀内置空气弹簧进行性能测试是可行的。由此可知,高度阀内置空气弹簧与普通空气弹簧的性能测试方法具有一致性。
[Abstract]:Unlike ordinary air springs, the height valve built-in air spring is an integral structure in which the height valve is placed inside the air spring airbag. Because of its special structure, there is no special test method for the performance of air spring. In order to obtain the performance test method of the built-in air spring of the height valve and prevent the damage of the air spring of the height valve caused by the improper test method, the performance test of the built-in air spring of a car cab mounting height valve was carried out. The test is carried out according to the performance test method of ordinary air spring. The load-displacement curve and dynamic stiffness-loading frequency curve of the normal air spring in the height valve and the external height valve are measured. According to the comparison and analysis of the test results, it can be found that the variation trend of the performance curves of the built-in air spring and the ordinary air spring of the height valve is the same, and the measured curves are more in line with the actual driving conditions. It shows that it is feasible to test the performance of the air spring in the height valve according to the performance test method of the ordinary air spring. It can be seen that the performance test method of the height valve built-in air spring is consistent with that of the ordinary air spring.
