一、前言TS200型湿地履带推土机是我厂研制的大型湿地施工机械。样机(见图1)于1985年8月制成,选择了与湿地推土机作业相近的场地,按照JB1666-75《履带推土机整机性能试验方法》进行了整机性能测试。还增加了“牵引负荷工况下的接地比压”测试项目,测出了该机在不同牵引负荷下的接地比压变化情况及履带接地各点的压力分布情况,样机累计进行了2000多小时的工业性试验。 I. Introduction The TS200 wetland crawler bulldozer is a large-scale wetland construction machine developed by our factory. The prototype (see Figure 1) was made in August 1985. A site similar to the wetland bulldozer operation was selected. The performance test of the whole machine was carried out in accordance with JB1666-75 “Test Method for Performance of Crawler Dozers”. Also added the “ground pressure ratio under traction load conditions” test item, measured the ground pressure change under different traction loads, and the pressure distribution at each point of the track ground. The prototype has been accumulated for more than 2,000 hours. Industrial testing.
