GJ944195 履带推土机紧急制动动态稳定性研究[刊,中]张云龙…//工程机械.—1994,25(3).—12～14推土机紧急制动时,由于惯性力的作用导致压力中心前移,发生“翘尾”现象。文章着重对履带推土机紧急制动工况下的动态稳定性进行探讨,分析了“翘尾”机理,制定相应的力学模型,推导出最大翘尾角及最高安全车速的计算公式,并给出稳定性判别式。通过对上海-410履带推土机实测表明,理论计算与试验结果相吻合。图2参5GJ944196 推土机总体 CAD 系统总体设计[刊,中]/宋德朝…//工程机械.—1994,25(3).—15～18讨论了微机上的推土机 CAD 系统总体设计,并就汉字菜单、图形处理、工程数据库等关键技术问题提出了解决办法。图4参2(伯文)
GJ944195 Dynamic Stability of Emergency Braking Bulldozer Bulldozer [中刊] 张云龙...//Construction Machinery.—1994,25(3).—12～14 Bulldozer Emergency braking, due to inertial force leading to pressure center forward , there is a “tilt tail” phenomenon. The article focuses on the dynamic stability of crawler bulldozers under emergency braking conditions, analyzes the mechanism of “tailing”, formulates the corresponding mechanical model, and derives the formula for calculating the maximum heave angle and the maximum safe vehicle speed, and gives stability. Discriminant. The actual measurement of the Shanghai 410 crawler dozer shows that the theoretical calculations are in good agreement with the test results. Figure 2 Reference 5 GJ944196 Bulldozer Overall CAD System Overall Design [Review, Chinese]/ Song Dechao...//Construction Machinery.—1994, 25(3).—15~18 Discusses the overall design of the bulldozer CAD system on the microcomputer, and discusses the Chinese character menu. Key technical issues such as graphic processing, engineering databases, and other solutions have been proposed. Figure 4 Reference 2 (Burwen)
