满足Tier 4-Final排放标准的VolVo SD75B和SD115B型振动压路机配有振动轮控制系统,操作人员可根据土壤类型和工作条件的变化调整压路机的振动频率和振幅。该系统标准配置有2个振动频率,另有5个可供选定。振动轮的激振力经过优化且拥有自振特性。SD75D型振动压路机的功率为54.43 k W,振动轮宽度为1.68 m,在30.8~33.8 Hz的振动频率下激振力可达96~132k N。SD115B的功率为108.85 k W,振动轮宽度为2.13 m,在
The Volvo SD75B and SD115B Vibratory Rollers, which meet Tier 4-Final emission standards, are equipped with a Vibratory Wheel Control system that allows operators to adjust the vibration frequency and amplitude of the roller based on changes in soil type and operating conditions. The system comes standard with two vibration frequencies, and another five are available for selection. Vibratory wheel excitation force is optimized and has natural vibration characteristics. The SD75D Vibratory Roller has a power of 54.43 kW and a Vibration Wheel width of 1.68 m, with an excitation force of 96 to 132 kN at a vibration frequency of 30.8 to 33.8 Hz. The SD115B has a power of 108.85 kW and a vibration wheel width of 2.13 m
