1.电气系统振动测试的必要性工程机械作业环境恶劣、作业工况多变,其电气系统故障比较频繁。以全液压振动压路机故障统计为例,与振动有直接联系的电气元器件故障概率在10%左右。所以在进行工程机械电气系统设计和电气配件选型时,必须通过振动可靠性试验来优化
1. Necessity of Vibration Test of Electrical System Due to the harsh operating environment of construction machinery and the changing working conditions, the electrical system malfunctions are frequent. For example, the failure probability of the whole hydraulic vibratory roller is about 10%, and the probability of failure of the electrical components directly related to the vibration is about 10%. So in the construction machinery electrical system design and electrical parts selection, must be through the vibration reliability test to optimize
