振动成型是生产混凝土制品的主要方法。目前国内外流行的振动设备,一般多为频率3000次/分、振幅0.5毫米的电动式机械偏心振动器。这种频率与振幅对振实流动性混凝土尚能普遍适用,但是对于干硬性混凝土则不一定合适。而我国当前普遍采用干硬性混凝土,因此研究适用于干硬性混凝土的振动设备有一定现实意义。电磁振动器具有频率、振幅易于调节的优点,更适应于干硬性材料。我们结合研制、使用电磁振动器的体
Vibration molding is the main method of producing concrete products. At present, the most popular vibration equipments at home and abroad are mostly electromechanical eccentric vibrators with a frequency of 3,000 times per minute and an amplitude of 0.5 mm. This frequency and amplitude is generally applicable to viscous flow concrete but may not be suitable for dry hard concrete. In China, dry hard concrete is widely used. Therefore, it is of practical significance to study vibration equipment suitable for dry and hard concrete. The electromagnetic vibrator has the advantages of easy adjustment of frequency and amplitude and is more suitable for dry hard materials. We combine the development and use of electromagnetic vibrators
