形状记忆破岩装置研究

ccording to many technical problems in the process of blasting, such as blast vibration, environmental pollution, safety and so on, research and develop a new rock breaker. The rock breaker is produced using TiNi shape memory alloy(SMA ) pipes as pressure elements, and its principle is illustrated, besides mechanics analysis has been done and indoor experiments of concrete rupture is conducted. Results show that the designed rock breaker has a strong strength, it works steady and quickly, above all it can break concrete.
