锚杆质量检测中试验速度对力学性能的影响及试验控制

摘要

通过在锚杆质量检测中实验数据及理论分析，表明金属拉伸试验速度对金属杆体力学性能影响很大。依据国家标准和负荷速率公式，推导出负荷速率公式，用以指导金属杆体质量检验试验的操作。结合不同类型试验机特点，提高金属力学性能质量检验的精确度。%Bolt through the quality inspection of experimental data and theoretical analysis, Metal tensile test showed that the speed of the metal bar physical properties of a great school. Based on national standards and load rate formula, derive load rate formulas. Guide the opera-tion of inspection and test. Combine features of different types of testing machine, improve the mechanical properties of metal precision of quality control.
