温度与尺寸变化实验项目书

®项目编号：RGKJ项目编号：技术改进项目书项目名称：工件随温度变化实验项目负责人： 立项时间： 2015年3月10日大连瑞谷科技有限公司项目名称 工件随温度变化实验项目来源（现状、存在的主要问题）由于环境温差大，造成工件尺寸变化过大，为此我和王超用了十几天时间测量十组产品，对其不同时间段，不同环境温度，工件温度，对应工件尺寸进行了测量，并统计得出结论实验内容由3月12日开始，每天去车间两趟测量，固定3到5个打废工件作为实验工件，工件的温度测量用红外线检测仪测量，环境温度用车间固定的温度计为标准，测量工件取固定测量位置，由此得出温度工件尺寸随温度变化统计表。工件尺寸随温度变化统计表，内容见副本一（工件尺寸随温度变化统计表）为了更直观的分析测量结果，制作出折线图，内容见副本2（工件随温度变化尺寸折线图）

结论已知我公司84#黄铜其线性膨胀系数是15X10-6/°C温度影响变形量公式为AL二a*AT*LT 1（△L为变形量，a为材料线性膨胀系数，△_!为温度变化量，L为材料仕温T 1度没改变时的尺寸）由此公式我列出下表1.1（材料变化尺寸与温度差对照表）在温差变化-20°到20°的时候，其相应的线性膨胀值材料变化尺寸与温度差对照表温度差r2°3。6°7°官9。10°1000.00150.0030.00450.0060.00750.0090.01050.0120.01350.015单IYitlitl2000.0030.0060.0090.0120.0150.0180.0210.0240.0270.033000.00450.0090.01350.0180.02250.0270.03150.0360.04050.0454000.0060.0120.0180.0240.030.0360.0420.0480.0540.065000.00750.0150.02250.030.03750.0450.05250.060.06750.0756000.0090.0180.0270.0360.0450.0540.0630.0720.0810.097000.01050.0210.03150.0420.05250.0630.07350.0840.09450.1058000.0120.0240.0360.0480.060.0720.0840.0960.1080.129000.01350.0270.04050.0540.06750.0810.09450.1080.12150.13510000.0150.030.0450.060.0750.090.1050.120.1350.15材料变化尺寸与温度差对照表度差ir12°13°14°15°16°17°18°19°20°1000.01650.0180.01950.0210.02250.0240.02550.0270.02850.03单位JTLJTL2000.0330.0360.0390.0420.0450.0480.0510.0540.0570.063001.04950.0540.05850.0630.06750.0720.07650.0810.08550.094000.0660.0720.07S0.0840.090.0960.1020.10S0.1140.125000.08250.090.09750.1050.11250.120.12750.1350.14250.156000.0990.1080.1170.1260.1350.1440.1530.1620.1710.187000.11550.1260.13650.1470.15750.1680.17850.1B90.19950.21B000.1320.1440.1560.1680.180.1920.2040.2160.2280.249000.14B50.1621.17550.1890.20250・2160.22950.2430.25650.2710000.1650.180.1950.210.2250.240.2550.270.2850.3
