Each complete forward and backward movement constitutes one flexing cycle. This cyclical motion causes the cable to alternately bend around the pulleys and straighten as the carriage traverses its full range of motion. The bending action subjects different sections of the cable to varying mechanical stresses: the outer radius of each bend experiences tensile elongation while the inner radius undergoes compression, precisely mimicking the stress patterns that occur during real-world drum reeling operations.<\/p>\n            <p class=\"bilingual\">\u5728\u6d4b\u8bd5\u6267\u884c\u671f\u95f4\uff0c\u7535\u52a8\u6258\u67b6\u4ee5\u5927\u7ea60.33\u7c73\/\u79d2\u7684\u6307\u5b9a\u901f\u5ea6\u6cbf\u5176\u4e00\u7c73\u884c\u7a0b\u8def\u5f84\u8fde\u7eed\u6765\u56de\u79fb\u52a8\u3002\u6bcf\u6b21\u5b8c\u6574\u7684\u524d\u540e\u79fb\u52a8\u6784\u6210\u4e00\u4e2a\u6320\u66f2\u5468\u671f\u3002\u8fd9\u79cd\u5faa\u73af\u8fd0\u52a8\u5bfc\u81f4\u7535\u7f06\u5728\u6258\u67b6\u7a7f\u8fc7\u5176\u5168\u90e8\u8fd0\u52a8\u8303\u56f4\u65f6\u4ea4\u66ff\u56f4\u7ed5\u6ed1\u8f6e\u5f2f\u66f2\u548c\u62c9\u76f4\u3002\u5f2f\u66f2\u52a8\u4f5c\u4f7f\u7535\u7f06\u7684\u4e0d\u540c\u90e8\u5206\u627f\u53d7\u4e0d\u540c\u7684\u673a\u68b0\u5e94\u529b\uff1a\u6bcf\u4e2a\u5f2f\u66f2\u7684\u5916\u534a\u5f84\u7ecf\u5386\u62c9\u4f38\u4f38\u957f\uff0c\u800c\u5185\u534a\u5f84\u7ecf\u5386\u538b\u7f29\uff0c\u7cbe\u786e\u6a21\u62df\u5728\u771f\u5b9e\u4e16\u754c\u5377\u7b52\u6536\u5377\u64cd\u4f5c\u671f\u95f4\u53d1\u751f\u7684\u5e94\u529b\u6a21\u5f0f\u3002<\/p>\n\n            <h3>Electrical Continuity Monitoring | \u7535\u6c14\u8fde\u7eed\u6027\u76d1\u63a7<\/h3>\n            <p>Throughout the entire 30,000-cycle test duration, the cable operates under its rated electrical load.

The applied weights create consistent tension throughout testing, whereas real-world tension may vary with cable position and equipment movement. The standardized pulley diameter establishes a minimum bend radius that may be tighter than some operational installations. These conservative test parameters ensure that cables passing the flexing test will perform reliably under a wide range of actual deployment conditions.<\/p>\n            <p class=\"bilingual\">\u53cc\u6ed1\u8f6e\u6320\u66f2\u6d4b\u8bd5\u5305\u542b\u51e0\u4e2a\u52a0\u901f\u56e0\u7d20\uff0c\u4f7f\u6d4b\u8bd5\u6bd4\u5178\u578b\u64cd\u4f5c\u6761\u4ef6\u66f4\u4e25\u683c\uff0c\u4e3a\u7535\u7f06\u6027\u80fd\u9884\u6d4b\u63d0\u4f9b\u4fdd\u5b88\u7684\u5b89\u5168\u88d5\u5ea6\u3002\u4ee5\u6052\u5b9a\u901f\u5ea6\u8fde\u7eed\u4e0d\u95f4\u65ad\u5faa\u73af\u6d88\u9664\u4e86\u8bbe\u5907\u7a7a\u95f2\u65f6\u6b63\u5e38\u64cd\u4f5c\u671f\u95f4\u53d1\u751f\u7684\u4f11\u606f\u65f6\u95f4\u3002\u65bd\u52a0\u7684\u91cd\u91cf\u5728\u6574\u4e2a\u6d4b\u8bd5\u671f\u95f4\u4ea7\u751f\u4e00\u81f4\u7684\u5f20\u529b\uff0c\u800c\u771f\u5b9e\u4e16\u754c\u7684\u5f20\u529b\u53ef\u80fd\u968f\u7535\u7f06\u4f4d\u7f6e\u548c\u8bbe\u5907\u79fb\u52a8\u800c\u53d8\u5316\u3002\u6807\u51c6\u5316\u7684\u6ed1\u8f6e\u76f4\u5f84\u5efa\u7acb\u4e86\u6700\u5c0f\u5f2f\u66f2\u534a\u5f84\uff0c\u53ef\u80fd\u6bd4\u67d0\u4e9b\u64cd\u4f5c\u5b89\u88c5\u66f4\u7d27\u3002\u8fd9\u4e9b\u4fdd\u5b88\u7684\u6d4b\u8bd5\u53c2\u6570\u786e\u4fdd\u901a\u8fc7\u6320\u66f2\u6d4b\u8bd5\u7684\u7535\u7f06\u5728\u5e7f\u6cdb\u7684\u5b9e\u9645\u90e8\u7f72\u6761\u4ef6\u4e0b\u53ef\u9760\u5730\u6267\u884c\u3002<\/p>\n\n            <h3>Failure Mode Identification | \u5931\u6548\u6a21\u5f0f\u8bc6\u522b<\/h3>\n            <p>The continuous electrical monitoring during flexing tests provides valuable diagnostic information about how and why cables fail under repeated mechanical stress.

The three-pulley test typically operates at a slower speed of 0.1 m\/s and may use different weight loading configurations. While both test methods subject cables to repetitive flexing stress, the two-pulley test more accurately simulates the bending patterns experienced by cables in typical drum reeling applications. The choice between two-pulley and three-pulley testing depends on the specific application requirements and the cable construction being evaluated.<\/p>\n            <p class=\"bilingual\">\u4e00\u4e9b\u6d4b\u8bd5\u534f\u8bae\u91c7\u7528\u4e09\u6ed1\u8f6e\u914d\u7f6e\u800c\u4e0d\u662f\u53cc\u6ed1\u8f6e\u7cfb\u7edf\u3002\u4e09\u6ed1\u8f6e\u6d4b\u8bd5\u901a\u5e38\u4ee50.1\u7c73\/\u79d2\u7684\u8f83\u6162\u901f\u5ea6\u8fd0\u884c\uff0c\u5e76\u53ef\u80fd\u4f7f\u7528\u4e0d\u540c\u7684\u91cd\u91cf\u8d1f\u8f7d\u914d\u7f6e\u3002\u867d\u7136\u4e24\u79cd\u6d4b\u8bd5\u65b9\u6cd5\u90fd\u4f7f\u7535\u7f06\u627f\u53d7\u91cd\u590d\u7684\u6320\u66f2\u5e94\u529b\uff0c\u4f46\u53cc\u6ed1\u8f6e\u6d4b\u8bd5\u66f4\u51c6\u786e\u5730\u6a21\u62df\u4e86\u5178\u578b\u5377\u7b52\u6536\u5377\u5e94\u7528\u4e2d\u7535\u7f06\u7ecf\u5386\u7684\u5f2f\u66f2\u6a21\u5f0f\u3002\u53cc\u6ed1\u8f6e\u548c\u4e09\u6ed1\u8f6e\u6d4b\u8bd5\u4e4b\u95f4\u7684\u9009\u62e9\u53d6\u51b3\u4e8e\u5177\u4f53\u7684\u5e94\u7528\u8981\u6c42\u548c\u6b63\u5728\u8bc4\u4f30\u7684\u7535\u7f06\u7ed3\u6784\u3002<\/p>\n\n            <h3>Torsional Twist Testing | \u626d\u8f6c\u626d\u66f2\u6d4b\u8bd5<\/h3>\n            <p>Torsional twist testing evaluates cable performance under rotational stress rather than pure bending stress. This test subjects cables to repeated 360-degree or even 540-degree twisting motions in both clockwise and counterclockwise directions while monitoring electrical continuity. Torsional testing is particularly relevant for cables used in robotic applications or rotating equipment where twisting forces dominate. However, for reeling cable applications where the primary stress mechanism is bending rather than twisting, the two-pulley flexing test provides more relevant performance data.<\/p>\n            <p class=\"bilingual\">\u626d\u8f6c\u626d\u66f2\u6d4b\u8bd5\u8bc4\u4f30\u7535\u7f06\u5728\u65cb\u8f6c\u5e94\u529b\u4e0b\u7684\u6027\u80fd\uff0c\u800c\u4e0d\u662f\u7eaf\u5f2f\u66f2\u5e94\u529b\u3002\u8fd9\u4e2a\u6d4b\u8bd5\u4f7f\u7535\u7f06\u5728\u987a\u65f6\u9488\u548c\u9006\u65f6\u9488\u65b9\u5411\u91cd\u590d360\u5ea6\u751a\u81f3540\u5ea6\u7684\u626d\u66f2\u8fd0\u52a8\uff0c\u540c\u65f6\u76d1\u63a7\u7535\u6c14\u8fde\u7eed\u6027\u3002\u626d\u8f6c\u6d4b\u8bd5\u7279\u522b\u9002\u7528\u4e8e\u7528\u4e8e\u673a\u5668\u4eba\u5e94\u7528\u6216\u626d\u66f2\u529b\u5360\u4e3b\u5bfc\u5730\u4f4d\u7684\u65cb\u8f6c\u8bbe\u5907\u7684\u7535\u7f06\u3002\u7136\u800c\uff0c\u5bf9\u4e8e\u4e3b\u8981\u5e94\u529b\u673a\u5236\u662f\u5f2f\u66f2\u800c\u4e0d\u662f\u626d\u66f2\u7684\u5377\u7b52\u7535\u7f06\u5e94\u7528\uff0c\u53cc\u6ed1\u8f6e\u6320\u66f2\u6d4b\u8bd5\u63d0\u4f9b\u4e86\u66f4\u76f8\u5173\u7684\u6027\u80fd\u6570\u636e\u3002<\/p>\n        <\/section>\n\n        <section class=\"company-info\">\n            <h2>About Anhui Feichun Special Cable Co., Ltd. | \u5173\u4e8e\u5b89\u5fbd\u98de\u7eaf\u7279\u79cd\u7535\u7f06\u6709\u9650\u516c\u53f8<\/h2>\n            <p>Anhui Feichun Special Cable Co., Ltd.
