2、一部分内容进行翻译的。 ) Design of a Hydraulic Bending Machine Abstract:To keep pace with customer demands while phasing out old and unserviceable test equipment, the staff of the Engineer- ing Mechanics Laboratory (EML) at the USDA Forest Service, Forest Products Laboratory, designed and assembled a hydraulic
3、 bending test machine. The EML built this machine to test dimension lumber, nominal 2 in. thick and up to 12 in. deep, at spans up to 20 ft and loads up to 20,000 lbf. The hydraulic bending test machine was built using parts of a 100,000-lbf compression test frame. Added components included W12 by 6
4、5 steel beams; steel tube sections, L- sections, and threaded rods for beam attachment; I-beam spacer plates; wood block beam end supports; a 4-in. bore, 10-in. stroke hydraulic cylinder with 38,000 lbf capacity; steel plates for cylinder reinforcement; and two pivoting four-point load head assemblies. Eccentric loads that might occur during a test will not yield the positioning screws of the machine head or otherwise affect test results. Keywords: hydraulic bending machine, dimension lumber
