一、前言自动协调加载设备是一种数字式多点载荷控制设备。在靜态应力分析试验中,可以对五个加载点同时进行控制,以满足试验对载荷的要求。与数字应变计配用,可构成一个靜态应力分析试验系统,以满足各种复杂结构的靜态应力分析试验。航空事业的发展,对强度试验提出了更高的要求。要求试验条件尽量与被试验物的实 I. INTRODUCTION Automatic coordination loading equipment is a kind of digital multi-point load control equipment. In the static stress analysis test, five loading points can be controlled at the same time to meet the requirements of the test on the load. For use with digital strain gages, a static stress analysis test system can be constructed to meet the static stress analysis of various complex structures. The development of aviation industry has put forward higher requirements on strength tests. Requirements of the test conditions as much as possible with the test object
