我所用解放牌汽车底盘,按“河北长途轿”外型改装了一台工程机械电测车(见图1)。它用于工程机械强度和性能现场试验,包括载荷谱样本函数的测定。在电测车的仪表柜上,装置了动态、静态电阻应变仪,光线示波器,磁带记录器等测量仪表。动态能同时测量30个以上的应力或其它参数,静态能同时测定40～60点的应力。如配置专用的传感器,尚可完成力、力矩、流量、位移、速度、加速度等参数的测量工作。在该电测车上还装有引线杆、移动式汽油发电机组、车用空气调节器、排风扇、遥测遥讯天线、信号分线盘,检测板和收、对、扩三
I used the liberation car chassis, according to “Hebei long-distance car” appearance modified a construction machinery electric test car (see Figure 1). It is used for on-site testing of mechanical strength and performance, including the determination of the load spectrum sample function. On the meter cabinet of the electric car, there are dynamic and static resistance strain gauges, light oscilloscopes, tape recorders and other measuring instruments. Dynamic can measure more than 30 stress or other parameters at the same time, static energy can measure 40-60 points of stress at the same time. Such as the configuration of a dedicated sensor, can still complete the force, torque, flow, displacement, speed, acceleration and other parameters of the measurement work. The electric test vehicle is also equipped with a lead rod, a mobile gasoline generator set, a vehicle air conditioner, an exhaust fan, a telemetering telemetry antenna, a signal distribution board, a detection board, and a receiver, pair, and extender.
