Force measuring support and sensor replacement and in-situ calibration method in service state of force measuring support
The invention discloses a force measuring support and a sensor replacement and in-situ calibration method in a service state of the force measuring support. The method comprises the following steps: S1, calibrating a new sensor; s2, the driving mechanism applies gradually-increased horizontal or lateral force to the two adjusting blocks on the support body, and the value of the applied horizontal or lateral force when the height of the support body rises or stops rising is recorded; s3, observing the distance between the two adjusting blocks and/or the data of the built-in sensor until the distance between the two adjusting blocks reaches a set value and/or the built-in sensor is in a disengaging state, and replacing the calibrated new sensor; s4, gradually reducing the horizontal or lateral force value applied to the two adjusting blocks by the driving mechanism until the driving mechanism is completely unloaded, and recording a new force value of the sensor between the two adjusting blocks at the moment; and S5, obtaining a standard counter-force of the support body based on a mechanical equilibrium relationship between the vertical or axial force and the horizontal or lateral force in the ascending and descending states, and calibrating a counter-force monitoring value of the support body.
本发明公开了一种测力支座及其服役状态下传感器更换及原位校准方法，包括以下步骤：S1：对新的传感器校准；S2：驱动机构对支座本体上的两调节块施加逐渐增大的水平或者侧向力，记录支座本体高度上升时或者暂停上升时所施加的水平或者侧向力值；S3：观察两调节块的间距和/或内置传感器的数据，直至两调节块的间距达到设定值和/或内置传感器处于脱空状态，更换校准后的新的传感器；S4：驱动机构逐步减小对两调节块施加的水平或者侧向力值，直至驱动机构完全卸载，记录此时两调节块之间新的传感器的力值；S5：基于上升和下降时两状态下的竖向或者轴向力与水平或者侧向力的力学平衡关系得到支座本体的标准反力，对支座本体的反力监测值进行校准。
