Abstract: An installation method and an apparatus of a strain gauge sensor are capable of driving an object to be measured to generate a deformation signal by a pushing/pulling force. At least two strain gauge sensors are installed on surfaces with different amounts of deformation and at an installation location of an electrical vehicle according to the installation method. The installation method includes Method 1: When a manual pushing/pulling force is applied, the installation location is deformed and the deforming action force is directly proportional to the pushing/pulling force. Method 2: When the pushing/pulling force is applied, the vehicle deforming direction at the installation location is independent to the pushing/pulling force moving direction. Method 3: The strain detecting direction of the strain gauge sensor is the same as the vehicle deforming direction at the installation location. Therefore, pulling or driving force data can be measured accurately.

Abstract: In order to make it possible to inspect a deteriorated state of a spindle incorporated in a machine tool without disassembling the machine tool, a command for speed V0 is output to the spindle and, when the rotating speed of the spindle reaches V0, power of a spindle motor is interrupted and a timer is started. The spindle continues to rotate with inertia while decelerating. Time T clocked by the timer when the spindle speed decreases to zero is read. When time T is outside a range between the upper and lower limits, the spindle is in the deteriorated state, and an alarm is output. When time T is not greater than the lower limit, the spindle and a bearing of the spindle are deteriorated and friction resistance increases. When time T is larger than the upper limit, oil holding force of grease of the bearing is deteriorated.
