摘要： The invention relates to a method for applying extensometric sensors in railway tracks, in combination with electronic equipment and a post-processing of the signals and data obtained to measure the stresses on railway tracks and the like, as well as to measure contact forces between the wheel of the vehicle or train and the actual rail on which it is travelling. According to the method, the following is performed: capturing micro-deformations in a known point of the track; analyzing these micro-deformations; identifying the element corresponding to the micro-deformation signal peaks coinciding with the passage of the train over one of the cross members of the track; analyzing the micro-deformation signal peaks previously identified; obtaining signals by means of sensors (5) arranged in plates (6) screwed to the rail (7); and finally calibrating each detected micro-deformation peak and the relationship thereof with the magnitudes to be measured.

摘要： A load sensor-equipped operation apparatus. An operational member is movably operated. A reaction force member receives an operating force from the operational member, and a reaction force corresponding to the operation force. At least one pivotal connecting portion is interposed between the operational member and the reaction force member, pivotably connecting a pair of a first member and a second member relative to each other to transmit the operating force. A load sensor, which electrically detects the operating force, includes a shaft-like member, a main body member disposed to be relatively displaced in a direction perpendicular to an axis of the shaft-like member, a deformable member bridging the shaft-like member and the main body member, and a strain detecting element secured to the deformable member, which detects deformation of the deformable member. A transmittal link connects the first member to one of the shaft-like member and the main body.

摘要： A load and load direction detecting apparatus is so constructed that a shear force acts on a cylindrical strain body when a load W is applied from a displacing member to a case member in a direction perpendicular to an axis of the strain body. Thus, the strain body deforms readily. Consequently, detecting sensitivity of the value of load W is improved, which is calculated by a first differential amplifier (load value calculating unit) based on an output voltage output from a first bridge. A direction (θW) of the load W is calculated by a load direction calculator (load direction calculating unit) based on an output voltage output from a second bridge, and the output voltage output from the first bridge.

摘要： A new load cell design that is a combination of the column cell and proving ring designs while having the best features of both. The proving ring geometry is used to boost the transverse gage output giving tension and compression strain measurements that are more equal than in a column cell, while the gage placement is the same as a typical column cell, giving a superior temperature transient behavior. The device retains the high stiffness characteristics of column cells.

摘要： A pedalling efficiency indicator measures the forces acting on the crank arm of a pedacycle to compute pedalling efficiency as a function of these forces. Generally, pedalling efficiency is computed as the ratio of the normal component of force acting on the crank arm to the resultant load of the crank arm. The computation of pedalling efficiency may then be visually indicated so that the pedacyclist may use a pedalling technique to maximize efficiency.
