    • A translocation-simulating loading apparatus for gear grinding machine with shaped grinding wheel is provided. The apparatus comprises a load-receiving test piece (25) disposed on the gear grinding machine with shaped grinding wheel and a load-exerting component for use in loading simulation. The gear grinding machine with shaped grinding wheel enables a linear movement along the X axis, a linear movement forward and backward along the Y axis, a linear movement along the Z axis, a rotary movement n around the Y axis, a rotary movement C around the Z axis, and a rotary movement A around the X axis. An angle α is formed between the axis L of a ball seat (17) of the load-exerting component and the X axis direction of a Y axis component (6); an angle formed between the normal line of a load receiving face a and the X direction of the coordinate system of the machine tool is α. A detection method for static stiffness distribution is provided. The method comprises: moving the load-exerting component to a load-exertion position to exert a load, by means of a coordinating movement in the X, Y, and Z axes; detecting the displacement by a displacement sensor, and detecting the simulated load by a force sensor (13); deriving a stiffness value at the load-exertion position under the simulated load; changing the load-exertion position; repeating the above steps, thus deriving a stiffness distribution under the simulated load. Employment of the load-exerting apparatus enables automatic translocation-simulating loading. The apparatus has a simple structure. Employment of the detection method enables the detection of static stiffness distribution. Operations of the method are simple.
