A uniformity waveform for a tire (T) and a rotational phase of a load drum () are measured with a load drum () pressed against the tire (T). In a waveform of the frequency domain acquired by frequency conversion of the uniformity waveform, the amplitude and phase for a component of an integer multiple of the rotational frequency of the load drum () are found and stored as a correction parameter. A corrected tire (T) uniformity waveform is calculated by subtracting from the uniformity waveform a correction waveform calculated on the basis of the correction parameter, the correction waveform being the one in the rotational phase range of the load drum () during tire measurement.

Method of correcting uniformity waveform of tire

To effectively suppress a shift of a rotating axis of an upper chuck with respect to a rotating axis of a lower chuck due to a separating force. A tire testing device () includes: vertical frames () which are supported by a lower frame (); a beam () which bridges between the vertical frames () and is movable in the vertical direction; an upper chuck () which is attached to the center of the beam (), the center corresponding to the center of the beam in the longitudinal direction; and a lower chuck () which is attached to the lower frame. When viewed from the vertical direction, a rotating axis of an upper rotating member () is positioned at the center of a straight line formed by connecting supporting points where each of the vertical frames () support the beam ().

Tire testing device

A rotary drum used in a tire testing machine has a road surface base material made of an aluminum alloy and provided with a road surface onto which a tire is pushed. The road surface is coated with a thermally-sprayed steel film having higher hardness than the road surface base material, and polished. With such a configuration, a favorable test result can be obtained.

Disclosed is a tire tester () provided with: a device frame (); a slide base () provided on the device frame () so as to be able to move up and down; a large spindle () that is attached to the slide base () and can rotatably support a large-diameter tire (T); and a small spindle () that is attached to the slide base () and can rotatably support a small-diameter tire (T) that is smaller than the large-diameter tire (T). The disclosed tire tester () can push one of the tires (Tor T) against a simulated road surface (), by means of the up/down movement of the slide base (), and perform a tire test.

Tire tester

At least one of ground contact pressure, shear stress and amount of skidding is measured at a measurement point on a tread surface of a tire. A sensor is arranged on a road surface and the measurement point is made to contact the sensor while the tire rotates. An initial position of the tire is set, where the measurement point is at a previously-set reference position and the tire is at a running start position on the road surface. The tire is made to run from the initial position to obtain a rotation angle difference &#x3b8; between a tire rotation angle until the rotation axis of the tire passes over the arrangement position of the sensor and a tire rotation angle until the measurement point contacts the road surface. The tire is set at the initial position and rotated by &#x3b8; without changing the running start position of the tire.

Method and apparatus for measuring tire performance

A mixing valve assemblyis communicated with a dedicated tankD, storing therein a compatibilizer D, via an inlet valveand is also communicated with dedicated tanksA-C via three injection valves, the tanks storing therein auxiliaries A-C respectively. A chemical formulation is prepared by selectively injecting any one(s) of four chemical agents into the mixing valve assemblyby way of on-off control of the inlet valveand the injection valves and blending together the injected chemical agents. Then, the chemical formulation is pumped into SCF by a high-pressure pumpsuch that the SCF and the chemical formulation are mixed together to form a process fluid. Thus, the number of components of a high-pressure portion can be reduced to achieve a cost reduction of an apparatus. Furthermore, a pipe line for pumping the chemical agents is simplified.

High-pressure processing apparatus and high-pressure processing method

After subjected to a developing process, a rinsing process and a replacing process in this order in a developing unitA,B, a substrate W wet with an anti-drying solution is wet-transported to a supercritical drying unitby a primary transport robot. The supercritical drying unitperforms a high-pressure drying process (supercritical drying process) in a dedicated manner. Accordingly, by virtue of the presence of the anti-drying solution, the substrate W is effectively prevented from becoming air-dry during the transportation of the substrate W.

In a center mechanism of a tire press, which the tire size is changed, the lower limit position of an upper clamp ring is changed to a shaping height corresponding to the size of the exchanged tire only by changing a setting of a controller. Consequently, the work related to the tire size change is facilitated. A bladder is inflated and tightly comes into contact with the inner face of a green tire while lowering the upper periphery of the bladder to the shaping height corresponding to the tire size. The center mechanism includes: an upper clamp mechanism such as an upper clamp ring, that holds the upper periphery of the bladder; a first cylinder for vertically moving the upper clamp mechanism by the reciprocating movement of a piston; a linear sensor for sensing the travel amount of the piston of the first cylinder; and a controller for setting the shaping height as the lower limit position of the upper clamp mechanism and for controlling the reciprocating movement of the piston on the basis of the travel amount.
