PURPOSE: A method for computing a friction coefficient with a contact surface of a rubber block is provided to reduce costs for calculating a frictional coefficient because a deformed shape and slipped position with a contact surface of a rubber block are measured without a device for supplementing a shearing load. CONSTITUTION: A method for computing a friction coefficient with a contact surface of a rubber block is as follows. A position X where a hexahedral rubber-block, a width direction change(u), a height direction change(w), and a width direction slip are observed is measured by using a non-contact type three-dimensional spatial coordinate measuring instrument. A height(z) of the rubber block obtained when measuring amount of width direction changes and length direction changes is measured. A constant is calculated by using the measured amount of width direction changes and length direction changes. A slip generation position with respect to a contact surface and a changed shape of the rubber block are measured by the calculated constant in a compression test so that a frictional coefficient is calculated. |
